Thanks. I will keep an eye out for that. I was just trying to widen my driveway so my trailers would not fall off. I'd like to put the double wall plastic pipe like the other one I did. That one was dry and I used a jumping jack on it. Thanks for your advice.

Rule of thumb. If you cant walk on it you cant lay pipe on it. I would bet money that pipe will settle and the dirt will fall through the gapped pipe.
