HYDRO ACTIVE CUT™ AF

In its uncured form, HA Cut AF is a dark brown, non-flammable liquid without phthalate plasticizers. HA Cut 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, 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.
Non-phthalate resins, REACH compliant.
Improved performance at temperatures below 5°C, no crystallization 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, non-solvent formulation.
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 (*).
KTW Potable Water approved.

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 voids such as rock fissures, crushed faults, gravel layers, joints, cracks and honeycombs in concrete structures that are not subject to settlement or movement.
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 DE NEEF® Combi-Grouting and DE NEEF® Combi-Block techniques.
For curtain injection into gravel for containing chemicals under wet or dry conditions.
For screen injection behind porous structures when high velocity water streams are present.
