It is the first question most people ask before booking: will the pump actually reach my pour? It is a fair concern, because the answer decides whether a job is simple or a real headache.
The short version is that a concrete pump can move concrete a long way, but the exact reach depends on the pump type, the setup and the site itself. Easypump Concrete Ltd runs pumps across London, Hertfordshire, Bedfordshire, Buckinghamshire, Essex and Northampton, and we plan reach on every job before we arrive.
This guide explains how far and how high can a concrete pump deliver concrete, what changes those numbers, and how we work it out for your site.
What Reach Actually Means With a Concrete Pump
Reach is not one figure. It splits into three parts that work together on every pour:
- Horizontal distance along the ground from the pump to the pour
- Vertical height up a building or structure
- Total pipeline length from the pump to the pour point
These trade against each other. Every metre you go up uses more of the pump’s effort than a metre along the ground, so a pump that pushes concrete a long way flat will not reach as high vertically. When Easypump Concrete Ltd quotes reach, we look at all three together rather than a single headline number.
How Far Can a Line Pump Deliver Concrete?
A line pump pushes concrete through a ground-level hose, and it is the workhorse for most domestic and small commercial jobs. On a clear, flat route it can move concrete a long way, often well over 100 metres, by adding sections of hose.
The real distance depends on the conditions in front of the pump. The main factors are:
- Hose length: more sections extend the run, within the pump’s limits
- Ground-level routing: flat, straight runs reach further than twisting ones
- Number of bends: every corner adds friction and shortens effective reach
- Pipe diameter: narrower lines build more resistance over distance
- Pump power: a stronger pump holds pressure across a longer line
For most back gardens, side returns and ground-floor pours, a line pump has plenty of reach. The limit is rarely raw distance and more often how many tight bends the hose has to take.
How High Can a Boom Pump Reach?
A boom pump uses a folding arm mounted on the truck to lift concrete up and over obstacles. This is what you need when the pour is at height or on the far side of a building.
Booms come in different sizes, and the reach climbs with the arm length. As a rough guide:
- Smaller booms, around 20 to 24 metres: single and two storey work, tight urban sites
- Mid-size booms, around 28 to 36 metres: multi storey pours and larger slabs
- Large booms, 42 metres and up: tall buildings and long horizontal reach from one setup
The headline figure is the vertical reach, but the same arm also gives horizontal reach. That means a boom can drop concrete into a spot well away from the truck without any ground-level hose at all.
Line Pump vs Boom Pump Reach Compared
Both pumps move concrete, but they solve different access problems. The choice usually comes down to whether your route runs along the ground or has to go up and over something.
Here is the quick comparison:
- Line pump wins when the route is along the ground, through gates and gardens, even over a fair distance
- Boom pump wins when the pour is at height, over a roof, or behind a building the hose cannot pass
- Line pump is simpler to set up and often the better fit for domestic work
- Boom pump clears obstacles a line pump would have to route around
On many jobs a line pump is all you need. The boom earns its place the moment the ground route is blocked or the pour climbs above the first floor.
Factors That Affect How Far Concrete Travels
Reach is not just about the pump. The concrete itself, and a few site details, change how far the mix will travel before it becomes hard to push.
The main factors are:
- Mix slump: wetter, more workable mixes flow further than stiff ones
- Aggregate size: larger stone is harder to pump over long runs
- Pipe diameter: wider pipe lowers friction and helps distance
- Bends in the line: each bend acts like extra metres of straight pipe
- Vertical climb: going up draws on the pump far more than going along
- Temperature: hot or cold conditions affect how the mix behaves in the line
Because of these, two jobs with the same measured distance can behave very differently. Easypump Concrete Ltd factors all of this in when we plan a pour.
Vertical vs Horizontal: The Rule of Thumb
The single most useful thing to understand is that height costs far more reach than distance. Pushing concrete up a building works against gravity the whole way, while pushing it along the ground does not.
A common working rule is that every metre of vertical lift uses several metres of the pump’s horizontal capacity. So a pump rated for a long flat run will reach only a fraction of that height straight up. This is exactly why a tall or over-the-roof pour often calls for a boom, even when the straight-line distance looks short.
Real Site Examples
It helps to see how this plays out on actual jobs. The setup changes with where the concrete has to go, not just how much.
A few typical scenarios:
- Back garden slab: ground-floor pour down a side return, line pump routed through the gate
- Second floor pour: concrete lifted to a first or second floor, mid-size boom doing the climb
- Over-the-house pour: rear garden blocked by the building, a boom reaches over the roof from the front
- Long driveway run: flat but distant pour, line pump with added hose sections
In each case the deciding factor is the obstacle, whether that is a wall, a roof or plain distance. Match the pump to the obstacle and the pour is straightforward.
How We Plan Reach Before Your Pour
Good planning removes the guesswork on the day. Before any booking, Easypump Concrete Ltd looks at the access route, the pour location and any obstacles between the truck and the concrete.
A few photos or a short video of the site make this far easier, since we can see the gates, parking, height and any bends the line will face. From that we choose the right pump, work out the setup and confirm the reach is comfortable rather than borderline. Our operators are trained and experienced, so the plan holds up once we are on site.
Planning the Right Pump for Your Site
Reach is rarely the thing that stops a job. With the right pump and a bit of planning, concrete can travel a long way along the ground and high up a building, even on sites that look impossible from the gate.
The key is matching the pump to your access: a line pump for ground-level runs and a boom pump for height or obstacles. To check the reach for your pour, call Easypump Concrete Ltd on 01582 550287 or email admin@easypump.co.uk, send a couple of site photos, and we will confirm the right setup and a clear quote.
