To strengthen or to reduce permeability of the voids in the ground
Technique used vary according to the objectives of the treatment and the type of ground
Good quality control during grouting is a key factor for the successful completion of the process. SPICE is installed in the grouting plant and controls all grouting operations, including the electro-hydraulic grout pumps.
In loose soils, a sleeve pipe (tube à manchette) will be used, into which the grout packer is introduced.
Grouting is usually performed in two stages: firstly, bentonite cement grout is injected to fill the larger voids. Following by the injection of a liquid or ultrafine suspension grout with higher penetrability. The principal parameter to be determined is the amount of grout required.
