Rubber waterstops provide superior performance in withstanding shear movements and to resist hydrostatic pressure.
The product will elongate four times its original size and continue to near original shape after repeated movement. Rubber waterstops have a very low compression set and perform well at low temperatures.
The Williams System features sleeve-type fittings that provide fast positive splicing and precise waterstop alignment. Fittings are manufactured from the same elastomers/polymers as the waterstop.
