e.stop b is an expanding strip waterstop designed to stop water infiltration through cast-in-place concrete construction joints. It expands upon contact with water to form a positive seal against the concrete. The key to e.stop b’s effectiveness is that it is highly expansive, which seals and fills voids in cracks and concrete.
