Masonry Damp-Proofing

Solvent-free, silane/siloxane-based SILRES® BS products from WACKER are injected through boreholes straight into the masonry, where they react chemically to form a long-lasting horizontal waterproof barrier. This stops rising damp and any entrained harmful substances in their tracks, and so allows the masonry to dry out.

Masonry Injection for Horizontal Barriers

How a horizontal barrier with SILRES® BS works - the masonry above the horizontal chemical damp-proofing barrier (yellow) remains dry, even when moisture pushes up from below. In chemical damp-proofing, the active ingredient reacts with the building material’s silicate matrix to reduce the surface tension. This puts a stop to capillary water transport and the masonry dries out permanently.
