Freezteq is a unique & highly effective damp-proof system which offers several major advantages over other chemical techniques. The damp-proof course system is based on siliconate solutions (in the form of circular section, pre-frozen packs called "ice Sticks"), which are inserted into holes drilled into the mortar line of the wall to be treated. The slow-melting system ensures a continuous water-repellent barrier throughout the treated area because the system depends on diffusion, which research has shown to be the most effective method for fluid distribution in masonry. Accurate dosages can be readily achieved.
