Rebar & Post-Tension Mapping in British Columbia
Post-tension cables hold a slab in compression; severing one is dangerous and structurally serious. Rebar and post-tension mapping uses GPR to lay out the reinforcement precisely, so cores, cuts and anchors land safely between them.
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.
This is the focused concrete-scanning task of mapping a structural element's reinforcement — rebar grids, post-tension tendons and their profile — so engineers and tradespeople can place penetrations and anchors without striking them.
- GPR scan to detect reinforcement and tendons
- Map the grid spacing and cable profile
- Mark clear zones for cores, cuts and anchors
- Report cover depth where required
- Rebar grids and spacing
- Post-tension cables and drape profile
- Conduit running with the reinforcement
Penetrations and anchors in reinforced and post-tensioned concrete.
Structural trades and engineers map reinforcement before anchoring or coring so the work is safe and the structural design is respected.

Rebar & Post-Tension Mapping — FAQ
Post-tension cables are under high tension; cutting one releases that force suddenly — a serious safety hazard — and can compromise the slab's structural capacity. GPR mapping locates the cables so penetrations avoid them entirely.
