Browse Forums Building A New House 1 Apr 21, 2015 8:28 pm Wondering if anyone can shed some light on this one for me. I notice that some builders use the floortech type systems for upstairs slabs, and others use suspended concrete slab. Is there generally much difference in cost? What are the pros and cons of each? My guess is that the floor tech option would be a bit quicker in terms of overall build time...? Thanks Re: Cost & benefits of floortech vs suspended concrete slab 2Apr 21, 2015 9:45 pm There will be pluses and minuses. It is quicker and you can run services underneath. It maybe a little more noisy. I guess I will see when I get my house as I am having floortech Keep to hear from others although my bed is made. Cheers Mark Re: Cost & benefits of floortech vs suspended concrete slab 3Apr 24, 2015 4:20 pm I'm also trying to determine this now as the builder I'm leaning towards uses Floortech. I just want to know the truth and not get too clouded in particular builders opinions (mainly cause their company either does or doesn't do it). From what I can work out through basic research; - it's quicker to install saving a few weeks on build time - it allows much more flexibility with electrical and plumbing, particularly after the house is built - it's still reasonably sound proof although being a 'thinner' slab on top of the floortech system, you may hear more noise than a traditional 200mm reinforced slab But my questions are, how thick is the Floortech slab? Is it 100mm or still 200mm? The builder I have some plans with is allowing 4c for the whole system between floors (my GF ceilings will be 31c and the UF starts at 35c) and the Floortech framework looks at least 200mm deep, so I assume the concrete thickness is between 100mm and 150mm maybe (assuming 4c is about 340mm)? APG told me it was only 20mm thick but I don't trust their honesty in that they are one of the builders who doesn't use it. I have a building industry friend who says the system is used extensively in the eastern states like Melbourne. But then they also build pretty much all brick veneer construction and Floortech may be more suitable over there cause of that. Anyone else know the thickness of the Floortech concrete? Re: Cost & benefits of floortech vs suspended concrete slab 4Apr 24, 2015 4:28 pm Uh, not sure if floortech is what we have, I just call it a truss flooring system? But anyway if that's what we're talking about, we have it and the slab concrete is 85mm thick Our build thread: https://forum.homeone.com.au/viewtopic.php?f=31&t=70984 Re: Cost & benefits of floortech vs suspended concrete slab 5Apr 24, 2015 7:37 pm Yep the slab is 85mm thick which is about half a pour slab. Sound wise I believe the cavity in the 4 courses is insulated. Definitely not 20mm. I did check on the website but the thickness is not mentioned. I have checked with the builder as was told as above. Lots if builders in Wa use floor tech. Cheers Mark Fair Trading can issue orders to rectify and complete but once the matter goes to NCAT these orders are automatically vacated. You will have to terminate contract and sue… 21 29679 How are you doing Ben? Extremely interested in hearing what you are doing or plan to do! 12 15113 The concreter will take and reuse. In my case I bought structural LVLs and scraped them back and used them as joists. 1 5150 |
