    I will be installing a new culvert pipe under a gravel driveway next week and was wondering what some of you guys typically do. Will be renting a mini ex to dig the old plastic pipe out. I will be putting down an erosion mat then the new pipe then backfilling the rest with new gravel. I have not done this on my own yet but did one a long time ago with my father when the moving truck crushed his. Give or take 6 years ago with that one. Any tips or suggestions would be much appreciated.

    We always install concrete pipe even if the plans call for cmp (corrugated metal pipe). It only takes one heavy truck to crush a cmp like a tin can. Even if you are installing it for an existing home that won't see heavy traffic like a construction entrance, you still have to worry about trucks like the moving truck you were talking about.

    The pipe will be concrete. There are heavy farm equipment that travel over this pipe. that's how the plastic one got crushed in the first place.

    Just make sure the bottom of the pipe is the right grade so it doesn't fill up with mud

    I'm going to be installing a culvert that connects 2 other ones. I'm assuming that there are couplers...is this true?

    They are inter locking. I'll have to post up some completed photos and how they lock in.

    I would appreciate that. I normally do not do this type of work but we are doing a lot of work for them and they just moved to the area and do not know many people.

    Install as designed and the pipe should not have problems holding up to traffic. This includes proper backfill and compaction. The pipe supplier should have installation guidelines for you. ADS has them online for their products. We have been using them without issue.
