Browse Forums Paving & Concreting 1 Apr 08, 2011 9:43 pm Been wondering how did they build all those little verandas and porches like the ones here on the pics. These houses would be from 45 to 25 years old, approximately. Obviously, they used a brick wall (single or double?? ) and then probably built a suspended slab which spans across the edges of the wall?? Or not?

Re: How do you build this?? 2Apr 09, 2011 6:12 am Ive been under a few of those old houses as a kid, suspended slabs,they used to have tin roof sheets under the concrete and a few brick piers through the center. I remember watching one get poured prolly 20-25 years ago and part of it collapsed. I remember the mad panic of the concretors.

Love that happy sandy colour too!!! Beautiful! Do you know if they are planning to "dress up" (eg. paint or clad with someting) the slab edges? What kind of reinforcement did you have to put into that? Does this sit on sheets like Aiah said? Aiah, were the walls built of double brick? Was there a "logic" (some distance rule) for the piers?

Re: How do you build this?? 5Apr 09, 2011 9:33 pm '72' there is also a strip of timber 'form' under the edge that we were removing when the photo was taken. The edge .. 'brick rendered' retaining wall supports the hardstand. The inside has the same mix but polished and the stones are awesome. Where you are coming from is where you are going to... Re: How do you build this?? 6Apr 09, 2011 9:39 pm Oh, so the top part is the formwork timber?! And you planned for the top of the slab to hang over so that they can then build a brick wall so that the edge would not be overhanging any more?? Awesome! BTW, is there only one layer of 72? Can that really stand to all the weight?? My signature is distracting people from my wise posts ... Re: How do you build this?? 7Apr 09, 2011 9:43 pm No the hardstand is sitting on top of the wall... and that is made of bricks and render. The lip will stay It is not going anywhere.

More than 1 layer of 72?? And (of course ), adding a new question ... how thick is the slab? My signature is distracting people from my wise posts ...

Re: How do you build this?? 12Apr 13, 2011 1:58 am Lex, it's not a suspended slab. As onc said, the front wall is a retaining wall with fill behind then the slab is poured on top of that. With your pictures above, I'd say the top two pictures would be much the same. Often in those old houses they used to use the area under the verandah to chuck all the rubbish from the job to act as fill. Then throw in some sand to level and pour concrete. The bottom picture would definitely be a suspended slab as it has an under croft garage. It will just be a continuation of the main suspended slab.

Our old house also had a little porch like that and we (well, he ) used to crawl into under the house, including that little porch. We even used to have brick vents in there for ventilation, so ours was definitely not on fil. But, can concrete that's not sitting on ground stay put with just one layer of mesh? And are these slabs somehow anchored/connected into that retaining wall / brick wall?? My signature is distracting people from my wise posts ... Re: How do you build this?? 14Apr 13, 2011 10:55 am Hi lex, I think some of the difference is that over here in the Perth we are just about exclusively on sand. That means that our construction is quite different to you guys and your reactive soils. A lot of our older houses were built using limestone blocks for the foundations and then double brick walls sat on top. The internal timber floors were then built inside this. That meant that you have a solid limestone wall around the perimeter and internally that could then be used to fill. They did this for the wet areas inside as well. A non structural verandah like the one's you pictured could probably get away with minimal reo. A proper engineeredsuspended slab has far more steel in it. In fact it doesn't have mesh in it. It has far bigger steel in it arranged in 2 or more layers. If you want to see how much steel goes in a suspended slab have a look at my thread in the OB section. I took some shots of my slab after the steel was tied, there was something like 3.5 tonnes of steel.
