Two small pours, same yardage, opposite answers
Picture a small pad beside a shop building with a hard drive running right up to the forms. A truck backs in, the chute swings out, gravity does the placing and nobody pays for a machine. Now picture the same few yards behind a house, through a gate, down a set of steps, in a back yard a loaded truck has no business entering. Same volume, same mix, same crew, completely different day.
That is most of the answer to this question. Yardage is the number people bring to the phone. Access is the thing that decides it. A line pump is not an upgrade you buy once a pour gets big enough. It is a way of covering the last stretch when the truck cannot cover it, and that stretch is just as impassable at two yards as it is at twenty.
What does not get smaller when the pour does
Here is the honest reason small pump jobs run proportionally dearer, and it is worth understanding before you ask what one costs. A fair share of the work happens whether there are two yards or twenty. The trailer still tows in and gets parked. The route still gets walked and the hose still gets laid. The line still gets primed with slurry before any concrete goes down it, because nothing travels a dry hose. At the far end the line still gets cleared and the hopper still gets washed out.
So the machine time per yard is at its worst on the smallest jobs. That is not a reason to never pump a small pour. It is the reason we will tell you plainly when a small pour does not need one, because on those jobs the arithmetic is not close.
The small pours we tell people to skip it on
Owning the machine is exactly why this list belongs in writing. When gravity can do the placing, nothing else needs to.
- A pad or slab the truck can back straight up to, with the chute making the forms on its own
- A few barrow loads to finish out a corner the chute nearly makes, which is just part of a normal pour
- Steps, sidewalk sections, small pads and post footings, where the carry from the truck is short and flat
- Hand mixed work, where no ready-mix truck was ever part of the plan
The small pours that are pump jobs the moment you look at the walk
Then there is the other half. A couple of yards for a basement floor, placed inside walls already up and backfilled against. A short run of stepped footing down a bank behind a garage. A small patio behind a fence with one gate into the back yard. A pad inside a shop with a door and no other way in. None of those are large pours and none of them are chute pours.
The test that beats every rule about yardage is a walk you can do yourself in two minutes. Go stand in the spot a loaded truck could really sit, rather than the spot you would like it to sit, then walk that route to the forms. Short, level and clear means you do not need anybody to bring a machine. If the walk goes around the house, past a gate, down a slope or over something already finished, volume stopped being the thing that decides it.
Small pours for other crews, and what one comes to on paper
Builders and concrete crews hit this from the other side. There is a small awkward pour on the schedule, no pump in the yard, and it is not worth reorganising a week over. We do the pumping for you on those. Our pump, our operator, our hose hand, on your pour and your date. The pump does not get handed off to anybody else to work, so nobody on your payroll has to learn it for one morning a year.
As for what a small pour comes to, that gets settled on a free written estimate rather than by a rule of thumb, because two small pours with different walks are not the same job. On our own work the pumping sits inside one price for the whole job, so there is nothing separate to weigh up against it. There is a workmanship warranty on the finished work, and the exact terms are set out on that same written estimate.
