Water control and void filling injection
DE NEEF® Leaks Stop Here: Fast, Proven, Durable.
Underground construction is a deadline driven business.
Problems that upset your schedule need to be solved FAST. Short term deadlines shouldn’t equal short term thinking. Every minute construction is stopped adds to the cost. When money is measured in minutes, you want the best, most effective, lasting and FAST leak sealing technology. Our DE NEEF® injection materials are developed to bring the shortest possible injection cycles and give lasting solutions that reduces the risk of recurrence to the absolute minimum.
DE NEEF® injection materials give the best results:
- Hydrophobic formulation avoids dilution and product loss during injection.
- Balanced viscosity and reaction profiles combine to bring the fastest leak sealing
- > 90% closed cell and no leaching give a lasting stopping effect with a proven service life of up to 120 years.
