Horizontal barriers with pressure injection for voidless masonry

Fast and effective: The installation of a horizontal barrier via pressurized injection. When it is certain that the wall is free of cracks or voids, the horizontal barrier can be installed with a pressurized injection system. Cracks and voids which become apparent during the drilling process can be filled with KOSTER Borehole Suspension. After filling, the borehole is re-drilled.

Suitable injection liquids for this kind of application are KOSTER Mautrol® 2C and KOSTER Mautrol® Flex 2C. Two component materials have a faster setting time which causes a quicker blockage of the capillaries.

In cases where damage is caused by rising moisture, the old plaster must be removed from the wall. After the installation of a horizontal barrier, apply KOSTER Restoration Plaster. KOSTER Restoration Plaster allows the masonry to dry without damage. KOSTER Restoration plasters are open to vapor diffusion and are hydrophobic. Salts remaining in the wall are absorbed by the KOSTER Restoration Plasters so the salt does not effloresce to the surface and cause damage to the plaster or paint.

KOSTER Restoration Plasters are available in different varieties (grey, white, fast and light). KOSTER Restoration Plaster 2 White is often used in older buildings without subsequent painting. KOSTER Restoration Plasters can only be painted over with breathable (open to vapor diffusion) paints such as KOSTER Silicone Paint White or KOSTER MF 1.

Always adhere to the specifications in the respective Technical Guidelines.
