LOW VISCOUS, FLEXIBLE INJECTION RESIN FOR SEALING LEAKING JOINTS AND CRACKS
One component, closed cell, hydrophobic, water reactive, phthalate free, low viscosity polyurethane injection resin for stabilisation and water cut-off of large water leaks. In contact with water the SPETEC® SEAL F400 will expand and set as a permanent flexible water seal inside the crack or joint.
FIELD OF APPLICATION
• Shut off water leaks in concrete, brickwork and sewers where movement and settlement may occur.
• Injecting very fine joints, cracks and microcracks < 0.5 mm.
• Water cut-off of water leaks in foundations such as diaphragm walls, piling sheets and secant piles.
• Sealing water-carrying cracks and joints in tunnel segments.
• Curtain grouting behind tunnel, concrete, brickwork and sewer walls.
• Injection of water cut-off membranes and liners in tunnels.
• Injection of preventively placed injection tubes.
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.
