How do I cut off the top of a concrete culvert? Please read below.?

Question

We have a concrete culvert in the front yard that sticks up past the grass about 6-8 inches. I would like to cut it off flush with the lawn. Its about 6" thick. I have purchased a diamond cut concrete blade for my circular saw but I am nervous about the cut. Do I make several passes? Shallow then deeper and so on? From both sides? Then knock it off with a sledge? I'm not sure. Please help.

Answer 1

Rent a concrete saw from a tool rental place. Get the 14" one and that will give you a 7 inch cut. It will still take several passes and is best to use a diamond blade.

If you don't have a diamond blade that size, get several 4 or 5 of the masonary blades. What you don't use you can take back.

Your saw will only give you a 3" cut and if you have to cut in several places to get around and have not done this before, it could look pretty bad when done. The concrete saw will allow you to make your passes from the same place everytime thereby giving you a nice looking cut.

Take your diamond blade back and it will give you more than enough money to rent the concrete saw.

10 points please.

You're on the right track. You don't mention in your question how long this protrusion is, but you are going to have to make several cuts. I've cut quite a bit of concrete in the course of my years repairing and rebuilding just about everything you can think of and I know you can't cut 6" of it without special saws and blades. You'll most likely have to go about 1/2" at a time, chip off the top layers and then cut again, repeating the process till you get thru. You may also find you'll need a 4" hand held grinder to smooth off the surface of each side after the cutting and chipping away. Good luck, it's going to be a lot of work..

what's the culver for? does it belong to you or the city?
there is a reason its that high do yu know why?
will this become a trip hazard or do you plan to cover it with some sort of grill

if you find that it belong to you and its ok to cut it off then I would cut it in a rocking motion. move forward and backward do this as you continue around the culvert. Yes its better to make several passes. If possible, I would also make several cut up and down so when you tap it off in sections with your hammer.

be prepared for a major dust storm as you cut wear eye and breathing gear. take you time and stop often to look at your progress and clean you goggles

if you have to dig around the culvert to make room for your saw put the dirt in buckets or a wheel barrel

don't worry its no big deal just do once you decide that its ok to cut it off and there is no reason to have it stick out of the ground you will also want to cover it with some kind of grill so no one steps into it. (lawsuit city if they do)

Answer 4

If you use a diamond blade it will get hot and get a flat spot. It will throw chips and you will have to dig down to cut it to the right height.
Your better off to use a chainsaw with a carbon blade. You can rent them. Hope this helps you. Just remember to be safe

Answer 5

I WOULD NOT CUT IT UNTIL YOU FIND OUT WHY IT STICKS UP. IS IT THE TOP OF A SEPTIC HOLDING TANK???? IF SO YOU CANNOT CUT IT DOWN. ITS STICKS UP TO PREVENT WATER RUNOFF FROM GETTING IN AND HELPS PREVENT GROUND WATER CONTAMINATION IF THE SEPTIC WERE TO OVERFLOW DURING A FLOOD. CALL LOCAL OFFICALS BEFORE CUTTING.
