Concrete pumping in Northern Ireland? RoI? Use a Dumper Instead?

[mikkymo]

I’m building a double garage / shed at the back of my house which will be 65’ (20m) from the main road with access through a ‘drive through’ garage (door at either end). I need 6m3 of concrete in the new garage base and I will only have 4 people total to do the labour and tamping/levelling/floating, so wheelbarrowing is out. The concrete supplier has told me that they will wait 15 minutes per load, plus 5 minutes per cube, so 45 minutes to get the concrete off the lorry and into the base.

Seems like I have 2 options – dumper trucks or a concrete pump. I can’t see anyone in Northern Ireland who has a concrete pump apart from the huge boom types for commercial builds. Rough cost for one of those is apparently £1000 a day.

Anyone know any companies who pump in NI or ROI for a decent price? Ones who use trailer type pumps? Can they be towed by a car?

If I go for the dumper route, how do I get the concrete close to where I want it, over insulation, DPM and mesh sitting up on stands?!?!?

We use in-line pumps all the time here in Staffs.

Here is a typical invoice...

That's the job alright!

Phoned up FIVE local concrete pumping companies in the Yellow Pages and the lowest quote so far was £480 for a days hire of a 30m boom system. I doubt it would even fit into my street along with the mixer lorry. My curtain twitching pensioner neighbours would have a canary. One guy told me he's been in the pumping game for 15 years and he's never seen a trailer pump in Northern Ireland. Over here we must be good with the wheelbarrows. Maybe I should buy one and hire it out.

Looks like there's a company in Dublin - Easy Pumps Concrete Pumping - which do those trailer type pumps, but no joy getting hold of them yet.

Contacted a supplier of concrete pumps in Ireland and they have sold 2 in the North, both of which are used by piling companies for their own work so not for hire.

So now I'm left with forking out £480 for a boom pump, or 2 dump trucks at £100 a day. Was thinking I could place the rebar into the concrete as I go, in 2' x 2' size sheets? Is there any downside to having lots of sheets rather than a continuous sheet or larger sheets wired together?

How do you drive the dumper on top of 50mm kingspan insulation? Scaffold boards?

Has anyone laid concrete with a dumper truck?

Sounds like you'd be better off getting a couple more bodies in, and maybe, paying the conc. truck a bit of waiting time if necessary. Got to be cheaper than £480.
