HYDRO ACTIVE CUT CFL AF

Next generation, phthalate free, closed cell, 1-component, high performance, low viscosity, hydrophobic, hydro-active, semi-rigid polyurethane injection grout for cutting off gushing water leaks with a high flow rate and/or high hydrostatic pressure in applications where both high strength and flexibility are required.

In its uncured form, HA CUT™ CFL AF is a dark brown, non-flammable liquid without phthalate plasticisers. HA Cut CFL AF is a next generation 1- component injection resin with improved waterproofing and water cutting performance. When it comes in contact with water, the grout expands and quickly (depending on temperature and the amount of catalyst HA Cut Cat AF used) cures to a tough, semi-rigid, closed-cell polyurethane foam that is generally unaffected by corrosive environments.

– 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 CFL AF forms a semi-rigid gasket with high strength and a small amount of flexibility 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 micro-organisms (*).

– Designed for cutting off gushing water leaks with a high flow rate and/or high hydrostatic pressure in moving or non-moving joints or cracks.
– Used to block leaks into diaphragm walls.
– Filling large voids such as rock fissures, crushed faults, gravel layers, joints, cracks and honeycombs in concrete structures that are subjected to small settlement or movement.
– For curtain injections behind tunnel segments.
– For screen injection behind porous structures when high velocity water streams are present.
