RIW Structureseal - bentonite sheet waterproofing

RIW Structureseal is a bentonite sheet waterproofing composite of high swelling sodium bentonite encapsulated between a non-woven and woven geotextile. It is used for basement tanking, sub-structures, boundary line construction, retaining walls and also as an under-slab ground floor DPM. A “needle-punch” process interlocks the geotextiles together
