Slab Cutting for Plumbing Without Dust Everywhere

Our crew protects the room first and keeps dust and slurry contained:

  • Scan first

GPR scanning locates conduit and lines to reduce the risk of hitting them, though no scan finds everything.

  • Protect the room

Plastic walls, floor protection, and furniture moved or covered, with flooring removed over the cut.

  • Clean openings

Straight diamond blade saw cuts go full depth, so the slab around the opening does not crack from hammering alone.

  • Break out and haul off

Concrete breaking and removal stays inside the cut lines, and debris goes out, not through the house.

  • Dust control

Wet cutting with water fed to the blade and HEPA vacuums, with slurry cleaned up as we go and no dry sweeping.

We follow the OSHA silica rule, 29 CFR 1926.1153 and Concrete Sawing and Drilling Association practices.

Who Cuts, Who Fixes the
Pipe, and Who Patches the Floor

When a slab has to be opened for plumbing, we handle the concrete from scan to patch, your licensed plumber handles the pipes, and the inspector checks the plumbing before anything is covered.

Steps for repairing a plumbing pipe under a slab, and who handles each step: our crew, your licensed plumber, or the city or county inspector

With slab cutting for plumbing split this way, nobody waits on the wrong trade. See the City of Greenville NC Inspections page.

How We Patch the Slab After the Plumber So Tile Does Not Crack

A slab patch stays flat when the trench is backfilled in compacted layers, the vapor barrier is patched, dowels tie the new concrete to the old slab, and the pour is finished flush with the floor.

  • After inspection

Nothing is covered until the plumbing passes.

  • Compacted backfill

Soil goes back in layers, with stone or clean fill around the pipes as your plumber requires, so the patch cannot sink.

  • Vapor barrier

Patched and lapped under the old slab edges to keep ground moisture out of your flooring.

  • Dowels

Rebar pins drilled into the old slab edges so the patch cannot drop or rock.

  • Flush pour

Our trench pour back is finished smooth for tile, vinyl, or carpet, or broom finished outdoors.

  • Cure, then flooring

We reinstall your flooring after the cure time we give you for your patch.

Every concrete patch after plumbing follows these steps, so the floor acts like one piece.

Older Ranch Slabs, Cast Iron Drains, and Water in the Hole

Many 1960s and 1970s ranch homes, converted garages, and additions in Greenville NC have thin older slabs over cast iron drains, so we scan and cut carefully to keep the floor around the opening from cracking. A seasonal high water table and clay can fill a hole, so we pump it out and keep the soil stable. Outdoors, about 49 inches of rain a year means every patch must drain and match.

Cutting Driveways, Patios, and Garage Slabs for Sewer and Water Lines

We call NC 811 before digging and saw cut openings in driveways, patios, sidewalks, and garage slabs. Each driveway cutting for sewer line job gets compacted backfill, dowels into the old concrete, and a broom finish matched to the surface. Garage slab cutting gets the same patch method indoors. We confirm the rules before cutting any public sidewalk or street.
