Why Hands-On Soil Testing Experience Matters for Your RPEQ Subsidence & Wall Crack Report
If you’ve noticed cracks in your walls, doors that suddenly stick, or floors that no longer feel level, you want answers you can trust. Choosing the right engineer makes all the difference.
What to Look for in Your Engineer
When you’re looking for a Subsidence Engineer Report or a Wall Crack Engineer Report, it pays to ask about the engineer’s background in field and laboratory soil testing.
Soil drill logs and lab results tell an important story about what’s happening beneath your home. An engineer who has spent years producing and interpreting that data brings a deeper understanding to every investigation.
Your house may be affected by:
- Low bearing capacity
- Soil shrinkage
- Poorly compacted landfill
- Black clay swell
Whatever the cause, hands-on soil experience helps connect the ground conditions to the movement and damage you’re seeing in your home.

Uncovering What Lies Beneath
Ground conditions can be complex and difficult to fully capture. Features such as landfill density and fill depth can vary across a site and aren’t always obvious, even with careful testing.
That’s where our background makes a real difference. Because we’ve drilled, sampled and tested soils ourselves, we know what to look for in borelogs and soil samples. That helps us pinpoint whether ground conditions, such as loose or settling fill beneath a slab, are contributing to the damage in your home.
Local Knowledge of Queensland Soils
Queensland ground conditions are diverse. Our engineers have extensive experience with:
- Highly plastic clay soils
- Poorly compacted landfill
- Alluvial deposits
- Compressible soils
- Organic soils
- Acid sulphate soils
- Marine clays
Experience Built From the Ground Up
The Forensic Engineers team has worked for some of SE Queensland’s leading soil testing companies, including Coffey International, East Coast Geotechnical, Soil Surveys and Soiltest Australia, as well as expert forensic firm ICPS Australia.
Our reports are backed by a genuine apprenticeship in soil testing and geotechnical engineering, plus decades of experience in:
- Soil test drilling
- Soil laboratory testing
- Soil descriptions
- Site classifications
- Footing and slab design: strip, pad and edge beam footings, plus conventional and waffle pod slabs
- Deep footings: conventional concrete piers, push piles, small-diameter driven timber piles and steel screw piles
- Foundation underpinning: conventional concrete, polyurethane resin, timber piles and steel screw piers
Proven Results You Can Rely On
Over the past 13 years, we have completed more than 6,000 cases. That work builds on decades of earlier experience in geotechnical soil testing, site classification and slab design.
When your home’s foundations are at stake, you deserve an RPEQ Structural Engineer with real soil knowledge.

Forensic Engineers - Soil Testing & Geotechnical Expertise
Real-World Soil Testing experience is essential for Structural Engineer Subsidence Investigations.
Forensic Engineers has decades of that experience including;
- soil test drilling
- soil lab testing
- soil descriptions
- site classifications
- footing and slab designs; strip, pad and edge beam footings, conventional and waffle pod slabs
- deep footing piering; conventional concrete piers, push-piles, small diameter driven timber piles and steel screw piles
- Foundation Underpinning; conventional concrete, polyurethane resin, timber piles and steel screw piers.
And our knowledge of regional ground conditions is second-to-none, including areas with highly plastic clays soils, poorly compacted land fill, alluvial deposits, compressible soils, or organic and acid-sulphate soils.
Our hands-on geotechnical experience is extensive. That’s why Forensic Engineers are the best choice for Structural Engineer Reports for subsidence and house foundation problems.
