  • 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.

Subsidence, Wall Cracks, Structural Engineer Reports, Underpinning Engineers.

Our reports are 100% independent.

In many cases we find that a house had some settlements a long time ago and no underpinning is required.

In cases where underpinning is necessary, we provide an independent opinion on which method would be most effective and affordable.


RESIN INJECTION UNDERPINNING REQUIRED

Springfield Lakes House Subsiding; Resin Underpinning Required.

This house has a waffle-pod slab that has gradual subsidence at the front. And it is causing causing house cracks and gaps that are slowly getting larger and larger. The owner wants to stabilize the slab then start re-painting. And wisely, he called Forensic Engineers to conduct an investigation.

Our thorough Structural Engineer Report found that in this case, the ground conditions were Suitable for the Use of Polyurethane Structural Resin.ย  Deep & Shallow Injection would be required to densify the founding soils, and re-support the front of the house slab.

If you are considering Underpinning, but are confused by sales "hype", which method is the best and how much should it cost?ย  Contact Forensic Engineers for an independent opinion before signing any contract for Conventional Underpinning, Resin Underpinning, or Steel Screw Pier Underpinning.

We are on your side. And we are not trying to sell you anything!


SINK HOLES UNDER FOOTINGS & SLABS

These are common foundation issues we investigate every day.

If you find any of these things happening around your home, the most important thing is to get an expert structural engineer report to determine the cause and what needs to be done to ensure your home is stable.
In many cases the problem could develop into serious damage which can require expensive repairs.
In some cases the structure may not be affected at all by ground movements, and thank goodness!

A report from Forensic Engineers will provide peace-of-mind.

COOMERA WATERS STRUCTURAL ENGINEER REPORT REQUIRED

A brilliant Building & Pest Report spotted cracking in the top of this column and recommended that the buyer contact Forensic Engineers.

Our investigation found there had been some slight settlements during the build, but the column was "sound-as-a-pound".

And the column cracks could be repaired with cementitious grout.

A great result, and Peace of Mind for the buyer.

CRACKED STUMPS & CRACKED SLAB

CRACKED STUMPS & CRACKED SLAB: Call Forensic Engineers!. We investigated this house at Corinda this week and the damages look pretty scary. We found a number of causes and surprisingly, repairs are not too complicated and would be relatively affordable. The work includes; replace 6 or-so stumps, replace part of the small garage slab and replace the "modest" front veranda. Our accurate, independent Engineer Report explained these damages in simple terms, show a clear way forward and provide peace-of-mind.

INSURANCE FLOOD DAMAGE ENGINEER REPORT

FLOOD DAMAGES, Structural Engineer Report:.
1) Erosion & sink holes around & under swimming pool path,
2) Rain water tanks cracked & leaking,
3) Septic System backing up.
CAUSES.
Our investigation found 1) loose sands & overland flow had caused erosion around the pool, 2) the rain water tanks were well past their "use-by-date" were cracked & leaking, 3) the septic system trenches were being filled up with water leaking from the rain water tanks.
SOLUTIONS.
We recommended stabilizing the material under & around the paths with Polyurethane Resin injection. The rain tank could have a liner installed & the septic trenches would function adequately once the tank leakage was alleviated. We have the answers!
