• A broken water pipe had caused a large sink hole to form under a townhouse driveway.
• Our investigation found that the slab had not been damaged and we recommended the hole could be filled and the driveway slab re-supported using either Polyurethane Resin Injection, or with hyflow cementitious grout aka “Mud-Jacking”.

• This older house had serious movements of the perimeter footings and the stumps under the floor. Most of Kuraby has highly plastic clay founding soils which can cause footings to seriously lift and settle and often “rotate” (lean).
• The footings had moved so much that the timber floor had become unstable and we recommended vacating and comprehensive re-stumping & replacement of the perimeter base and footings.

• The townhouse complex is located on compressible landfill which has been slowly settling for decades. We identified recent cracks and gaps and serious variations in the floor levels which would be due to active settlements of the founding materials.
• We considered a number of methods for stabilizing the house footings and the only reliable one would be using conventional underpinning, possibly incorporating some steel screw piers where a water table is encountered.
