F. Willich offers a complete off-the-shelf range of innovative injection products, proven pump technology and injection accessories adapted to the requirements for waterproofing.

These can be enormous water masses, even under high pressure, for example during the piercing of fault zones in tunnel construction, but also smaller water inflows during the construction of foundation pits due to leaks in enclosure or in the concrete slab, during pipe jacking within the start or arrival pit, during shaft sinking operations or during the repair of hydraulic structures such as locks, canals or collectors.

Sealing these water inlets is one of the challenges facing the contractor to return safely and quickly to the scheduled construction sequence. In underground but as well in all other construction activities, unintentional water inflows up to severe water ingress endangering people, structures and equipment occur again and again.
