Re: UNDERHOUSE DRAINAGE 5Jun 04, 2012 10:59 pm There is agi pipe along the outside of two sides of the house. I can't get access to the other two sides due to concrete and/or decking. As the house slopes down at the front that's where the water runs to. As I can't put agi along the outside back of the house I was putting it under the house along the back to at least stop water sitting under the house and/or pooling near the brickwork at the front. Re: UNDERHOUSE DRAINAGE 6Jun 05, 2012 7:56 am hazza ago I used 90 ml stormwater pipe 10 yrs ago for the same reason slotting it half way around the pipe using a angle grinder cutting (nicking it) at intervels all the way along the pipe then tapped into existing ground water pipe (stormwater) without using a sock but using 10 ml gravel instead with a capped off flushing point if it ever silts up . I use this system to, behind retaining walls that i build simply because i only want to do it once and never again. Its never failed me or anybody else iv'e told.

If so, I would have thought that these would catch whatever they can and that the downhill side would drain away from the house. The main agi is on the side of the house which slopes down towards the front. The other agi pipe is on the downhill side to stop water pooling there. So theres still one uphill side that has no agi and hence the water goes under the house and sits. The house not only slopes back to front but right to left as well so the water tends to pool in the lowest corner under the house. Thanks for everyones help if anyones owns a midget you can come help anytime 2 6165 I would find out how deep your clay base is and depending on the depth install a cut off drain which is more than a normal agi drain.
