Limestones pavers have softer colour variations than most natural stone.

They also have less veining and a chalky feel about them.

Each piece of limestone has a story behind its beautiful aged look.

And makes an excellent paver for your home, outdoor entertainment area or poolside.

In this article, we will answer a few important questions about limestone pavers to help you make the right choice.

Let’s start with…

What are Limestone Pavers Made of?

Limestone is a sedimentary stone that is primarily composed of calcite and is formed by nature.

Compared to travertine and sandstone, limestone pavers are a very popular natural stone with Australians for outdoor usage.

While travertine is a stone with much character, its holes make it look quite busy.

And though sandstone is a desirable paver, it’s very porous.

Which is not ideal for outdoor usage due to it attracting mould and discolouring over time.

So if you are searching for an exclusive and unique paver for your outdoor entertainment areas and pool surroundings.

Limestone pavers are an excellent choice.

Do Limestone Pavers Stain Easily?

We have noticed a common trend from customers when they visit our showroom:

They have mixed information about limestone pavers.

Many think limestone pavers are cheap, porous and stain very easily.

Whilst others have been told that limestone pavers are so durable that they are suitable for driveways.

So we want to make it clear once and for all:

The porosity, durability, suitability and cost of limestone pavers.

Are all dependent on the supplier and the quality of stone they stock.

For example, a fine limestone paver is not as durable as a bluestone paver or granite paver.

However, limestone pavers are much denser than your average travertine paver or sandstone paver.

On the other hand, while high-quality limestone pavers have great strength.

And are salt and slip tested to ensure they are suitable for installation around saltwater pools.

They are not ideal for installation in heavy traffic areas like driveways.

 

How Much are Limestone Pavers?

Like all natural stones, quality limestone pavers add value to your home.

So even though they are a higher investment now.

iIf you look at it from a long-term perspective, they’re worth every dollar.

Limestone pavers can vary in cost from $65 per/m2, all the way to $230 per/m2.

This variance in cost is not due to the limestone’s durability.

But rather the fossils and shells that have set in its formation.

This unique trait adds a lot of value to limestone pavers.

What Makes Some Limestone Pavers Superior to Others?

There are a few characteristics that distinguish a superior limestone paver from a less superior one.

These include:

• The stone’s density
• The colour of the stone and
• The cut of stone sold to the supplier.

In saying this, we urge you to be wary when investing in limestone pavers.

This is because some pavers on the market, even if they are 30mm thick.

Are actually quite porous and need to be dip-sealed to help make them less porous.

In such cases, you may even need to seal all 6 sides of the stone to protect it.

Also, there are some very low-quality limestone pavers on the market.

They’re so porous and soft that installing them around a pool, especially a saltwater one, is not ideal.

The stone will simply crumble over time and cost you even more time and money to fix.

This is why investing in the right quality stone for the area you intend to install it in, is very, very important.

Limestone Pavers Around the Pool?

If the particular limestone is carefully selected and adequately tested.

Limestone pavers can have up to double strength and durability compared to their sister paver, travertine.

As such, limestone pavers can be installed around the pool.

However, we will caution you to salt test your limestone pavers before actually investing or installing them as pool coping pavers.

We have seen limestone pavers installed in various locations around the pool including pool houses and pool surroundings.

They’re also perfect as walkway pavers and for patios, courtyards and basically anywhere else you can imagine.

 

What’s the Best Limestone Paver Pattern?

The French pattern is the most desired pattern for tumbled limestone pavers.

Basically a French pattern consists of four different sized pavers, that form a pattern which repeats itself.

The sizes include 600×400, 400×400, 400×200 and 200×200. Below is an example of this pattern.

In terms of design trends with limestone pool coping

Bullnose coping pieces are used in traditional homes or for curvy pools.

While square edge or drop edge limestone coping is used for modern contemporary homes.

See image below:

 

Do Limestone Pavers Get Hot?

Compared to granite and bluestone, limestone pavers reflect heat.

As they are made of calcite, this element does not absorb heat.

And as such, limestone pavers are an excellent choice as a poolside paver.

This is because they do not get hot underfoot.

And in the harsh Australian climate.

Where temperatures can reach 40 degrees celsius and higher.

This is a helpful characteristic for a poolside paver.

 

Along with heat-resistance.

You also want to ensure that the limestone you purchase for your poolside, is slip-resistant.

Ideally, you want to invest in a poolside paver that has a slip rating of P4 or higher.

To make sure, always ask your supplier to send you a slip rating test of the stone prior to purchase!

Do You Need to Seal Limestone Pavers?

As with all natural stone products, sealing is essential to maintain the stone’s aesthetic and longevity.

Limestone pavers are no exception to this.

Aqua Mix – Sealers Choice Gold is our recommended sealer for limestone as it keeps the stone’s natural appearance intact.

Aqua Mix® Sealer’s Choice® Gold – Rapid Cure, which contains MicroBan®, is the world leader in antimicrobial chemistry.

This sealer is able to penetrate through denser stones with smaller pores.

It also has a Low VOC (Low Volatile Organic Compound).

Which means it emits less carbon into the atmosphere.

For example, Aqua Mix only emits 46 grams of carbon per litre of sealant.

Which in the scope of things, is a very small amount of carbon pollution.

Aqua Mix Sealers and Cleaners have been used on limestone pavers globally in different environments for over 20 years.

Compared to other sealants, they are more long-wearing.

Which means you get the most bang for your buck from the product.

Conclusion

Choosing the right limestone paver will add a wealth of beauty, class, longevity and functionality to your home.

However, paving your home and surroundings is a significant investment and as such, should be one that stands the test of time.

This is why prior to investing in any natural stone pavers, it’s important to always do your research.

As we’ve mentioned earlier, the quality of a natural stone can vary between each supplier.

This is why it’s important to review the tests conducted on each stone.

And see if this information makes limestone paving an appropriate choice for your area of choice.

It’s easy to be led astray in this industry, especially when so few suppliers actually know their products.

If you’d like some guidance with your research or to chat about a specific product, you’re welcome to reach out to us.

If you want to add character and a sense of antiquity to your front or backyard, cobblestones can really help achieve this aesthetic.

Now, before we jump into how to lay cobblestones on mesh, let’s first start at the beginning.

And find out …

What are Cobblestones?

Cobblestones are based on the century old roads and walkways that are prominent in Europe.

Given their historical value, they bring a tremendous amount of character, timelessness and beauty to any space.

Cobblestones are typically made from dense stone materials such as granite, bluestone, quartzite and porphyry.

They typically have excellent grip strength.

As a result of their superb genetic makeup, they serve as a long-lasting paving solution.

With a wide selection of designs and materials, cobblestones can easily be used to create stunning outdoor spaces.

What Patterns do Cobblestones Come in?

Cobblestones are available in a wide range of styles.

These include the Chicago Pattern, Herringbone Pattern, Brick Pattern and Straight Pattern.

They are also available as loose individual pieces which gives you the chance to create your own unique design.

Below are some examples of how you can arrange cobblestones to turn your outdoor space into a stunning feature for your home.

How to Lay Cobblestones on Mesh?

Generally speaking, all cobblestones that are on mesh backing of 20-30mm thickness, are to be laid on a cement base.

Depending on where and why you are installing the cobblestones, installation methods may vary.

As such, we strongly recommend consulting your professional contractor to confirm the exact thickness required for the concrete slab.

For example, when laying cobblestones for driveways, it is recommended to install them on a reinforced concrete slab that is 120 mm thick.

Cobblestones can vary by 3 – 4 mm in size and/or thickness.

All meshed back cobblestones must have a tolerable thickness and size variation of +/- 2mm.

Cobblestone pavers with a split finish have more flexibility in size and thickness because of the split factor.

It is important to consider these size tolerances during the installation process.

Sometimes the tradesman will need to manually adjust some individual cobblestones in order to maintain the correct heights.

During installation, it is also typical to remove the odd cobblestone that has been broken during transportation.

If you want to create that traditional look with your cobblestones, you must use the appropriate installation procedure.

This includes using the proper adhesives, grout, additives, sealers and pre-sealers.

Installing cobblestones the right way will give your paving that “bulletproof” feel.

In this regard, meshed back cobblestones are easier and quicker to install.

However you must use the appropriate adhesives (glue) and grout.

Otherwise your cobblestones will fall apart and that will be costly and time consuming to fix.

When you get cobblestones with a mesh backing, they are held together on the mesh with an Epoxy Glue.

The mesh backing is made of plastic.

It has holes throughout it so that when you apply the glue to the paving.

This helps it adhere to the back of the cobble stone as well.

Together, the plastic mesh and epoxy glue cover about 50% of the cobblestone’s back.

This leaves another 50% of the space free for the paving glue to stick to the cobblestone.

To avoid the stone from de-bonding over time, it’s very important to use the right adhesive. H

ere we recommend a strong bonding and fibre reinforced ‘Non-Slump Adhesive.’

If you want your cobblestones to stand the test of time and stay glued to the cement.

Using only a stronger bonding glue is simply not enough for mesh backed cobblestones.

Let’s say that your car is parked in the driveway and you turn the steering wheel while it’s stationary.

The rubber tyres will grip onto the cobble.

And just as you are rotating the wheel, the tyres will physically rotate the stone.

If you repeat this overtime, it will cause your cobblestones to debond.

In order to avoid de-bonding and increase the strength of adhesion.

We suggest you apply a thicker amount of glue in comparison to installing other ordinary stone pavers.

Use a notch trowel that’s 15mm in width and apply it all over the concrete slab prior to installing the meshed cobblestones.

When you place the cobblestones on top of the glue, keep 10mm space free for the grout.

This means that you will have 5mm of glue under the cobblestones.

And 10mm of glue around the edges of the cobblestones.

This will ensure that all 5 sides of the cobble are somehow glued and joined to another material.

The above method of adhesion is recommended for heavy-traffic areas.

These include driveways that are exposed to more weight and vibrations.

If, on the other hand, you are installing cobblestones for an entertainment area that will only be exposed to foot traffic.

You can get away with a more ‘light’ installation method.

Now that we’ve reviewed the correct way to adhere to meshed cobblestones.

Let’s check out the best products for the installation process.

Lorax Cobblestone on mesh

If you are installing cobblestones for an entertainment area that will only be exposed to foot traffic.

You can get away with a more ‘light’ installation method.

However, if you are planning for a driveway.

You will need what we like to call ‘heavy-duty’ installation products.

This is because this area will take a lot more weight and vibrations than an area only exposed to foot traffic.

RECOMMENDED INSTALLATION PRODUCTS

Adhesive:

Depending on the area, we recommend different adhesives.

• For installation on the footpath area, we recommend a Fibre Reinforced Non-Slump Adhesive like Ardex X18.
• For driveways, we recommend the adhesive Ardex X18 mixed with the Ardex E90 Here the mixing ratio must be: 1 x 20kg bag of Ardex X18 + 2L of E90 + 4.5L of water.

Grout

The recommended grout for cobblestones is Ardex WJ50 Sanded Grout mixed with an Ardex Grout Booster.

Ardex’ WJ50 is a water-based, synthetic polymer grout additive, designed for gaps that are bigger than 3mm.

It improves the strength of adhesion, flexibility and resistance to abrasion.

Grout Booster is added to assist with the grout’s flexibility and also helps reduce efflorescence.

The best mixing ratio is 1 x Ardex WJ50 grout to be mixed with 2L Ardex Grout Booster + 2L water.

Sealers

Pre-sealing and top-sealing your cobblestones is crucial to increasing their longevity and ensuring a cleaner installation process.

Pre-sealing cobblestones helps clean off any excess grout or ‘grout haze’.

Without using stronger acidic cleaners that can damage the stone.

You may use a pre-sealer like the Aqua Mix – Pro Block.

This is an economical, natural-look, breathable, water-based penetrating sealer.

 

It is designed to resist staining caused by water-soluble minerals.

It also helps resist efflorescence migration.

However, ProBlock is not an adhesive bond breaker.

Once you have glued, pre-sealed and grouted the cobblestones, the top sealer provides the ‘final touch’ to the overall aesthetic.

A sealer like Aqua Mix Sealers Choice Gold is a premium grade, high performance penetrating/impregnating stone, tile and grout sealer and will help protect your stone.

It has built-in Microban® – Cured Sealant and is Mould & Mildew Resistant and will last up to 15 years.

 

What is the Cost of Installation Materials for Cobblestones?

The answer to this really depends on your project and its unique specifications.

So what we will do is give a quote sample and then show the cost of materials per square meter.

Like all materials, if not maintained properly, stone pavers can age and lose their elegant aesthetic and appeal.

Foot traffic, weight stress, dirt, debris and exposure to the elements, are all factors that can contribute to this deterioration.

Like all materials, if not maintained properly, stone pavers can age and lose their elegant aesthetic and appeal.

Foot traffic, weight stress, dirt, debris and exposure to the elements, are all factors that can contribute to this deterioration.

However, regular cleaning and high-quality sealing will give your natural stone pavers the best chance at retaining their original aesthetic and longevity.

In this article, we share simple strategies and steps you can take to maintain your pavers from the challenges of everyday wear and tear to keep them looking lush and new.

1. Use the Right Cleaning and Sealing Products

You have probably found that there are numerous cleaning and sealing products available on the market. These products include stain-removal, polishing creams, pre-sealers, deep cleaners, concentrated cleaners, and many others.

However, choosing the product on price point is not the best strategy for finding the best sealer or cleaning product for your particular paver. Choosing the best product depends on the type of stone you’ll be sealing, the stone’s grouting, density, porosity and many other factors. For example, your natural stone pavers might need a heavy-duty cleaner and grout removal.

In order to achieve that quality clean you want, it’s important to find the right product for your paver. If you need some assistance or advice, we suggest contacting a professional, or calling us at 1300 560 560.

2. Avoid Harsh Cleaners

Not all cleaners are created equal. More specifically, not all cleaners are designed for natural stones. We strongly suggest against using acid-based cleaners, vinegar or other harsh soap-based products on natural stones. If you use these, they will leave dull, hazy or milky stains on the stone. The best cleaning products for natural stones are pH-neutral cleaners, that are specifically designed for natural stone pavers. Another important detail is creating the solution by mixing the product and water in the right ratio, which is dependent on the soil buildup.

3. Wipe Spills Immediately

You may have heard that prevention is far more effective than cure. In the case of natural stone pavers, in the odd occasion where prevention is not possible and spills accidentally occur, wiping them immediately can save you a lot of time and money in the long term. Acidic drinks and food items, cooking oil and demineralised water can damage the natural stone’s finish and stain the stone with etch marks. To avoid long term damage, we recommend cleaning the spill as quickly as possible. Once you’ve wiped the spill, use an appropriate cleaner or stain-removal product to reduce the risk of staining.

4. Sweep Regularly

When it comes to maintaining stone paving, as overwashing can result in soiling the grout and other parts of the stone, regular sweeping is more recommended than regular wet cleaning. Dirt, grime, and grit are the key culprits to damaging your stone pavers. Regular sweeping will remove these from the floor and thus reduce the stone’s surface wear and tear.

5. Clean the Grout

Dirt, grime, grit and dust loves gathering in small spaces. This is why it’s super important to clean the grout area (the space between your pavers). To do this most effectively, mop the floor’s surface with a non-acid based detergent cleaner.Once complete, use a soft, non-scratch brush to scrub both the pavers and the grout.

6. Seal Correctly

Sealing helps protect your natural stone pavers from staining and odours. Like painting a house, sealing your pavers not only protects the underlying material but also keeps the pavers looking beautiful. While it is common for natural stone pavers to be pre-sealed prior to installation, ongoing sealing is a recommended necessity to prolong your pavers longevity, protect them from deterioration and staining and keep them as close to new as possible.

When applying the sealant, make sure you accurately follow the sealant manufacturer’s instructions. Poor application can leave residues and stains, leading to dirt accumulation and difficulties in cleaning in the long term. Avoid unnecessary peeling and scuffing by selecting a sealant that is designed for natural stone. Remember that depending on the stone and the sealant, you may need to apply several layers for maximum effect.

General Product Instructions

To make it easier for you, we wanted to share some general product instructions for applying sealant:

1. Sweep, vacuum or dust the surface thoroughly.
2. Test the sealant on a small area prior to application.
3. Apply the sealing solution using a paint pad applicator, pump sprayer, sponge or brush and allow approx 3 minutes of penetration before wiping the area dry.
4. Leave the sealant for a minimum of 30 minutes to dry before applying the second coat.
5. Ensure that no sealer is left on the surface by wiping it completely dry using clean, dry cotton, paper or microfibre towel after each application.
6. Check that the surface is completely sealed after 2 hours by applying droplets of water onto the paver. If the water penetrates, an additional application is required. If it doesn’t, your paver is now successfully sealed!

Sealing Wet Areas

If you’re sealing a paver that is exposed to a wet area, such as the space around a pool or pond, you might need a special sealant that is specifically designed to withstand such exposure. Alternatively, ensure that your natural stone pavers have been dip sealed prior to installation.

7. Maintaining Sealed Pavements or Re-sealing

After you’ve successfully applied your sealant, check the manufacturer’s instructions and note when you’ll need to reapply it. Sealants can last for as long as 15 years, however because some areas that are prone to heavier traffic than others, the sealant may wear out faster. As such, we recommend checking once every three to five years to see if resealing is required.

To check this, simply drop some water onto the surface of the paver. If the water beads and doesn’t absorb, you can probably leave it for a while.

Routine cleaning of your paver should include regular sweeping, as mentioned before, as well as mopping or lightly scrubbing the pavers with the appropriate pH-neutral detergent.

8. Allow Drying

After applying the sealant, let the paver’s dry for a minimum of 12 hours. It’s preferable to let the sealant dry for up to 24 hours, however this would depend on each manufacturer. So remember to read their instructions first and foremost.

Thinking of installing a new patio?

Or perhaps you’re looking to lay some pavers to create the perfect garden path, pool or entertainment area?

In this article, we explore the top trends when choosing stone pavers and porcelain pavers and dive into which may be most suitable for you.

And first…

What’s the difference between stone pavers and porcelain tiles?

Before choosing between natural stone pavers and porcelain pavers for your outdoor space, it’s essential you know the difference.

1. Stone pavers are unique and individualistic because natural stone is quarried from the ground and no two pavers will ever be the same. As such, no material can rival against that luxury appeal of natural stone pavers. In saying that, they have their own downfalls, especially when it comes to maintenance.
2. Porcelain pavers look very similar to natural stone pavers, however, they are manufactured. As such, they are easier to maintain and more functional for everyday purposes. They are also on average 35% cheaper than natural stone pavers. So if you’re building on a budget and love the natural look, porcelain pavers will help you achieve this aesthetic without breaking the bank.

Now let’s have a look at…

When to use Natural Stone Pavers?

Marble pavers and limestone pavers are quite distinguished in appearance and being available in a wide assortment of colours. These natural stones are often selected for indoor and outdoor settings because of their elegance and unrefined look, so it’s easy to see why they are a popular choice in contemporary designed homes and landscapes.

If you want to create a clean, minimalist and eye-catching path or indoor environment, install either marble and limestone pavers. Representing both strength and elegance, they will add a lot of character to any modern home.

Limestone is also quite unobtrusive in appearance. As such it can give a lovely organic touch even in a large backyard. Alternatively, it can be used as a trim around wooden decks or stepping stones along a garden path.

Striking and robust, granite pavers create a clean look for modern properties. As a strong and dense stone, granite is very suitable for high traffic areas and makes it an equally attractive (and practical) choice for pathways, patios or even driveways!

Bluestone pavers are another natural stone that is robust and suitable for outdoor areas with heavy foot or tyre traffic. These versatile pavers can be laid in a variety of designs like herringbone or fan shapes. Alternatively, you can use them as stepping stones.

If you love sandstone, we can relate! As a timeless stone it oozes character and makes your garden look majestic and regal. However, since it is a softer stone, it doesn’t bode well with lots of pressure and foot traffic. As such, we suggest using sandstone in areas with light or minimal traffic or simply adding it as a defining trim along your garden.

Now that we’ve reviewed natural stones, let’s have a look at…

When to use Structural Porcelain Pavers?

All porcelain pavers have a high break-load and most are designed to reduce glare from the harsh summer sun. So, not only will they stand the test of time but they will be easy to maintain, giving you all the time in the world (ish) to enjoy your space.

Let’s review which ones to use and when and where to install them!

If you love the granite look but want to install a paver that’s easier to maintain, Porcelain Granite Pavers are your answer!

With a 1200kg break load, these pavers can be installed on pretty much anything: sand, screen, pedestals. Porcelain pavers also absorb 35% less heat than their natural stone counterparts. Given Australia’s harsh desert summers, this makes them an ideal choice for outdoor (and indoor) locations.

Similar in appearance to classic travertine pavers, ivory porcelain pavers have a lighter tone. This makes them inviting, pleasant and extremely dense. Also, the staining issues that can affect natural travertine stone are completely nonexistent with porcelain pavers because they never permanently stain. Ivory porcelain pavers are popular for entertainment around the pool and are perfect as stepping stones for  pathways.

If you want a sandstone paver that is hard wearing and suitable for pool areas, you may wish to consider sandstone look porcelain pavers. These offer an elegant, yet functional, solution to outdoor entertainment. They feel like a natural sandstone underfoot and have a similar colour tone and appearance but are much easier to maintain. This is important, especially around the pool where water and acidity from plants or spilled drinks, can damage and stain natural sandstone!

If you are looking for something more earthly in tone, we suggest tuscany porcelain pavers instead of ivory porcelain pavers. They are also ideal for high traffic areas.

Limestone porcelain pavers have a similar look and feel to limestone pavers and are predominantly neutral in colour (available in both grey and beige). Beyond the advantages that porcelain pavers have over stone, Jura is more uniform in colour, thus embodying a cleaner, more minimalistic aesthetic to any patio or entertainment area.

Robust and hard to stain, porcelain pavers are useful in large outdoor entertainment areas. Typically grey in colour with copper tones, quartz porcelain pavers are almost identical to naturally occurring split-face quartz stones. Their other advantages are that they’re slip resistant, show no fracture points, and absorb less heat than natural stone quartz.

Now that you know the difference between stone pavers and porcelain pavers, it’s time to…

Choose a tile or paver that is right for you!

Finding not only the best, but the right paving solution can be quite a cumbersome and challenging experience.
