Sealing Systems Aqua Seal 
Aqua Seal from Sealing Systems is an extremely reactive two-component hydrophobic polyurethane water stop system that can be injected into flowing water. It is an exceptionally fast reacting (3-5 seconds), quick sealing and high-early-strength grout that is pumped under pressure. It is designed to stop high infiltration sources in precast or brick structures and can stop leaks in excess of 50 gpm. It comes packaged with 12 600 mLl dual-component urethane caulk tubes along with 12 static mixers.
