Aqua Stop

Polymer Group’s Aqua Stop is a solvent free, 2-component, high strength polyurethane injection system. It is a rapid setting water stop and is also used for ground and strata consolidation. The system contains fire retardants and is self-extinguishing.



High water volume control.
Filling and stabilizing cavities in fractured rock, eg roadways, shafts etc.
Consolidating other substrates such as sand and gravel.
Concrete structure repair.


  • A fast reacting polymer with strength and rigidity
  • Will form a rigid foam in the presence of water
  • Without water, the polymer cures to a tough, resilient solid
  • It is a two-component system, with both components mixed in equal volume proportions (1:1 by volume) using a two-component injection pump coupled with a static in-line mixer
