I'm 100% convinced, that if our state and federal government were serious about housing affordability and building new houses to ease this, they should pay you (and others like you) at least $300,000 a year and give you a dedicated team and unlimited resources to pump out videos on how we construct quality houses in Australia.

hi Buildsum, again, thanks for this great vid. Im wondering two more things about formwork. 1. How to form up a 50mm setdown for a screed in a wet area, and 2. how to form the 45 degree internal angle connection between 400mm deep perimeter edge beams and 100mm slab (in section view), if constructing a timber frame on a slab?
@Buildsum4 жыл бұрын
Hi Sue, the 50mm setdown would be formed up with temporary pegs that would be removed and the holes filled in, after the concrete has been poured and the first screed completed. The 45-degree internal angle is shaped into the ground or the waffle pod. I show this in this video kzfaq.info/get/bejne/Zrudkrel25-Ze6M.html Hope this helps
@suetheron44954 жыл бұрын
@@Buildsum thanks yes it does help - I'l have to get the excavator to shape that in. Im assuming it doesn't have to be exactly 45 degrees - the Engineer did not specify anything about this angle, I just see that the slab needs to be thicker to avoid any shear forces

Hi Grant, You could just nail through the face of the edgeboard into the ledger however that will make pulling it apart hard with the concrete in position so the best idea is to skew nail through the ledger into the edgeboard. Hope this helps.

@Buildsum6 жыл бұрын
Unless you want the footing to come out of the ground I would not worry about the formwork. To keep the excavation as accurate as possible digging by hand is best or if you need to use a machine to dig it with an undersized bucket and finish it off by hand.

Hi Mate, thanks for your comment, look I would say 5 to 10mm at the most depending on the area. Remembering that your frame and or brickwork can't overhang the slab more than 20mm max and your cavity (if you have one) can't be any less then 20mm either I think, you need to be pretty accurate.

Hi Nermin, you would think that it would and if it was water then, of course, it would, however for reasons that I am not exactly sure about, it doesn't. As you say it is probably the density of the concrete that prevents it from overflowing the formwork.

Hi Roger I would only take out all of the top soil until you get to good, compact soil, if this is too deep then you may have to get the slab designed for the soil type. Most soil can be used as fill as long as it is clean, free of organic matter and minimal clay content. There are also products like road base that will compact very well

@Buildsum7 жыл бұрын
Hi Roger Yes, The moisture barrier should go down either under or over the top of the waffle pods before the mesh is installed and termite protection applied around the penetrations in the slab before it is poured. After the slab has been poured additional termite protection is applied to block the cavity
@rogerlz3497 жыл бұрын
THANKS John, for the penetrations of termite protection, is that mean chemical spray on the soil which under the slab? is that spry job has to be done by licensed pest controller and need grab a certificate for CERTIFY? I saw a TERMITE membrane product which will be laid the as same position as moisture barrier on top the infill soil, is this kind product better or cost too high?
@Buildsum7 жыл бұрын
Hi Roger You can spray however all sprays nowadays have a limited life span so unless you can get back underneath the slab to reapply it they are not worth using. Terimesh and similar products have collars that go around pipes to stop termites getting through. Yes, all termite systems must be installed by a licenced installer. Kordon is a combination DPC and Termite barrier which can be used on the penetrations and perimeter the same way as Terimesh but would be very expensive to use as a waterproof membrane under the entire slab

@Buildsum6 жыл бұрын
Hi Scotty, Yes you are correct, some of the confusion comes because you could use 2 or 3 of those terms to describe the same slab, e.g. a slab on ground is all so a monolithic slab, also a raft slab, an on fill slab and a Waffle Pod Slab. this link might also help docs.google.com/document/d/16XNkQf_K3-jrYWroU-YH0-PoRsV5pI0hvEKSbTfkM08/edit?usp=sharing
