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.

Barrier Installation
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.

Figure 2 shows a macroscopic image of a brick fragment treated with wetBloc after being dried under ambient conditions for four weeks. The state of the brick material drying above the waterproofing layer is visible.
Job Title
Figure 3: Epifluorescence micrograph of a brick treated with wetBloc (scale bar: 50 µm). The visible pores and capillaries form the pathways for moisture transport within the building material. Gel-like wetBloc structures are visible within the capillary network and located throughout the pore system.
