How Waterproof Lab stops rising damp forever using Koster Crisin 76 Concentrate

Waterproof Lab has found world class recipe for arresting riding damp

Rising (or “wicking”) moisture is among the most frequently encountered causes of damage in masonry walls. The results are clearly identifiable through the spalling of plaster, damaged joints and bricks, and also through salt efflorescence and algae growth. Damage from rising moisture can be avoided by the installation of a horizontal barrier.

The easiest and most successful KÖSTER system to install a horizontal barrier in existing walls is the KÖSTER Suction Angle System with KÖSTER Crisin 76 Concentrate. KÖSTER Crisin 76 Concentrate is a very thin fluid resin which penetrates into the smallest capillaries in the building material, stops the capillary action permanently and also has a hydrophobizing effect.

Boreholes are drilled regularly spaced depending on the wall thickness. KÖSTER Crisin 76 Concentrate is injected without pressure into the wall via the KÖSTER Suction Angle and the KÖSTER Capillary Rod which acts as a wick. The pressureless system uses the same capillary action which is the cause for rising damp. Thereby rising moisture is stopped with the aid of its cause. The big advantage of the KÖSTER Capillary Rod is that it doesn’t waste material in cracks or voids. Only where the rod touches the wall of the borehole will the material be released.
