Trying to find out the what difference of a Compaction Report and a Dynamic Cone Penetrometer Test. They appear to be similar but one is supplied to the engineer by the developer and with that and the soil report they commence to design the slap and foundation. Question is are the tests the same or is a soil compaction report and the DCP test different. Thanks for all of your help. Re: Soil Compaction. 2May 19, 2020 9:17 am Does either state safe bearing load/pressure, depth, un/consolidated fill, soil moisture content,settlement, etc,etc? I usually do a penetrometer test before and after site works, BTW, you need to ask for the additional information in writing hth Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: Soil Compaction. 3May 19, 2020 9:35 am StructuralBIMGuy Does either state safe bearing load/pressure, depth, un/consolidated fill, soil moisture content,settlement, etc,etc?

Our land was water logged and was considered fill and we have since the first week had movement in the house, it has been confirmed we have heave so we are now going back through all the tests to see what was, wasn't and should have been done.

Re: Soil Compaction. 6May 19, 2020 11:45 am Penetometer test is not exactly the best measure for site compaction, they usually use it to test soil bearing capacity as part of geotech testing. Usually they use nuclear densometer to measure compaction as this is the most reliable testing, so you should have a proper compaction testing report specifying density ratio (it generally should be higher than 95 or whatever specified in your engineering documentation).

Sounds more like tree drying damage from what you have said Re: Soil Compaction. 8Sep 05, 2020 4:12 pm There are no trees or have even been trees on the property. I am not sure whether Perth has its own way of doing things in regards to this. Most of Perth has class A (sandy soil), except for some areas near rivers or hills. 2 13100 We were lucky in that our old house was so small (86 square metres) compared to the new house, they were able to take enough readings around the old backyard house before… 8 37147 DIY, Home Maintenance & Repair I'm in WA and our sandy soils make drainage a bit easier but this is what I'd be doing.
