Polyurethanes
Polyurethane resins are used for the sealing of water transmission through structures, Leak Sealing.
Properties
- Variable grades for differing uses
- Low viscosity
- Not subject to synerisis or 'bleed off', complete chemical reaction
Uses
- Leak sealing
- Chemical consolidation, retention of soils
This family of grouts by many differing formulations is useful in a wide range of applications. The photos show crack penetration with a polyurethane grout, sealing leaks in fine cracks and the 'gluing together' of sands and gravels for retention of soils.
