FAST REACTING RIGID INJECTION RESIN WITH HIGH EXPANSION (HIGHFOAMER) FOR SEALING LARGE FLOW HIGH PRESSURE WATER LEAKS AND FOR FILLING GAPS AND VOIDS
One component, closed cell, hydrophobic, water reactive, phthalate free, low viscosity polyurethane injection resin for cut-off of large water leaks and void filling. In contact with water the SPETEC® STOP HF300 (Highfoamer) will react fast and expand drastically.
FIELD OF APPLICATION
• Water cut-off of large flow and high pressure water leaks.
• Sealing foundations and sludge walls, sheet piles, secant pile walls.
• Stabilisation and water cut-off of large cracks, voids and gravel layers.
• Pre and post injections in mines, tunnels, pipe jacking, drill & blast and TBM applications.
• Injections in combination with cement-based grout.
• Crack and gravel nests injections in concrete structures.
• Water cut-off of sewer water leaks and sewer stabilisation.
• Injection of man holes.
CONSUMPTION
Consumption has to be assessed on site and is influenced by the amount of water leaking, thickness of the concrete slab or wall, presence of voids in and around the concrete etc.
