Re: Wall cracks, building footpath as per CSIRO BTF18 35Jan 07, 2023 5:55 pm If you want to use an agi pipe then it will have the same effect and create excessive water where ever it slopes to and ends. Normally they are connected to a pit which then transfer the water into the stormwater system which goes to a legal point of discharge. Re: Wall cracks, building footpath as per CSIRO BTF18 36Jan 07, 2023 6:05 pm groundzero This is an option rather than a agi pipe but if you don't want to connected it to the storm water system then where ever it discharges (where the plastic sub surface channel ends) water will collect there and it could become very wet and soft so it should be away from any structures and not discharging into neighbouring properties. It will really depend on how your block slopes, block size, soil type etc. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Yes, that's what we're concerned about - the water pooling at the end of the plastic, and the ground in that area becoming very soft/damp. We have H2 clay. We are on a couple of acres. The land slopes from the West to the East, so we get all of the surface water from our neighbour on the West. We get the most water on the West side of the house. On the other sides, the surface water has a nice fall away from the house. Installing an agi pipe all the way around the perimeter and then connecting it to the stormwater seems like a big (and expensive) task. We would like to avoid it if we can. But I can see how creating a fall for the first metre around the house (like the builder advises) is only likely to create a further problem.
