What is a De Neef® injection Grout?
In fact, DE NEEF® single-component, closed-cell polyurethane injection grouts were the first of its kind to be introduced to the market. Single-component injections: Just one shot is needed. No double-drilling, complicated mixing or equipment cleaning saves you precious time.
Why choose De Neef® waterproofing?
The De Neef® portfolio provides waterproofing injection solutions that stop leaks under any circumstances and in any application - foundations, infrastructure and more. Nobody plans for a leak, so when one occurs it usually represents a cost overrun and a setback for a construction project.
What happens to the grout when it is injected?
Injection: During injection the grout will follow the path of least resistance. When the material has stopped penetrating it will continue to expand against the limits of the confined space and compress within itself,forming a dense, closed cell foam.
What is a pure Grout?
Flex SLV PURe grout expands on contact with water and quickly cures to a tough, flexible foam that is resistant to most organic solvents, mild acids, alkali, petroleum and micro-organisms.
Product Description
DE NEEF® Cut PURe is a hydrophobic polyurethane designed to fill large voids in rock fissures, gravel layers, joints, and cracks in concrete structures and for the cut-off of gushing water.
Limitations
Low temperatures will significantly affect viscosity. If site temperatures are extremely low, heat bands or heated water baths may be used on the pails before and during installation to maintain the product’s temperature. Avoid splashing water into open containers, as the material is water activated. Avoid exceeding 90˚F when warming.
Installation Guidelines
Warning: Cut PURe must be used with Cut Cat PURe. Consult the Technical Data Sheets and SDS before using.
Health and Safety
Always use protective clothing, gloves and goggles consistent with OSHA regulations. Avoid eye and skin contact. Do not ingest. Refer to SDS. For emergencies, call CHEMTREC 1-800-424-9300.
