As you say the soil in Pakenham isn't that reactive and usually hasn't got enough swell to lift a double storey back to it's original level but sounds like you done the right thing and were patient. Re: 7 year old house, slab movement, what sort of fix? 9Dec 29, 2014 7:12 am How close was the tree to the house? Re: 7 year old house, slab movement, what sort of fix? 10Dec 30, 2014 1:02 pm StGeorgeBuild How close was the tree to the house? About 2.5 meters distant, estimated to have been planted when the house was built so about 7 years old. After it was called the problem, I did research (it was a wattle) and found a number of reports of wattles causing similar issues. No proof it was at fault, except that the cracks have closed up again and we have not done anything else. As the issue had been there for some years (there was evidence of prior patching before we bought the house), there isn't much else I can point to as a factor. Land settled May '14.

About 2.5 meters distant, estimated to have been planted when the house was built so about 7 years old. The type of tree, its probable age and the distance from the house should have been mentioned in the opening post! The immediate answer then would have been to remove it plus some subsoil remedial advice. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.

Re: 7 year old house, slab movement, what sort of fix? 12Jan 05, 2015 6:23 pm SaveH2O JimmyL I would be ringing a reputable structural engineer ASAP and getting on top of it. Nothing anyone says on here (no offence) is going to fox the problem. There are a couple of steps that you could also consider doing but No. 1 is a must do. 1. Treat the area around the trees with a soil wetting agent and if the trees are growing in a grassed area, remove the grass and apply a good thick mulch (but not up to the trunk) and regularly water this area. You should also buy a rainwater tank and harvest several downpipes. The tank would then supply gravity fed drip hoses that are under the mulch and coil away from the trees. What would be the appropriate degree for the water moisture to be reached? it might be hard to reach the defined ideal statue.

I know so much more now! Land settled May '14. Building the PD Hoffman39: 5/11=site start, 13/11=slab pour, 26/11=frame complete, 10/12=roof on, 12/12=bricking started.

Trees need fairly regular deep watering but if the tree is too close to the house, it will suck the surrounding soil dry by a process known as matric suction. I had assumed that the tree was further away and that watering the tree would lower the matric suction in that area as an interim measure to prevent the situation worsening. 3in1 Supadiverta.
