Browse Forums Building A New House 1 Sep 25, 2021 11:24 pm Looking to put a screed on a new concrete floor which is around 230sqm, part of the floor has electric underfloor heating systems. Which kind of screed would be the best to use? I have heard of Davco Lanko 189 bulk fill screed, they seems very high strength but not sure how many square metres a 20kg bag can cover. The thickness required is around 40-50mm. Re: Screeding question 4Sep 26, 2021 12:21 pm At 40mm you are looking at 9.2m³ of screed. That's basically a 10m tip truck full. A typical sand and cement screed will be the most cost effective. You can get large trucks that mix screed on site and pump it in. It will be much quicker to use this. It's a question of working out the costs for traditional mix on site and barrow in or using a pump truck for a day.

Any ideas how much 9.2m3 would cost? Re: Screeding question 7Sep 26, 2021 7:49 pm tangle88 chippy At 40mm you are looking at 9.2m³ of screed. That's basically a 10m tip truck full.

You'd have to get quotes from tilers. They can do it manually with a mixer and barrows, but obviously that is going to take time to do. If they get a truck in it will be much quicker so you will save on labour but the truck will cost. Just get a few quotes from different tilers and compare. This is one company that does the pump. You can give them a call and get a basic cost for supply. https://www.google.com/url?sa=t&source= ...

We used approximately 5 cubic meters of sand and 1 of cement. We went the traditional route of having our tiler with a team of 6 guys mix the screed on site. Took a full day and cost around $40/sqm or $4000 all up. That roughly works out as a day rate of $300 each plus materials Based on your area of 230sqm at 40-50 I think you would need around 1,150 bags of the Davco to get your 50mm coverage. Bunnings has it at $40/bag therefore materials alone would cost you $46,000. Then you have the labour to mix it and screed. As per chippy's post, give some tilers in your local area a call and get their advice as in your local climate zone they would have experience of people using underfloor heating and would know what works and what doesn't.
