Patrick Posted July 5, 2021 Posted July 5, 2021 Looking to screed my block and insulation floor. I know some of you...looking at you, @Russell griffithsARE not keen on liquid screed . But with 100m from nearest lorry access and 13cubes of screed, I really dont want to wheelbarrow dry screed into the site. So option left is liquid screed pumped. The challenge is, nobody in my area supplying that. They do pump concrete but say I'm too far out for liquid screed . I thought liquid screed is just a sloppy mortar (sand and cement)mix... is it not? Cause I was thinking about ordering just that ... concrete made with sharp sand , they are able to pump that ...what's the disadvantage of using this?
nod Posted July 5, 2021 Posted July 5, 2021 You can pump sand and cement screed also Most semi dry used on commercial jobs is pumped up to each floor Might be a good option 100 m is fine 1 1
Mr Punter Posted July 5, 2021 Posted July 5, 2021 The firms that do the install normally have the pump etc and buy the products from a variety of suppliers. They should be able to supply what you want. 1
Russell griffiths Posted July 6, 2021 Posted July 6, 2021 Do you not need a structural topping to go over your insulation? i thought you did, or have you changed the floor build up. As nod said you can pump the traditional screed, my lads where fantastic and would cover your area. I would allow £22 a m to supply and lay yours, maybe a bit more if area is small, as they need to allow for travel and setting up the pump. The lads I used came from Swansea and will travel to you. 1
ToughButterCup Posted July 6, 2021 Posted July 6, 2021 Our screeding company provided a checklist for us to go through before they came. That form had a question about distance from delivery point for the wagon to the floor to be screeded. I was surprised to find out that, as @nod says above 100m is fine - unless thats 100m vertically I suppose. ? 1

Top man. I knew I did it right to cc you in. Also much clearer now . Apparently I dont need screed . It s my english - stupid foreigner. I need reingorced concrete topping on top of my block and insulation floor . Gonna buy a powerfloat and tackle the smooth surface myself . Wish me luck. ?
Russell griffiths Posted July 7, 2021 Posted July 7, 2021 Just hirer one you will only need it for one day. get the edges shuttered up to the correct height then hire a spin screed. You will need a concrete pump and four guys. How wide is your place.

Only issue is that it takes a few hours before pumped concrete is dry enough to powerfloat ...

Patrick Posted July 11, 2021 Author Posted July 11, 2021 I am , as always, grateful to have experienced advise from this forum (and @Russell griffiths as the most experienced simply due to age ?) Pumped reinforced Concrete is the way . Pumping at 8.00 Helicopter from 16.00 Should be a breeze
IanR Posted July 11, 2021 Posted July 11, 2021 It does depend on temperatures, we we're power-floating from about 10:30 (while still pumping in) after a 07:00 start on a warm May pour.
Patrick Posted September 3, 2021 Author Posted September 3, 2021 No Powerfloating on this one now- we can t get anyone who even halfway decent knows what they are doing... so need to do the best with the knowledge i can have on the day and that is oldschool slab . as straight as possible... Will need a tiled floor after i guess -wish me luck ?

Patrick Posted September 4, 2021 Author Posted September 4, 2021 6m . we can get it fairly level with traditional methods. just not on a powerfloated level -
Dave Jones Posted September 5, 2021 Posted September 5, 2021 you cannot get a vehicle closer than 100m ? Long way to carry the shopping.
