Browse Forums General Discussion 1 Jun 03, 2012 5:14 pm Im currently in the process of removing and levelling out the dirt under my house... Yes it is a long and painful task which must be done as there are low and high spots and the water is just sitting under the house. (I think i now have many fungal diseases growing in different parts of my body ) So, after i sort the levels out i want to put agi pipe around the edges of the house (yes underneath) which will all lead to an external stormwater pipe. Now my question is this.... Can i lay the ag pipe with only a sock on it or would it work much better if i put some rock on top of it and just leave it without any soil on top. I dont have any blue chip but i do have recycled aggregate in abundance so was going to use that on the top of the pipe.... The reason i want to know is that: A) Having to hump blue chip under the house will be painful beyond belief as the crawl space is obviously not condusive to achieveing this. B) The depth im laying the agi pipe is not as deep as i would like so want to sit the agi pipe in the trench and just lay rock on top. Re: UNDERHOUSE DRAINAGE 2Jun 03, 2012 7:55 pm The sock keeps fine grit out, the rock keeps the sock working. I would use both if you can stand it. Why not put the aggy drain outside the building perimeter? @builderforlife Building inspector and passionate about construction When you need an expert to take a look. Re: UNDERHOUSE DRAINAGE 3Jun 03, 2012 8:22 pm The recycled aggregate (concrete and brick) is OK to use. As builderforlife suggested, why not put the agg line outside the building perimeter, which makes more sense.

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.

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 7Jun 05, 2012 9:01 pm When you say you have agi pipe along two sides of the house, are these the uphill sides? If so, I would have thought that these would catch whatever they can and that the downhill side would drain away from the house.

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.
