Slab Thickness Measurement in British Columbia
Knowing a slab's real thickness matters for loads, cuts, overlays and renovations — and coring to find out is destructive and leaves holes to patch. Slab thickness measurement reads the thickness with GPR from the surface, non-destructively.
Leaks.ca is the educational leak detection hub and service-support division of Leak.ca, helping BC property owners understand leak risks and connect with professional detection services when needed.
Slab thickness measurement uses GPR to read the reflection from the back face of a slab and calculate its thickness, and to distinguish slab-on-grade from suspended construction — informing structural, load and renovation decisions without test holes.
- Scan the slab and read the back-wall reflection
- Calculate thickness from the signal
- Identify construction type
- Map thickness across the area
- Concrete slab thickness
- Slab-on-grade vs. suspended slab
- Reinforcement layout within the slab
- Variations in thickness across an area
Renovation, load assessment and structural review needing slab data without coring.
Engineers and renovation GCs get thickness and construction type non-destructively, avoiding test cores and the patching they require.

Slab Thickness Measurement — FAQ
Yes. GPR reads the reflection from the back of the slab and calculates thickness from the signal timing — non-destructively and across an area — so there's no need to core test holes and patch them afterward.
