Anti-snaking swellable water-stops
The invention provides an aqueously-swellable water stop having an elongate body formed by shaping or extruding a composition mixture comprising water swelling fillers and/or polymers (e.g. Bentonite, super absorbent polymers, hydrophilic polymers), at least one elastomer or polymer, and preferably at least one plasticizer, the composition mixture when formed into an elongate water stop body having a Shore A hardness (durometer) of less than 35 and more preferably in the range of 5-35 (measured at 21° C.). The water stop body has at least one major face and a layer of pressure-sensitive adhesive attached to the face for bonding to a concrete substrate. The water stop of the invention does not require use of rigid metal and hard plastic inner cores as in prior water stop designs, and avoids curling and snaking that would allow concrete poured against the water stop to invade between the first substrate and the water stop body, and thereby providing full bonding between the water stop and thus protecting against leakage through concrete construction joints.
