Permeation grouting involves injecting chemical or microfine cement stabilisers into the ground at low pressure in order to strengthen or stabilise existing soils. These stabilisers have an extremely small particle size, which enables them to travel between the soil’s larger particles without displacing them. The stabilisers fill pore spaces and bond with particles to form a cohesive mass that is resistant to water. Typical applications include:
- Stabilising the foundation soil of existing structures adjacent to new construction.
- Stabilising the sides of basements, swimming pools, and retaining wall excavations.
- Slope and embankment stabilisation.
- Improving the load bearing capacity of foundation soils pre-construction.
- Stabilisation of easement in-fill
- Earth dam stabilisation.
