Icopal Base 400/450 P

The declared product is used as a lower 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 lower 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 400 P is covered with sand. The product is used for secondary roofs but it is also used also for strips in the roof edges, and as an underlayer.
