Emseal Submerseal® - submersible watertight expansion joints for continuous immersion in chlorinated, saline, potable or wastewater environments

A submerged expansion joint, Sika Emseal Submerseal® is a water resistant, joint-face-adhered, precompressed, primary seal for retrofit and new structural expansion joints and construction joints where continuous or intermittent immersion or contact with chlorinated water, saline water, potable water, and certain effluent concentrations is planned.

Featuring an arched silicone-bellows sealing surface and backed by an integral, pressure-resisting impregnated foam backing, Submerseal provides a lasting solution to joint sealing applications where constant exposure to water is expected.

The system is comprised of precompressed, silicone-and-impregnated-foam hybrid sealant installed into field-applied epoxy adhesive on the joint faces with the silicone bellows locked to the joint faces with a field-applied silicone sealant band and corner bead.
