However I partly disagree with the next bit of advice because with 150mm rebates, the ground under the 100mm slab and its 50mm sand bed equals the rebate level for raft slabs, and so there may well be no slab edge to inspect when you think about it - perhaps a little for waffle pod slabs. The thing to keep clear of termite attack are the weep holes. Paving and garden and soil must be below these holes or it is an open invitation to termites and this entry point is outside the treated area. The important thing with salinity is to separate the brackish water from the slab with the underlay turned up to ground level as was the rule for all raft slabs until about 1994 I believe. That simple thing should be sufficient, but the taped joints in the underlay must be well done and the concretor must tape up around all pipe penetrations really well and there must not be any puncture holes caused by sloppy workmen. So all up it may be advised to have this secondary safeguard as well as a more durable slab discussed at length. Leonardo_23 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 9853 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 13091 I don’t think so as the floor area over 300 square meters then it is class 3…. 12 17935 |
