You might also want to check beside the city...you know that curb actually belongs to them and they can stick you near a big fine if you do it without their ease ( or permit ).


You know, there are companies out here who specialize in cement adjectives and they have adjectives the right equipment to do the job properly. Even if you did find a cement adjectives bit the right size, you have to hold at least a worm-drive drill (cement cutters use gas-powered equipment) and enjoy a system for putting water on the bit as it cuts.

Otherwise, you'll lately generate a bunch of heat and dust, you'll burn out a standard drill motor, and a couple hours of frustration next, you'll just finale up calling the cement cutting company anyway.
Answers:    It depends on what sympathetic of pipe you are using......PVC 3 1/2"
Galvanized 3 3/4"
