DESCRIPTION

KÖSTER BDM Liquid is a chloride-free material for the integral waterproofing of concrete. The material combines all three important properties for integral waterproofing. It compacts and blocks capillary pores, makes the concrete hydrophobic and also crystallizes within the concrete. By combining these three modes of action, KÖSTER BDM Liquid reduces the water absorption capacity of the concrete and increases the mechanical and chemical resistance. Free from corrosive substances, insensitive to mechanical damage to the surface.

AREAS OF APPLICATION

KÖSTER BDM Liquid directly replaces its volume of mixing water during the production of concrete as a liquid additive. KÖSTER BDM Liquid is suitable for all concrete components with reduced water absorption requirements where low absorption is demanded such as pools, ponds, reservoirs, foundations, walls and floors, tunnels, precast concrete, etc.
