Cement
Cement based grouts include low mobility sanded grouts for ground improvement, neat cement slurry grouts for filling rock fissures to control water flow beneath dams, microfine cements for strengthening soils containing a high percentage of fines, and low density cellular concretes for void filling structures including mines and other applications when weight considerations are important.
Underwater
Lightweight, low permeability, cementitious grouts for marine rehabilitation applications. These specialized mixes include cement, preformed foam, anti-washout additives and sometimes sand. The lightweight characteristic of this material is advantageous in underwater applications where the additional loading to an existing structure or soils is a concern.
Hydrophobic Polyurethane
This multi-purpose injection resin is used in porous soils to control water flow and/or increase load bearing capacity. It is also used to stop water leaks in hairline cracks and to fill voids. An accelerator may be used to adjust the reaction time based on jobsite conditions.
Chemical
Chemical grouts are typically used in sandy or fine soils. The low viscosity associated with chemical grouts allows the permeation of these soils in order to produce a solid mass that will carry structural loads and/or control water flow.
