SureCav’s moulded, 100% recycled polypropylene panel is proving popular with builders and architects across the country. The panel has spacer protrusions and sits in the cavity allowing a stone, slate, brick and flint outer skin to be built without the need of an additional block leaf.<br> <br> The company claims that the product guarantees the cavity remains completely clean and ensures no water penetration from wind driven rain. Being far lighter than concrete blocks, it is easy to transport and can also be used with timber frame buildings. <br> <br> Without the need for a backing block or wooden shuttering as a backing for the stone, SureCav also says cost savings can be made using its system.<br> <br>
