I have a under house garage heated that I want to put a sump type drain in so I can wash my car in the winter.
I need to saw the concrete floor a square about 3ft x 3ft in the center of garage floor, and a section 3 inch x 6ft on each side of the 3x3 ft center, this area is at or near the door to the rear of the garage, there's a good slope so drainage won't be a problem to the sump. The concrete is 3 1/2 inches thick.
Has any one used a concrete saw thats similiar to a chain saw, with a concrete blade in it?
Do they cut pretty fast?
Thanks
Tom
