Roller striker or twin beam screed

[GB_Groundworks]

To be fair they are cheaper than the time and plant hire I'd allocated to do it they'll stay till it's done they'll even cut the expansion joints, and it'll be done right. No point balls in it up or running rd stressing like feck on the pour day. They want 1 truck every 15mins which Cemex or the local place can do, so think ill support the local lads £74 a cube

I wish haha

When my mate poured the ground floor at MK DON's he gave them a go, it was £1000 for the day, over 1000m2 job, but with the added hassle of having to DPM and steel whilst trying to pour is a pain in the neck. You can't beat screeding by hand!

We'll be laying out the mesh or clipping the feet on, laying the dpm tidying up, sorting the machine pits out pokering them etc we'll be busy. Ill stay with them as well while they finish it, bringing 5 guys, 3 ride on floats,

Tony, I wish mate but I was to cheap on this one wont loose money due to it being our plant and made on the stone but next one ill know and just inc these guys fee on the job

ok... thats why its costing more.

[lutonlagerlout]

money well spent giles getting the proper men in
we got that shuttering guy in before xmas for 2 days and a couple of little things he did and said made all the difference between succeeding and failing
plus your rep is on the line
rock, I wouldnt fancy hand screeding 600m2 :;):

seen lads like your subbie in action, 1000m2 plus pours and there the muts to watch in action. laser leveled and floated by little hovercraft (cant think of a better description). its flatter than a bowling green when their done.

1 truck every 15 minutes ?

I was driving passed a building about 24 years ago and RMC wagons where stacking on the road, there must of been 12 RMC wagons all waiting to pour and being interested in that type of stuff I parked up and walked into the building where I first set my eyes on one of those machine like the photo above, a wagon backed in and it took longer to empty the wagon than it does to level the concrete, I bet its less than 4 minutes to level 6m3 including repositioning the self levelling machine - awesome bit of kit

a couple of years earlier I had poured 176m3 in 2 days using steel road forms and a vibrating beam screed with a power float finish, that machine made my pour a look like a feeble attempt with the speed which it was placed and levelled

We all have jobs that get a bit tight on the old money and time, every day is a learning day!

[GB_Groundworks]

yep as its pumped the pump can only do 8cu in 15 mins, weve got 4 8cu trucks on, guy reckons he'll have the bulk done in 3 hours then jus the fiddle bits rd stantions etc

im pleased, takes all the stress out of us and acutally maybe cheaper on reflection when i add in all the hassle of setting forms perfectly etc hiring a roller or twin beam and the engineer is much more pleased its one continous pour, plus saves on dowling etc. its the future i tell they

[bodgeitandscarper]

I'm interested in learning abit more is there any videos on the net?

[seanandruby]

done a few of those mass, continuous pours and the most important thing is.......the girl in the chuck wagon keeps the food' coming. Lads pored a slab last week 4.pm i came in next morning and they had left powerfloating to me, a struggle as it had been frosty night. They had'nt done the edges, or cleaned the shutters, nightmare to finish. Don't think it'll last, as it started lifting, so who will get the blame. They came back and done a grout mix along the edges, no scabble and no primer, doomed to fail after it's benchmarked .

[GB_Groundworks]

been there done that powerfloating in the dark at 1am using teh digger lights, also gone home tried to catch it early next morning didnt work hence the late one, this is inside a nice warm 20 degress shed with lights so theyll be fine, although canteen shut saturdays but towns only 5 min walk

[mickg]

I totally agree Giles its a better method more cost effective and less chance of anything going wrong on the day

[Brucieboy]

Giles - You've probably got it sorted already, but just in case, has the laser screed company agreed the concrete mix design? - usually via a Mix Design Certificate provided by the concrete supplier. This should confirm cement type, actual cement content, slump etc etc and if an admixture has been agreed. As stated previously, most of the laser / powerfloat guys don't like using a conventional water reducing admixture (lignosulphonate-based WRA) but some do specify proprietary products such as Grace Adva Floor 200 or other particular superplasticisers.

Much better to have full agreement in advance than argue about a problem when it's too late.
