SikaSwell S-2 Waterstop 600mL Sausage

ONE-PART POLYURETHANE, EXTRUDABLE SWELLING WATERSTOP (BENTONITE-FREE). SikaSwell® S-2 is a specially formulated, high performance, swellable, one-component, polyurethane-based waterstop for use in all kinds of construction joints. Swelling rubber creates a compression seal within joint, blocking the passage of water.
