Injecting cementitious material into a soil mass tends to reduce permeability, cause swelling and may increase strength. Grouting is a technique whereby a slow flowing water/sand/cement mix is injected under pressure. Grouting is a good option if the foundation of an existing building requires improvement, sine it is possible to inject the grout from the side or at an inclined angle. Projects engaged with:

The fundamental concept of soil nailing consists of reinforcing the ground by passive inclusions, closely spaced, to create in-situ a coherent gravity structure and thereby to increase the overall shear strength of the in-situ soil and restrain its displacements. In soil nailing, similarly to ground anchors, the load transfer mechanism and the ultimate pull-out resistance of the nails depends primarily upon soil type and strength characteristics, installation technique, drilling method size and shape of the drilled hole, as well as grouting method and pressure used.
