Comparison Chart

BCS is a water-based, high grade surface sealer & sand binder for block paving & concrete. It provides a wear-resistant coating for concrete & brick surfaces and has been specially formulated for block paving, penetrating the surface and stabilising the jointing sand. Once dried, the sand and blocks are bonded together.

Using the latest technology it provides durable surface protection. On previously untreated surfaces it penetrates as well as giving a surface coating which will result in the paving having a changed appearance. This could manifest itself by giving a matt or satin sheen to the paving.

BCS can be used on a variety of concrete paving materials that may be used to create well-drained driveways, paths, walkways and patios.
