Emseal Submerseal: Submerged Expansion Joint

Emseal Submerseal is a submerged expansion joint, 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. Questions? Contact Us.


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.

  • Watertight, tensionless, arched silicone bellows
  • Resists hydrostatic head pressure
  • Resistant to saline water
  • Resistant to chlorinated water (up to 5 ppm)
  • Resistant to certain effluent concentrations (contact EMSEAL)
  • NSF/ANSI 61 compliant
  • Non-invasive anchoring
  • Joint-face adhered
  • Bellows never under tension during joint movement

Head of Water: For submerged applications this product has been tested in a hydrostatic-head pressure simulator to continuously resist water pressure of various levels without leaking. Reference the table and/or consult EMSEAL for application-specific conditions.

Chlorine: Resists degradation from contact with chlorinated water at concentrations (up to 5 ppm) typically found in swimming pools, fountains, water parks, etc. including normal and intermittent maintenance “shock” concentrations.

Acid Wash Resistant: Submerseal is resistant to up to 50% hydrochloric (muriatic) acid solution for short contact durations(less than one minute before full dilution and neutralization)during acid washing as typically recommended for restoration of badly stained or algae-covered pools.

NSF 61 Compliant: Compliant to NSF/ANSI Standard 61 for contact with potable drinking water and with FDA Regulation CFR 177.2600 for indirect contact with food.

Non-Invasive Anchoring: There are no hard metal-to-substrate connections with Submerseal. This includes embedded pins, anchors, screws, bolts or tracks, trays or rails. The system is locked to the joint faces by means of the 1) backpressure of the foam; 2) the epoxy adhesive, and 3) the field-injected silicone sealant band and corner bead at the joint face to foam-and-silicone bellows interface.

Wastewater: Effluent concentration should be discussed with EMSEAL.
