Slab Anomalies
Slab Anomaly Scanning
Voids, delamination and moisture pockets under a slab rarely show until the surface fails. GPR shows structure; moisture readings confirm water, so the two together tell the real story.
Symptoms we're called for
- A hollow or drummy sound under foot or tap
- Flooring lifting, cracking or warping without visible water
- Unexplained damp at the slab edge
- A slab that stays cold or discolours in patches
Property types
- Residential slabs and basements
- Parkades and commercial floors
- Warehouse and industrial slabs
Methods used
- GPR scanning to map structure and anomaly zones
- Moisture metering to confirm water where anomalies appear
- Acoustic checks where an active leak is suspected
- Grid mapping to define the extent of each anomaly
Limitations, stated plainly
- This is not a structural engineering assessment; an engineer remains the authority on repair
- Thick or heavily reinforced slabs limit radar depth
What you receive
- An anomaly map with extent and depth estimates
- Moisture readings distinguishing wet from dry anomalies
- Recommended next steps for engineer or contractor review
Next steps
- Have an engineer review flagged structural anomalies
- Repair the identified source of moisture before cosmetic work
- Re-scan after remediation to verify
