How To Cut A Drain Groove In Concrete Floor: Fastest & Simplest Way To Cut A Drain Groove Into A Concrete


Fastest & Simplest Way To Cut A Drain Groove Into A Concrete Floor

A drainage groove is a depression in concrete that lets water flow into a drainage system or away from a foundation. Drainage channels are frequently created during concrete installation before the concrete cures. However, you can create drainage grooves using a walk-behind concrete saw and some mortar if you decide you need them after the concrete has dried and hardened. A concrete floor is intended to be solid, strong, and resilient. These benefits make it ideal for a garage, basement, or subfloor, but it can be difficult to make significant remodeling alterations, like adding a new bathroom over a concrete floor. A diamond-blade wet concrete/asphalt saw, which you can hire from many tool rental facilities, is the fastest and simplest way to cut a drain groove into a concrete floor to accommodate plumbing, electrical, or another function.

Things Needed

  • Tape Measure
  • Chalk Line
  • Safety Glasses
  • Hearing Protection
  • Steel-Toed Boots
  • Wet Concrete Saw
  • Garden Hose
  • Metal Pry Bar, 5-Foot Length

Step 1: Locate The Area Of The Concrete Floor To Cut The Groove

Determine where on the concrete floor you want to carve the groove. Make sure there are no plumbing or electrical lines under the chosen groove. Measure with a tape measure, mark the groove's ends with pencil, then snap chalk lines to define the area that needs to be cut.

Step 2: Don Safety Glasses, Hearing Protection And Steel-toed Boots

Put on steel-toed boots, safety glasses, and hearing protection for protection. Garden hoses should have one end connected to a hose bib and the other end to the concrete saw's input. To begin the flow of water, turn on the hose.

Step 3: Position The Saw Over The End Of The Groove

Place the saw perpendicular to the groove's length above the end of the groove. Pull the starter cord, turn on the saw's cutoff switch, and choke the engine. After the engine starts, release the choke and give it a few seconds to warm up. To gently lower the blade to the appropriate cut depth, turn the depth handle. Push the saw forward gradually until the groove's end is cut.

Step 4: Reposition The Saw At The End Of One Of The Two Chalk Lines

Reposition the saw at the end of one of the two chalk lines designating the groove edge by raising the blade. Push the saw forward carefully until the first edge of the groove is cut, then gently press the blade of the saw into the concrete. Raise the blade, reposition the saw at the groove's end, and cut the second edge similarly to the first.

Step 5: Loosen The Channel Of Cut Concrete

To remove the loose part of the cut concrete groove, slide the flat edge of a 5-foot metal pry bar under the end of the groove and pry up.

Useful Tip

Rent an electric or pneumatic saw rather than a gasoline-powered one if you need to cut anything inside because running an engine inside can make you sick from carbon monoxide.
