Next generation, phthalate free, closed cell, 1-component, high performance, low viscosity, hydrophobic, HydroActive, rigid polyurethane injection grout for cutting off gushing water leaks with a high flow rate and/or high hydrostatic pressure.
Field of application:
- Designed for cutting off gushing water leaks with a high flow rate and/or high pressure.
- Used to block water leaks in diaphragm walls.
- Filling large voidssuch asrock fissures, crushed faults, gravel layers, joints, cracks and honeycombs in concrete structures that are not subject to settlement or movement.
- Injection of LDPE or HDPE membranes in tunnel construction.
- Pre-injections for waterproofing and consolidation in front of the TBM, with drill-and-blast and NATM under wet condition.
- In combination with cement and micro-fine cement for Combi-Grouting.
- For tie-back and screw rod anchoring in wet and dry conditions.
- For curtain injection into gravel for containing chemicals under wet or dry conditions.
- For soil stabilisation and anchoring in gravel.
- For screen injection behind porous structures when high velocity water streams are present.
Advantages:
- ADR free transport.
- Next generation resin with improved waterproofing performance.
- Improved cell structure of the cured compound resulting in better mechanical properties and durability.
- Phthalate free resins, REACH compliant.
- Improved performance at temperatures below 5°C, no crystallisation of HA Cut Cat AF.
- Fast, Extra-Fast and Super Extra-Fast catalysts available for applications where the standard catalyst reaction speed is insufficient due to low temperatures or very high water flow. (See respective Technical Data Sheet)
- HA Cut AF forms a rigid gasket with high strength in the joint or crack.
- Non-flammable, solvent free.
- User friendly: 1-component material.
- Controllable reaction times: by using catalyst curing times can be reduced.
- Cured compound is resistant to most organic solvents, mild acids, alkalis and microorganisms.(*)
- KTW Potable Water approved.
