AGS uses grout injection and polyurethane resin injection technologies to stabilise soil and restrain vertical cuts during excavation. Beyond injection methods, we can also design and install a cement grout block, allowing excavation of the adjacent ground vertically down to the required level. This approach is often a practical alternative to sheet piling or connected concrete piling, which can be more expensive and slower to install. These systems are practical alternatives to sheet piling for many residential and small commercial sites in Perth, especially where access is tight or vibration needs to be avoided.
