Product Description
PENTENS PU-108 is a polyurethane-based hydrophobic foam water stop agent. It is injected into concrete structure cracks through high-pressure infusion, where it reacts with moisture or water in the air to foam and expand. It follows the cracks, expands rapidly, and once cured, the foam body achieves the water-stopping function.
Features
- Non-toxic.
- Excellent permeability.
- Can be injected in water.
- Will not cause new cracks.
- Can be applied under negative water pressure.
- Superior adhesion on wet surfaces.
- Holes and cracks can be effectively filled by the expanding foam.
- Good elasticity, resistant to displacement after curing, volume stable, and does not shrink.
Areas of application include
- Water tanks.
- Wastewater basins.
- Concrete honeycombs and cracks.
- Concrete secondary pouring joints.
- Stabilizer for soil and road foundations.
- Observation holes, manholes, working boxes, etc.
- Metro tunnels, underpasses, mines, dams, sluices, weirs, etc.
