Flat sawing and wall sawing make long, perfectly straight cuts in concrete: trenches, openings, joints, demolition boundaries.
Slab sawing — what for?
- French drain trench or sewer line replacement
- Basement plumbing (bathroom, laundry room)
- Foundation or garage floor repair
- Control joints in a new slab
Wall sawing — what for?
- Window and door openings (see this service →)
- Resizing or closing an existing opening
- Controlled cutting before partial wall demolition
Asphalt cutting
We cut asphalt too: utility trenches, driveway repairs, clean edges before repaving. A clean cut means an invisible repair afterwards.
A real job site: plumbing trench in a basement
Here's one of our jobs: cutting a basement concrete floor to run the city lines (drain, sewer, water). Clean cut, pipes installed, then closed back up properly.
Layout before cutting
Trench openedPrice depends on cut length and thickness. A typical basement trench runs $400 to $900.
Frequently asked questions
How thick can you saw?
A flat saw cuts to roughly 12 inches deep in one pass, and a wall saw goes deeper still by cutting from both sides. For standard residential slabs (4 to 6 in.), it is a single pass.
How much does a trench in a concrete floor cost?
We generally price by linear foot. The full grid for basement plumbing is here →
Will it create dust inside the house?
We wet cut with industrial vacuum extraction on interior work. Here is how we protect a lived-in home during cutting →
Do you remove the cut concrete?
Yes, if you want us to. We can leave the pieces on site if your contractor is handling them, or load and dispose of everything — that is our concrete removal service.
