Expanding waterstop for reinforced concrete construction joints.
BigStop is a specially formulated construction joint waterstop consisting of a patented blend of butyl rubber and bentonite for use within reinforced concrete structures. BigStop utilises the unique sealing properties of natural Wyoming sodium bentonite, a non-toxic, chemically inert clay, which can swell many times its dry volume when in contact with water to form an impenetrable gel.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that CETCO is consulted before specifying.
