Category creating, fully bonded, high-performance waterproofing solutions that provide continuous and durable protection preventing lateral water migration as well as ensuring full overlap compatibility
PREPRUFE® waterproofing membrane has a 30 year, 75 million m2 successful track record of protecting critical underground metro station boxes across the world. Preprufe® membrane bonds to structural concrete, giving lifetime protection against groundwater, gas and chemically contaminated soil. Cold-applied, dual-adhesive overlaps provide superior safe performance in all site conditions.

INTEGRITANK® is a fully reactive elastomeric, cold spray-applied waterproofing system designed to outlast the design life of the tunnel. It is quick and easy to apply even around details, corners and penetrations, and provides a tough, durable, fully bonded membrane which is resistant to backfill and hydrostatic pressure. INTEGRITANK® can be electrically tested post application and prior to backfill.

PREPRUFE® pre-applied waterproofing membranes combined with INTEGRITANK® or BITUTHENE® post-applied membranes provide a fully integrated solution to achieve completely dry underground spaces.

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.​
