wetBLOC

wetBLOC Technology

Unlike traditional waterproofing methods, wetBLOC uses the moisture already present in the masonry to actively transport its active components. Designed to combat rising damp and water penetration from the side, this technology is particularly suitable for structures with high moisture levels, where conventional systems often reach their physical limits.

Once applied, the polymer-active material spreads through the masonry's pore system via existing capillary moisture pathways, moving horizontally and vertically. This forms a continuous capillary-sealing zone which stops further water transport, while still allowing water vapour to pass through, enabling the masonry to dry naturally.

The way wetBLOC works.

wetBloc acts directly within the capillary system of masonry, which is where rising damp is physically transported. After application, the polymer components disperse throughout the moist pore and capillary network, where they undergo a controlled reaction to form an integrated, waterproof zone.

This integrated structure disrupts the transport of water and dissolved salts through capillaries without significantly hindering the diffusion of water vapour. This creates the foundation for the building fabric to dry out sustainably and be protected in the long term.
