We are having some drainage issues in our backyard. One half is pavers and a raised bed and the other half, closer to the building, is some old cement, a patch maybe 10 feet deep by 25 feet wide. We're thinking the best course may be to take up the cement and dig a drywell. Does this seem sensible and does anyone have a recommendation for a good contractor to do the job and haul away the debris? Thanks.
I had some drainage issues at my house and had considered a dry well. For us it was not a problem of flooding during rain storms like today - that water makes it out of the driveway - the problem was a low spot at the edge of the drive that kept a couple of inches of water just inside our yard. Because of clay soil where we are, it sat for weeks. If you have a large volume of water to get rid of, I would say you would need a drywell - and perhaps a deep one to get down into the sandy soil. In my situation, I dug an 8' trench where the water stood and sloped it down a bit. At the end of the trench I made a shaft about 2' in diameter and 8' deep. I was hoping to hit sand; I did not. Not wanting to dig anymore, I placed a bed of stones in the entire thing and then put an 8" pvc pipe with holes drilled into it in the trench and down into the shaft. I covered it with cloth made for the purpose so the pipe would not fill with dirt and then back filled with stones/cloth/sand and pavers on top. The entire unit works like a dry well. Even in heavy rain lasting days, it has not failed, though I know it fills; the weight of the water must disperse the lowest water into the clay.
It should not be a problem to find someone to do this kind of work (we do not). Someone recommended a contractor for something similar a couple of days ago - you could try them.
Google french drains on the 'net if you wish to learn more.
I just reread your post. I am not sure I would tamper with the concrete closest to the building; if it is sloped correctly it may be keeping water away from your house. Check with a contractor.

I agree with first commentator, but it is better to check with a contractor. Be sure to explain this problem to the contractor. I know this contractor who does a great work, he did works for our house and we are pleased with their works. Their company is CTG Construction ND NUMBER IS 718-669-8305 and ask for Millad. Hope your problem get fixed.
