Leaks Stop Here

Underground construction pros trust versatile DE NEEF® solutions for every type of project

For decades, DE NEEF® solutions have led the way in stopping leaks where they start. Our injection grouts cover the full range of products for sealing leaks and controlling water and provide solutions for soil stabilisation. 

On many projects, our grouts and products are used together as a complete system. But our fast, proven and durable products are just the start. DE NEEF® complete solutions also feature local teams of well-trained installers, suppliers and field service engineers.

No matter what the leak, we've got you covered — anytime, anywhere.

DE NEEF® injection solutions get the job done fast

An active leak means costly project delays. That's why our injection products are fast-acting and easy to install. In fact, DE NEEF® single-component, closed-cell polyurethane injection grouts were the first of their kind to be introduced to the market.

Here's how our solutions save you time and money:

  • Single-component injections: Just one shot is needed. No double-drilling, complicated mixing or equipment cleaning saves you precious time. There's less costly waste, too.
  • No dilution, no loss: It's a simple equation: 100% resin + 100% injection time = 100% effective injection. Leaks are stopped fast and durably the first time.
