Natural Stone Pavers: The importance of using frost resistant materials

In recent  months we are seeing a rise in the number of customers wanting to adopt a similar, if not the same, stone used internally – externally. This most likely stems from increased installations of bi-fold doors allowing outside and inside to blend seamlessly together.

Unfortunately there are many retailers unaware of the importance of frost resistance for exterior natural stone. At we always ensure our limestone and marble pavers have passed the necessary frost resistance tests. We also have an infinity range of stones which allow customers to achieve the seamless look they are after by stocking both interior tiles and also the same exterior flagstones in 30mm. We always recommend a 30mm natural stone paver unless there is a solid concrete base reinforced with aluminum meshing. In this case, 20mm may be suitable.

Over the winter period we left some stone samples outside our warehouse to highlight the importance. The material in question is a dense marble tile more than suitable for  interior, high traffic areas however it is not frost resistant. The effects of even a relatively mild winter are quite showing and a clear sign of how structures of non-frost resistant stones are susceptible to the bite of frost. You’ll see how the water has entered the stone then once frozen it expands, chipping and popping small areas of the stone away from the remainder of the tile.

We can’t stress just how important using the right product for the right application is. If you are unsure, seek expert advice from a company with deep knowledge in the sourcing and importing of natural stone products.
