Horizontal barriers with pressure injection for voidless masonry

Fast and effective: The installation of a horizontal barrier via pressurized injection. When it is possible to ensure 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. After filling, the borehole is re-drilled and the injection process can proceed.

Suitable injection liquids for this kind of application are KÖSTER Mautrol 2C and KÖSTER Mautrol Flex 2C. Two component materials have a faster setting time which causes a quicker blockage of the capillaries. The injection can be carried out with the electrical 1C injection pump KÖSTER 1C Injection Pump.

In cases where damage is caused by rising moisture, the old plaster has to be removed from the wall. After the installation of the horizontal barrier, the application of KÖSTER Restoration Plaster is required. The KÖSTER Restoration Plaster allows the masonry to dry without damage. KÖSTER Restoration plasters are open to vapor diffusion and are hydrophobic. Salts remaining in the wall are absorbed by the KÖSTER Restoration Plasters so that salt doesn’t effloresce to the surface and doesn’t cause damage to the plaster or paint.

KÖSTER Restoration Plasters are available in different varieties (grey, white, fast and light). KÖSTER Restoration Plaster White is often used in older buildings without subsequent painting. KÖSTER Fine Plaster creates a smooth decorative surface and can be applied when desired to meet architectural goals. KÖSTER Restoration Plasters can only be painted over with breathable (open to vapor diffusion) paint such as KÖSTER Silicone Paint White.

Always adhere to the specifications in the respective Technical Guidelines.
