Description
Ecmagrout PU F-200 is injected under pressure into a cracked, actively leaking structure. On contact with water it expands into a closed-cell foam, filling the crack and cutting off the flow — a leak can be stopped while it is still running.
Typical uses
- Active leaks in basements, lift pits and tunnels
- Crack injection in water-retaining structures
- Curtain grouting behind retaining walls
Expansion
Up to 20 times its liquid volume, depending on water contact and temperature.
