Emseal Submerseal

submerseal submerged expansion joint
Submerseal

Emseal Submerseal is a water resistant, joint-face-adhered, pre-compressed, 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.

 Features

  • 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
  • NSF/ANSI 61 compliant
  • Non-invasive anchoring
  • Joint-face adhered
  • Bellows never under tension during joint movement

Uses

  • Swimming pools
  • Fountains
  • Water parks
  • Water features
  • Water tanks
  • Cooling tower basins
  • Waste water treatment plants

Standard Sizes: In 6mm increments from 12mm to 100mm.
Movement Capability: +/-25% (Total 50%) of nominal material size.
Colour: Emseal standard colour is "white". Custom colours are possible but colour can impact hydrostatic head capability (contact Allco).

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.
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.
Applicable Standards: The silicone coating is compliant to NSF/ANSI Standard 61; NSF Standard 51; FDA Regulation CFR 177.2600; MIL-A-46146

Performance Limitations

  • Substrates must be solid, parallel, plumb and free of any contaminants.
  • Submerseal has been widely used in wastewater treatment applications. However, effluent concentration should be discussed with Allco. If Submerseal is not suitable to a particular concentration, contact Allco to discuss CHEMSEAL as a more suitable solution.
  • IMPORTANT - Cure Time After Installation: Emseal Submerseal cannot resist hydrostatic pressures or chemical concentrations stated unless a minimum of seven days is allowed for the injected silicone sealant bands and corner beads to fully cure. Cure time can vary based on environmental conditions. It is the responsibility of the installer to monitor cure.
