QuestionA few years ago we had a pool installed. Because the back yard flooded, we raised the concrete patio about 4-5 inches prior to the pool installation. the problem is that the pool and its patio of pavers is higher than the concrete patio on the house and slopes towards the house. When it rains, the concrete patio fills with water up to the door threshholds (about 6 inches). We complained to the builder and he removed pavers on the sides and filled the area with gravel but this does not help. We have put in gutters around the patio roof but rain still pours off the roof and floods the patio. Once the rain stops, the patio drains within 1 hour. The house is u-shaped and the pool is in the center. What do you suggest?
AnswerNot good, at all. Standing water next to a house is a big no-no. I would recommend a two-pronged approach. You've already done #1...
1.) Add rain gutters to the eves of the house, and get the rainwater away from the deck as much as possible.
Then,
2.) Add an interceptor channel drain at the base of the deck, next to the house. They are pretty unobtrusive looking, but they really work, IF you maintain them - keep dirt & leaves out, just like the rain gutters.
Three manufacturers of this particular product are: ABTdrains.com, Polylok.com, and NDSPro.com. (and, yes, there are more than three - so you may find one closer to you and save of shipping)
The not-so-easy part is making them slope away from the house foundation, and convey the water to a lower portion of your property. Pick the mid-point from either end of the house, and set that as the "shallow" end of this drain - the middle of the "U" shape. Then slope it away, in both directions...its easier to go two ways with the drainage, than one, as it gets too deep on only one end to be effective in removing the water & finding a "daylight" point for the water to get out from around the pool deck.
By the way, most municipalities (or neighbors) are not happy when you dump more water on them than was going there before, so be careful where these pipes "daylight" into a drainageway.
And, its not cheep. But a new foundation because of water settlement or having a flooded house ain't cheep, either. It is, however, possible to "do it yourelf", if you follow the manufacturer's diagrams & instructions.
Its like a big set of legos, going together...if you are comfortable digging a channel to put it in, and maybe a bit of concrete to hold it into place. I had to do this for a garage entry I built at the bottom of a long driveway.
Good luck! -Marc
