A core risks one spot. A saw cut risks the whole line.

A saw cut is a long, continuous line through the slab — so instead of risking one core location, you're risking everything along the entire cut path: post-tension tendons, rebar, conduit, radiant lines, and embedded services. A single tendon crossed by a saw is a 15–20 tonne energy release and a $20,000–$75,000+ repair; a cut conduit is an outage. GPR scans the full cut line first, marking what crosses it so the cut is planned around hazards or the line is shifted to safe concrete. On post-tensioned slabs, scanning before saw-cutting isn't optional — it's the only safe way to cut.

Coverage. A core clears a small circle; a saw cut must clear a continuous line, often many metres long, where any single crossing embed is a strike. We scan a corridor along the cut path (not just points), trace tendons and rebar that cross it, and map conduit and radiant lines in the cut zone. The deliverable is the cut line marked with every crossing hazard and the clear segments — so the operator knows exactly where to cut full-depth, where to lift the blade, and where the line must move.

Yes — trenching a slab-on-grade for new plumbing or services, and slab-removal/demolition scopes, are core saw-cutting applications. We clear the trench or removal footprint of post-tension, rebar, and embedded conduit and lines before the saw and breaker start, so demolition doesn't sever a live service or release a tendon mid-cut. For structural slab removal involving PT, we map every tendon so the structural engineer can plan controlled de-tensioning.

Heated slabs are a classic saw-cutting hazard — radiant tubing or electric mats run just below the surface, exactly where a shallow cut lands, and they're rarely where you'd guess. GPR maps the loops so cuts thread between them; where loops are too dense to avoid, we flag it so you reroute the cut. Cutting a radiant loop floods the cut and kills the heating zone — scanning first turns a guaranteed problem into a planned cut.

Yes — for routine saw-cutting clearance we scan, mark the cut line, and your crew cuts the same visit; there's no report-waiting delay unless a formal engineer's deliverable is required (e.g. cutting an opening in a PT structural slab). For long or multiple cut lines, a half-day or day rate clears the whole scope in one mobilisation, keeping the saw crew moving.

Yes — saw-cutting wall openings (doors, windows, MEP penetrations) and cutting elevated decks both need clearance, and GPR works on any orientation. Wall cuts in concrete or block-and-fill can cross rebar, conduit, and embedded services; elevated and podium decks are frequently post-tensioned. We scan the cut footprint on walls and decks the same way as floors, marking hazards before the saw goes in.
