It's weird isn't it. floating slabs. There is often some cast in steel columns and the stairs tie in but generally the whole conc suspended slab is floating on the bricks! I suppose an earthquake here wouldn't be a good thing!

Well you've sold me in Portugal we use block and beam which is very effective on old stone houses, but I have a small timber deck to replace that joins my pool to a terrace and I am going to poor a slab now to do the job instead of block and beam.

Hey mate, I can’t quite tell in the video but did you use normal chairs for the reinforcing? I’ve got a project coming up with the underside of the slab becoming the finished ceiling downstairs, having a hard time coming up with a way to properly suspend the reinforcing. Do you have any ideas?

If you’re doing an off-form ceiling you want full plastic chairs. Don’t use the steel ones as they leave dents in the soffit and you will see the tips of some of them.

Nice video! What would it look like if a suspended floor was supported on both leaves of a cavity wall? Can you describe it?

@bmformworkconcreteconstruc9783

2 жыл бұрын

yes this can be done but the cavity on external walls prevents moisture entering the home, it also insulates. but when we do this we put down flashing (thin galvanised steel) to cover the cavity.

Do you create any special joint seal or spacer for slabs between different rooms/spaces?

Nope all connected. When we do units there will just be a separation between units. Apartments will be one big slab though.

@@bmformworkconcreteconstruc9783 just curious to know the reason why is this pipe not going straight through the slab downwards to the lower level? Instead it is bent 3-4 times within the slab with 90 degree joints. in case these joints do leak or break due to the expansion/contraction of concrete, wouldn't the leak cause rain water seepage into concrete and cause destruction?

I’m thinking of not to use wood sheets to do my houses concrete slab. It is much to expensive if you use it only one time. In Germany we use “slab - blocks”. I can’t find them here in Panama so far. Maybe I have to use something else instead.

@@IvanChepanovvankata87 I noticed the way you guys build when I travelled Europe. I thought it was mostly done to speed up the building process and add the brickwork after. Sometimes we do this here. To answer your question, we don't have earthquakes, also the walls are actually quite strong, some have steel rods in them, and often they will have a steel column inside the wall. So they do take measures to prevent lateral movement I guess. We also naturally have resources here for making cheap quality bricks so I think that is the main factor. Bricks are the cheapest way to build here.
