DE NEEF® Waterproofing Injection Solutions

Leaks stop here: Fast, proven, durable.

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. The ability to quickly and permanently stop a leak in any part of a construction is therefore invaluable for contractors and owners.

The major advantages of De Neef® products include the fact that they are easy to use, are not diluted, and can be applied quickly and reliably. The portfolio is mostly based on single-component, closed cell, hydrophobic polyurethanes, which are both durable and lasting. Therefore, leaks that are stopped once will remain stopped. For taking care of leaks that slow down the progress of a job site, endanger the future of a construction, or prevent full use of a building, De Neef® has become the world's most trusted brand.
