Overview
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.
