Aquaseal is an extremely reactive two component hydrophobic polyurethane water stop system that can be injected into flowing water, reacting in 3 – 5 seconds. Infiltration is instantly stopped in its tracks, any void is rapidly filled, without any absorption of water.

Aquaseal is designed to stop high infiltration sources in concrete or brick structures, sealing leaks in excess of 200 litres/minute and cracks > 0.05mm. The cured polyurethane creates a mushroom like seal to permanently stop leaks, performs well in corrosive sewer environments and will resist wet/dry cycles.

Aquaseal comes packaged in 600ml dual component plastic cartridges. Specialist non-return static mixers and heavy duty dual component caulking gun is required (see other listings), making installation quick & easy.


  • Extremely fast reacting and rapid sealing
  • Will inject directly into flowing water and will not wash out
  • Will inject into the finest of fractures, rather than just covering them
  • High early strength
  • Re-sealable/reusable, use only what is needed
  • Non-hazardous, no VOCs, CFC’s or HFC’s

Applications For water control, Inflow & Infiltration in manholes, vaults and other concrete, brick or stone structures above or below ground
