KÖSTER BDM Powder combines all three essential characteristics for integral waterproofing. It crystallizes, blocks capillaries, and makes the concrete water repellent. This reduces the water absorbency of the concrete, increases its compressive strength and resistance against chemical attack. It is free of corrosive ingredients and is non-sensitive to mechanical damage to the surface.
