Base 450 P Sand

The declared product Base 450 P Sand is used as a bottom layer in a two-layer waterproofing system from BMI Icopal, made for roofs with particularly high demands on the waterproofing. The system consists of an upper layer (Top) and a bottom layer (Base), both based on SBS-modified bitumen. SBS increases the elasticity of the waterproofing layer and provides increased joint strength and service life. Two separate waterproofing layers provide a good protection against leakage. The top side of Base 450 P is covered with sand. The product is used for secondary roofs.
