GDS are a leading provider of Grouting Solutions. Our specialist equipment and experienced technicians inject cementitious and chemical grouts to control erosion, fill voids, increase load-bearing capabilities and improve soil and strata safety.

Permeation Grouting

Permeation Grouting is used to create barriers to groundwater, underpin foundations, provide excavation support, as well as Stabilized and strengthen granular soils. The process involves permeating granular soils with flowable particulate grouts to create a cemented mass.

Microfine Grouts

Our microfine cements work quickly and effectively to stabilize any type of soil. Our certified engineers assess your site and designs to determine the strength and thickness needed.

Dam Curtains

Dam grouting is a method for installing up-gradient and down-gradient barriers in dam foundations. GDS use specialist grout to install Dam Curtains and fix seepage problems.

Backfill / Waterproofing

Our waterproofing grouts are designed with anti-washout properties for tidal zone applications and can be used for a wide range of conditions, densities and performance specifications including seawalls, dams, and piers. Our lightweight, flowable and self-compacting backfill ensures void filling and can be formulated to be permeable or impermeable.

Bentonite / Silicate

Chemical grout stabilization is an increasingly popular alternative on excavation sites. Unlike ground retention methods such as Contiguous Piling or Shore Piling, Chemical Grouts are less expensive and reduce damage to neighboring properties from vibration
