Polyurethane for Stopping Leaks in Concrete
Spetec PUR H100 is a one-component, closed-cell, hydrophobic, water-reactive, solvent, and phthalate-free, low viscosity resin. It’s widely specified by engineers to stop leaks in concrete, especially large gushing leaks. For other ways to fix water leaks, see the page on Leak Seal.
Available Sizes
Applications
- Water cut-off of large flow and high pressure water leaks.
- Water cut-off of water leaks in foundations such as diaphragm walls, piling sheets and secant piles.
- Stabilization 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 layer injections in concrete structures.
- Soil stabilization and anchors in porous geology.
- Water cut-off of sewer water leaks and sewer stabilization.
- Probe grouting for below grade pipes.
- Manhole injections.
Advantages
