Can a Concrete Pump Work Between Two Houses with Narrow Side Access?

By PumpX Team · 17 October 2026

If your backyard is only reachable through a gap between two houses, you might assume you can not get a pump in. In fact, narrow side access is one of the situations line pumps were designed for. Here is how it works and how to prepare.

The pump stays on the street, the hose goes through the gap

The heavy equipment (ready-mix truck and pump) parks on the street or driveway, wherever it is safe and stable. The hose is the only thing that goes through the narrow gap. A standard concrete hose is quite slim, so a side passage of under a metre can be enough, if it is clear of obstacles. The pumping company can tell you what clearance they need.

What to check before you book

• Width and clearance. Measure the narrowest point and the height of anything overhead, like eaves, pipes or gates.
• Obstacles. Meter boxes, air conditioners, bins, gas bottles, steps, sheds and garden beds all need moving or protecting.
• Surface. Hose is heavy when full. Uneven ground, loose pavers or steps can cause the hose to shift. Lay boards if needed.
• Distance. Longer runs need more hose, which usually costs more.
• Street access. Even if the gap is fine, the truck must be able to park close to the front of the gap.

Which pump suits?

If you are unsure, send photos of the gap, the street and the pour area to a couple of pumping companies and ask what they would use. A good operator can usually tell from the pictures.

Protecting walls and the neighbours

Concrete hose in a tight passage can scrape paint, break plants and knock fences. Cover the walls with ply or old carpet, tie up loose items and clear the path. Tell the neighbours: the noise starts early, the street will be busy and some might need to move cars.

Remember that a pour done through a passage is slower than a pour from a boom, because the placer has to work with a hose end and may need extra people to move it. Allow for that in your time estimate, as pump time is charged by the hour.

What about cost?

Line pumps are generally cheaper per hour than boom pumps, but set-up, hose length and clean-up can add up. Residential line pump jobs in Australia commonly run in the low thousands of Australian dollars depending on region, minimum hire and hose runs. Prices elsewhere vary in local currency. The rate calculator can help you see how hours and travel add up.

Practical day-of tips

1. Clear the passage the day before.
2. Have a person at the street to guide the trucks.
3. Have one person at the pour end holding the hose, one finishing and one coordinating.
4. Keep a water supply handy for washing off splashes.
5. Plan where the washout will go so it does not end up on a neighbour's property or down a stormwater drain.

When the gap is really tight

If the passage is so narrow that a person has to turn sideways, ask the operator whether smaller-diameter hose or a different route is possible. Sometimes the best option is not through the gap at all, but over a low roof or along a neighbouring driveway, with the neighbour's permission. Get that permission in writing if you can, and agree on repairs if anything is damaged. If a pump truly can not reach, a power barrow, a small conveyor or splitting the pour into smaller loads may still do the job. Whatever you pick, confirm the plan with your pumper and concrete supplier before the day.

Key takeaways

• Narrow side access rarely stops a pump. A line pump hose can pass through gaps a person can squeeze through.
• The heavy equipment stays on the street; only the hose goes in.
• Measure the gap, clear obstacles and protect walls.
• Send photos to pumping companies so they can recommend the right machine.
• Tell the neighbours and plan washout in advance.
