Had one of these on-site last week for a 100m3 foundation pour.

Never worked with one before, but what a great machine! I guess it is only as good as it's operator - but we had the entire 280 linear metres (100m3 of concrete) in by 12.30!

Best part? It was only circa £400 for the pump. Well cheap in my opinion.

Had a quote down south for pumping concrete a maximum of 20 linear meters for £240 no vat, this covered the minimum charge of 5 hours.

Only a diy'er so be gentle but several questions not relating to concrete pumping
1) What are the footings for (weird pattern), would it have been better to make it more shallow and one big pad
2) How do you get excavators to cross trenches like the one in the back of the photo, the ground round here is so soft you would just drive in to it even when partly full of concrete?

I would not have spoilt it with concrete/building its beautiful, like a piece of art!!

The footings are for a childrens centre for the local council. Full of toilets, small rooms. Bit of a weird layout, I agree!

The whole oversite was 'topped' off with 100-125mm of stone, this helped to consolidate the ground and allow the machines over the filled footings. You'll see the dumper was driven over them quite a bit with no ill effect

2500t reduce dig and cart away.....

and add the stone layer to the site. Compact with 100 roller.

and then installing the foul and stormwater drainage systems - connecting into the existing nearby public sewer and storm water holding tank

very impressed with the excavation on those footings dave. Amzed how the little tiny squares of soil left didn't collapse in on the trenches.

I love a big dig out job, though round here its not easy getting rid if the spoil :(

Bins laid on concrete base as directed by the independant BI

Pipework laid, bedding sprinkled in from large grading bucket on machine.

Pipework then set to correct falls, foul runs tested and verified by Site Agent/BI and then pipework runs covered with approx 125mm 10mm single size chipping.

Not the way I'd do it, be we took over that drainage run from another crew. Aslong as the end "product" is the same, then no harm done.

Yeah, it was a great dig - so glad we have had a nice dry spell over the past 3 weeks. We had virtually no caving-in of those trenches.

The stone oversite was a great idea, I like that way of doing things. Keeps things tidy etc - a clean site is a happy site!

Getting rod of sub-soil round here is easy - although we have lost two or three useful local tips as they are now full. There are plenty of large construction projects locally that are now wanting subsoil etc - a free tip! :)

Yeah, we do all sorts really - back to a bit of the black stuff Thursday and Friday, makes a change!

nice work there dave
we used a pump recently to get 16m3 over the roof of a bungalow
i am sure it was the biggest pump summat like 70 m reach and it was bout £500 +VAT for the job
only problem was the pump has a box with about 5 barrows of concrete to get rid of at the end which they didnt tell us about and we had to tip it on the garden
cheers LLL :)

Yeah, the retained concrete in the pump can be a suprise!!!!

Cleaning out the pump wagon is a fair old job, too. Did you see the foam tennis ball being used?

yeah he sucked it up 3 times
the driver/operator was telling us that you can still drive them on a normal licence as they are classed as a special vahicle(although at 150K a pop the firm would have to trust you
i think the one we had was a lot bigger,there was no agitator just a load of pipes and a big box,all the locals come out for a nose so it was fun,but the driver reckons that they were and are very very dangerous when they go wrong (i.e. blockages) he said his firm had 1 fatality and 2 blokes crippled in the last 10 years==not good
