Soil stabilization is applied by Grondinjectie Nederland mainly for underground construction next to existing buildings. These are often buildings with a steel foundation.
Before starting to inject the substrate, an expert calculates the desired excavation depth and the forces to be absorbed. This is done by drawing up a dimension calculation. A working drawing can then be drawn up, which is leading for the placement of the injection points.
With soil injection, excavation can be carried out without further soil barrier or foundation replacement. Because the soil injection is vibration-free, there is no construction risk for the surrounding buildings. The soil injection is carried out by permeation grouting. This is the controlled addition of injection liquid with a glass hardener in the pores of the existing sand layer.
The injected liquid forms balls which, after fusing and hardening, form a solid layer in the soil, which serves to support the foundation and removes the risk of subsidence during construction. Construction work can then commence after seven days.
In underground construction, soil stabilization is an alternative to, among other things, bricklaying, a Berliner wall or a sheet pile wall.
The benefits of soil stabilization through soil injection are:
– Optimal use of existing building space;
– Installation of site materials can be done at up to 50 m from the work;
– No sheet piling or Berliner walls required
Grondinjectie Nederland offers soil stabilization for building:
– Parking garages;
– Ground barriers or quay walls;
– Sewage traces;
– Settling tanks;
– Lift shafts.
