Whether you're a homeowner tackling a DIY project or a contractor bidding on jobs, understanding common concrete cutting work is essential. From plumbing access to garage floor replacements, certain projects require cutting through concrete.
As an experienced concrete cutting contractor, we've worked on nearly every type of job out there. In this article, we'll outline some of the most frequent concrete cutting projects and tips for preparing and planning each one.
Cutting for Plumbing Access
One of the most basic yet common jobs is cutting concrete for plumbing access. This often involves cutting through slabs or foundation walls to install or repair pipes.
Proper preparation is key. Use pipe and cable locators to avoid cutting into live utilities. Mark proposed cut lines accurately to minimize waste.
For small cuts, rent a compact wet saw. Larger jobs may require jackhammers or wall saws. Cut 1-2 inches wider than pipe diameter for flexibility during installation.
Seal cuts properly afterwards to prevent water intrusion. Concrete patching materials like hydraulic cement ensure a durable, watertight seal.
Installing New Windows or Doors
Remodeling projects often involve installing larger windows or doors that require cutting the concrete foundation. Measure opening sizes carefully in advance.
Mark cut lines at least 1.5-2 inches beyond new framing to allow for flashing/sealant. Rent a walk-behind saw for straight cuts. Use chipping hammers in tight corners.
Remove all debris thoroughly before setting new frames. Apply foundation coating or flashing to protect exposed concrete edges from water damage over time.
Garage Floor Replacements
Worn, cracked garage floors are a common DIY or contractor project. Proper planning streamlines the job.
Scan for embedded rebar or obstructions with ground penetrating radar. Mark utility locations in the slab.
Rent a walk-behind saw to score perimeter and section lines. Chip out sections with a breaker hammer. Haul away debris immediately in a dumpster.
Prepare subgrade with gravel and vapor barrier. Lay and finish new concrete same-day for uniform curing.
Sidewalk, Curbs and Driveway Repairs
Cracked or settling sidewalks and driveways are safety issues that require replacement sections. Mark sections for removal with chalk line.
Use a gas-powered walk-behind saw to cut perimeter and relief cuts. Rent an excavator, backhoe or jackhammer to break and remove pieces.
Inspect base material and re-compact if needed before pouring new concrete. Apply concrete sealer to finished work for protection against de-icing salts or other chemicals.
Basement Renovations
Gut reno basements often involve removing portions of concrete walls or floors. Use ground penetrating radar to locate rebar layout beforehand.
Score cut lines first with a walk-behind saw before breaking out sections with an excavator, jackhammer or wall saw. Transport debris immediately to avoid making a mess.
Inspect existing drainage and install foundation drainage system if needed before backfilling. Apply waterproofing to exposed surfaces.
Warehouse Floor Repairs
Heavy industrial floors undergo tremendous wear over time. Deep cracks or settling slabs require section replacement.
Use ground penetrating radar to locate rebar layouts and embedded utilities beneath floors beforehand. Score perimeter cuts first with a gas-powered saw.
Rent an excavator or backhoe to efficiently break out sections. Inspect base material and re-compact if needed before pouring. Apply high-strength industrial floor coating after curing.
