The Problem With Natural Stone Paving

Like almost all materials that are used on patios & driveways. natural stone such as Indian limestone and sandstone are porous, otherwise known as permeable. This means that they will allow moisture to absorb into the surface of the stone.  

As with any exterior surface, moisture can cause issues on natural stone, potentially causing cracking and other water damage, a build up of green growth and generally can cause wear and tear to the stone that can affect the aesthetic appeal of your patio or driveway.

By using a waterproofing treatment, you can protect your natural stone surfaces, keeping them looking like new for years to come.

What Makes Our Natural Stone Sealer Superior?

As the word 'sealer' may suggest, many waterproofing products completely prevent the movement of moisture in and out of the sealant. This is the case with many traditional concrete sealers that create a film on the surface of the stone patio or driveway in order to repel moisture.

However, while preventing moisture from entering the property, by sealing natural stone, these products also prevent any moisture from escaping from inside substrate, leading to an eventual build of moisture that will cause the sealer to fail.

As ProPERLA penetrates into the surface and chemically bonds to it, it does not create this damaging film, allowing the stone to remain breathable, which means that while water cannot absorb into the natural stone due to the water repellency, it can allow water vapour to escape through the tiny pours in the stone.
