The ES Seal System is an ideal solution for joints where large movements are expected because of temperature effect, settlement or seismic activities. The construction of the polymer seal consists of layers of reinforcement combined with layers of a specific polymer compound that matches the movement characteristics of the joint. The system is designed using force-compression curves and elongation limits at various water pressure, meeting performance and safety requirements. The clamping arrangement keeps the seal in place and makes the joint watertight for the lifetime of the structure. The relaxation effect of the seal design virtually eliminates any maintenance needed to keep the system performing. Based on material testing, ES Seals have a projected service life of over 100 years in an operating environment between -23 F to 160 F (-30C to 71 C). (-30 C to 71 C) when protected from contact with hazardous or corrosive materials.
