The below mentioned injection methods range from packer injection via a Tube a Manchette (TaM) to direct packer injection into rock, doing it per stages or globally and in a descending/ascending ways.
This technique is generally used to reduce permeability and/or to strengthen and stiffen the ground. It consists on grout filling of accessible pores between the solid particles in a permeable soil
Hydro Fracture Grouting
This technique involves the deliberate fracturing of the soil or rock by grout under pressure. The resulting compaction and stiffening of the rock or soil mass can, in appropriate conditions, provide ground improvement where permeation grouting is not practicable.
It is an active technique to mitigate settlement arising from other engineering works in order to provide protection to existing structures. Compensation grouting can take the form of permeation, compaction, or hydro fracture grouting depending on the local conditions of the given project.
This technique involves the injection of stiff mortar or paste instead of grout to displace and compact the soil, thus improving its mechanical characteristics.
This technique is particularly employed for dam construction and tunnelling. It comprises grout infilling of discontinuities, fissures, fractures or joints in mass rock with the intention of reducing permeability and increasing the competence of the mass rock.
