Browse Forums Building A New House 1 Feb 24, 2021 7:33 pm Hi all I have highly reactive clay soils which is causing design issues for my heavy masonry building. Is anyone aware of ability to replace highly reactive clay with sand and having it compacted to achieve a class A site classification? Thanks Re: Importing fill - possible to achieve class A site classi 2Feb 24, 2021 7:48 pm Jgoat Is anyone aware of ability to replace highly reactive clay with sand and having it compacted to achieve a class A site classification? Thanks I doubt you will be able to remove sufficient clay to achieve Class A classification Best you might do is have the Class M reclassified as Class S, tho still a raft/grid footing required.. goodluck Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: Importing fill - possible to achieve class A site classi 3Feb 24, 2021 7:50 pm StructuralBIMGuy Jgoat Is anyone aware of ability to replace highly reactive clay with sand and having it compacted to achieve a class A site classification?

Any idea of how deep I would have to go to achieve Class S? Re: Importing fill - possible to achieve class A site classi 4Feb 24, 2021 7:56 pm Over 1.2m deep, over firm compacted clay, low water table, etc,etc You'll need to find some local engineer to certify it Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: Importing fill - possible to achieve class A site classi 6Feb 24, 2021 10:32 pm alexp79 what is the issue with piering it up? I’m looking to do rock cladding and I understand that this will mean that I will have to do articulation joints each 4.5m and also under and above each of the windows and doors / openings. This means that I’m going to end up with a lot of movement joints which cannot be hidden from downpipes and so we are worried this will ruin the look of the stone cladding If it is class A or S then we can avoid movement joints altogether Re: Importing fill - possible to achieve class A site classi 7Feb 25, 2021 8:51 pm Jgoat If it is class A or S then we can avoid movement joints altogether No Articulation joints on class A or S full masonry.. that's how we build in perth Don't get sucked in on architectural 3D realistic renderings without the 3D engineering and costs or it will come back latter on as a variation...$ticker $hock. Cheers Chris Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs 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 13104 I don’t think so as the floor area over 300 square meters then it is class 3…. 12 17940 The Soil classification has little to do with piers. The purpose of the classing of the soil is to identify the clay content and the "average expected range of movement… 2 9859 |
