• A broken water pipe had caused a large sink hole to form under a townhouse driveway.
• The residents we are afraid that the driveway could collapse and that other damages might appear!
• Thank goodness that our Expert Investigation found that the slab had not been damaged.
• The damage was localized.
• So 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.
• So we recommended vacating the house. And then 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.
