A concrete floor is designed to be sturdy and powerful, and take a great deal of abuse. When these advantages make it good for a garage, basement or subfloor, creating major remodeling changes, such as installing a new bathroom on a concrete floor, could be challenging. If you need to cut a shallow station into a concrete floor to accommodate plumbing, electrical or another purpose, the fastest and simplest way is having a diamond-blade moist concrete/asphalt saw, which you may rent from many tool rental centers.
Find the area of the concrete floor at which you want to lower the station. Check to be sure there are no electrical or plumbing lines running beneath the desired station. Measure with a tape measure and make pencil marks signifying each end of the station, then snap chalk lines to mark the perimeter to be cut.
Don safety glasses, hearing protection and steel-toed boots for protection. Connect one end of a garden hose into a hose bib, then connect the other end to the inlet on a concrete saw. Turn on the hose to initiate the flow of water.
Position the saw over the end of the station, perpendicular to the length of the station. Turn on the saw’s cutoff switch, choke the motor and pull on the starter cord. When the engine fires, switch the cum off and allow the motor to warm up for approximately 30 seconds.
Expand the thickness handle to lessen the blade down to the desired depth of cut. Alleviate the saw forward until the close of the station is cut.
Raise the blade and then reposition the saw at the end of one of the two chalk lines denoting the edge of the station. Alleviate the saw’s blade into the concrete and gradually push the saw forward until the first edge of the station is cut. Raise the blade, pull the back to the end of the station, and cut on the second edge as you did the first.
Slide the horizontal edge of a 5-foot metal pry bar under the end of the station and sloping up to loosen the station of cut concrete, then pull out the loosened segment.
