Re: Who is responsible for pooling around a house? 5Jan 31, 2021 11:46 pm Get some stakes, next time it rains and the yard floods, wade around and find the deepest spots put a stake in each of the deep spots. This will be were your yard gullies should be installed, either dig the trenches yourselves or get a plumber in for a quote. But you will still need to locate the low points even if getting the job done by a contractor. We are Expert Consultant's, and we are here to help.

But you will still need to locate the low points even if getting the job done by a contractor. So levelling the land with soil wouldn't make a difference? Is it because the water would just sink to the original soil level? We will take your advice -thank you. Re: Who is responsible for pooling around a house? 7Feb 01, 2021 10:07 am Most Councils require surface storm water water run off disposal plans that have impervious soils, hardscaping, paving. These require falls and discharge away from the house? I always recommend a min 300mm pad to raise the house with gradings away to gullies, check your site plan levels and ffls. hth Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: Who is responsible for pooling around a house? 8Feb 01, 2021 10:33 am The water is currently ponding and can't get away, filling the site to hide the problem won't resolve the problem but will most likely create abnormal moisture conditions in the soil causing heave. Finding your low spots means you can install yard gullies that will be effective in draining the surface water. You can add fill of top soil after you deal with the problem. StructuralBIMGuy is also correct in that you should have positive fall out from you slab edge (full perimeter) google CSIRO BTF18 Foundation Maintenance it takes a pretty common sense approach in explaining this issue.

I always recommend a min 300mm pad to raise the house with gradings away to gullies, check your site plan levels and ffls. hth Our site plan doesn't seem to say anything other than the fact that there should be a fall of approx 1m length away from the slab. What does ffls stand for?

Could you please tell me what exactly gullies are? Our neighbour's property is quite raised (he raised it with a lot of soil) so now all the water comes to our property (the land also naturally slopes from his property towards our house). We have a paddock adjacent to the house (behind the photograph shared) that is almost completely flooded when it rains. It's that water that is moving close to our house. Would a spoon drain along the neighbour's fence line (all the way to the LPOD) help capture and then divert the water? Re: Who is responsible for pooling around a house? 11Feb 09, 2021 8:30 am FFL = Finished Floor Level This means the finished height of the slab to your internal living area, your porch, your alfresco/patio, your garage relative to the pad level. Pad level was your start point, they cleared the vegetation/soil off the build area and then built the home up from this level. The BCA requires the builder to address stormwater & surface water drainage associated with the construction of the house. The slab edge should not have water ponding next to it as this water will cause the clays in the soil to expand due to absorption of the water. Your yard photo shows water siting out from the slab edge, this would suggest that there is positive fall out from the slab edge We are Expert Consultant's, and we are here to help.

Although there does appear to be some fall in the photograph shared, there is no fall around the other sides of the house. The builder never made an effort to protect the slab (insufficient slope around the house, no temp down pipes, no surface drainage) -we have inspection reports confirming all of that. Re: Who is responsible for pooling around a house? 13Feb 11, 2021 8:59 am Think of the water as lazy because it always goes downhill. At the moment it stops at the lowest point it can get to and pools where you don't want it. You need to have some way of moving it to where you want. Surface drainage would help as well as sub-surface drainage. I had a property with a adjacent acreages and the water flowed towards my home until I created some drainage uphill from my home to keep it moving away and into surface drains installed by the builder. Is there somewhere you can redirect the water to? This certainly doesn't look good. I would be engaging with an independent inspector to have a look at this.
