My neighbor's lot is higher than ours. We are working together to resolve the problem which, when it rains heavily, his backyard floods and the water goes into my house along the wall causing damages to the carpet, etc. We are consulting a landscape expert who has suggested several alternatives including a "french drain" combined with another pipe which will take the water from the gutter down spouts and carry it to the street.
I am uncorfortable about the french drain since I have a hard time picturing the perforated pipe taking the water away from my foundation.
Can you shed some light into this? What other alternatives are available.
I have seen a system consisting of connecting PVC canals with grids on top which I think could do a good job carrying the water from alongside the house to the street? Any thoughts or suggestions? Why is the french drain uses as opposed to a ditch with grids on top? Is is economical reasons?
I will appreciate your inputs. None of these improvements are inexpensive and us and the neighbors would like to make the decision which will fix the problem for good.
