Concrete scanning and slab cutting for plumbing in Bradford.

Before a drain goes under a commercial floor, the slab is scanned for rebar, conduit and cables, then cut and chipped cleanly along the planned route. One crew, one quote, from scan to backfill.

Why scan the concrete before cutting a slab for plumbing?

Scanning shows what is inside the slab before the saw touches it: rebar, electrical conduit, post-tension cables and existing pipes. Cutting blind risks a severed service, a structural repair or an injury. Seal Plumbing scans first, marks the route, then cuts and chips only what the new drain needs.

Adding washrooms, a commercial kitchen or floor drains to an existing Bradford unit usually means opening the slab. Older buildings on Holland Street and newer tilt-up units along the Highway 400 corridor hide different things in the concrete, so we scan every cut line before the saw starts and mark conduit, rebar and existing drains on the floor.

The cut follows the drain route from the mechanical drawings, with the trench sized for the pipe, the bedding and the slope. We chip out the concrete, excavate to the invert elevation, set the drains and have the underground inspection passed before backfill and the slab patch. See commercial drain, vent and water line installation for what goes into the trench.

Because the same crew scans, cuts and installs, there is no hand-off between a cutting contractor and the plumber, and the quote covers the whole sequence. Dust control and site protection are part of the job on occupied buildings.

How does concrete scanning & slab cutting work in Bradford?

Scan, mark, cut, install, inspect, patch. Each step is done before the next so nothing is cut twice.

1

Scan and mark

The slab is scanned along the planned route and any rebar, conduit, cables or existing pipes are marked on the floor.

2

Cut and chip

The slab is cut to the trench width with dust control, chipped out and excavated to the drain depth.

3

Install and inspect

Drains are set to slope on proper bedding and the underground inspection is passed before anything is covered.

4

Backfill and patch

The trench is backfilled and compacted and the slab is patched flush, ready for flooring.

What does concrete scanning & slab cutting cost in Bradford?

Concrete scanning and slab cutting in Bradford is quoted in writing with the underground plumbing it serves, within 24 to 48 hours of receiving the drawings. The price depends on the length of trench, the slab thickness, what the scan finds in the way and the condition of the subgrade.

Trench length and depthLonger runs and deeper inverts mean more cutting, chipping and excavation.
Slab thicknessThicker or reinforced slabs take longer to cut and chip.
ObstructionsConduit, cables or existing drains in the route change the plan and the price.

Commercial quotes are itemized by phase and submitted in writing within 24 to 48 hours of receiving the drawings. The written quote is the number that counts; changes to the drawings or scope are priced as change orders, also in writing.

Yes. The trench is backfilled, compacted and patched flush so flooring can go down over it.
Yes. The underground plumbing inspection is booked and passed before the trench is backfilled.
Both. The same crew scans, cuts, installs the drains and patches, under one quote.
