damp proofing

Rising damp is among the most frequently encountered causes of damage to masonry walls. The results are usually clearly identifiable through spalling of plaster, damaged joints and bricks, but also through salt efflorescence and algae growth.

Over time rising damp in combination with salt contamination and/or frost can destroy masonry structurally. Considering the decrease in the remaining lifespans of such buildings, rising damp causes significant financial damage every year.

KÖSTER™ Crisin 76 stops rising damp with the following effects: It first lines the capillaries with a water repellent film. In the next step it narrows the pore diameter to the extent that the capillary action cannot take place anymore.

The combination of these effects together ensure that KÖSTER™ Crisin 76 works every time, regardless of the pore structure, salt or moisture content. It penetrates deeply into the smallest capillaries in building materials and permanently stops capillary action.

Due to the hydrophobic effect of KÖSTER™ Crisin 76, the drying process in the wall begins immediately, creating an active horizontal barrier as soon as the system has been installed.

The patented KÖSTER™ Suction Angle System is the result of decades of experience and development work by the KÖSTER™ BAUCHEMIE AG. The horizontal damp proofing barrier is distributed through the capillary transport itself, stopping the rising damp with its own physical cause.
