Browse Forums Building A New House 1 Oct 20, 2023 12:26 pm We are planning to build a house on a 500m2 5m sloping block. So, trying to cut/fill to create a flat single level slab.. What is the maximum height/depth of a Drop Edge Beam of a slab. Just trying to avoid other retaining solutions and just use the concrete slab edge. Does this image from AS2870 Fig3.5 page36 mean maximum depth is 1500mm?

Does this image from AS2870 Fig3.5 page36 mean maximum depth is 1500mm? rks Most concretors and engineers we have consulted don't like going over 1200mm as a maximum. And even then, depending on your ground conditions the engineers will typical want a brick/strip footing over 1000mm. It also comes down to the weight of your structure as well, ie what your external walls are constructed from. I think technically you can do 1500mm if your concretor is willing, but you need to find a willing one.

Re: Drop (Deepened) Edge Beam maximum depth/height 4Oct 21, 2023 8:27 am I had a similar issue with my sloping block. I overcame it by doing 2 DEB's to the ground floor. Each build site is different as is each owners budget so there are Pros and Cons to adding an extra DEB to the slab design like I have done. Check out my build thread here - https://forum.homeone.com.au/viewtopic.php?f=31&t=102241 and a couple pics below. Hope this info helps.

The distance between my DEBs varies from 4.1m at the narrowest to 8.1m at the widest. Hi all. I have a drop edge beam down the left side of my house. Across the front the drop edge beam is approx 1m on the left and fade to normal ground level on the right… 0 6415 You need to refer back to the structural engineering footings and slab design for edge beams depth. The depth on reactive clay doesn’t necessarily depend only on bearing… 1 8683 Thanks again for this information. If you do hear anything different, would be great to know 4 34399 |
