​​​​​​​​​​Geogrouting / Soil Injections

​​​The best preparation and engineering studies do not always foresee the threat or magnitude of loose soil, fractured rock, collapse or large water inflows encountered in tunnelling, excavation and other underground construction operations. Unexpected problems often stop or delay construction and cause costly logistical challenges. With more than 35 years of experience and applied knowledge, De Neef® rapidly identifies and solves problems to put operations back in business.

Innovative chemical grouts and injection technologies stop fast moving water and strengthen heterogeneous soils.  De Neef® products and solutions provide fast strength development and can be applied to all soil types. The lowest soil permeability that can be injected with De Neef® products is 10-6 m/s, which is just above clay.​
