Concrete pumping, explained properly

Plain-English guides to concrete pumping: how pumps work, boom vs line, sizing, site prep, hiring, careers and machines. Written by the industry, for the industry.

Pumping basics

What concrete pumping is and how it works

  • What is a concrete pump and how does it work? — A concrete pump is a machine that moves liquid concrete from the truck to the pour through steel pipes or rubber hoses — using powerful hydraulic pistons. It replaces wheelbarrows and cranes, placing concrete faster, cleaner and exactly where it's needed.
  • Boom pump vs line pump — which one do you need? — Use a boom pump when the truck can park near the pour and reach it through the air — big slabs, high work, open sites. Use a line pump when access is tight and the concrete has to travel around or through obstacles — backyards, basements, renovations.
  • What size concrete pump do I need? — Measure from where the truck can park to the furthest point of your pour — then add a safety margin, because a boom's working reach is 2–3 m less than its advertised size, and it needs height to unfold. Most house jobs land between 28 m and 47 m.
  • Types of concrete pumps: boom, line, trailer, city and static — Five main types: truck-mounted boom pumps (reach through the air, 20–60+ m), line pumps (hose along the ground), trailer/static pumps (towable workhorses for long runs and high-rise), city pumps (compact truck + line combo for tight streets), and separate placing booms for towers.

Can you pump…?

Distance, height, access and mix questions

  • How far can concrete be pumped? — Routinely: 150 m horizontally or 30–60 m vertically with standard gear — and far beyond that with the right pump and pipeline (the world record is over 600 m straight up). For a normal Australian site, distance is almost never the problem; planning the line is.

Hiring a pump

Booking, site prep and what it costs

  • How to prepare your site for a concrete pump — Five things before the pump arrives: solid level parking for the truck, clear overhead (no powerlines within exclusion zones), a washout spot, confirmed concrete delivery times, and access for the line or boom to the pour. Ten minutes of prep saves an hourly-rate machine standing idle.
  • How to choose a concrete pumping company — Pick on reliability, not the cheapest hourly rate: a pump that's 45 minutes late costs more than any rate difference when concrete's on the road. Check they carry the right machine for your access, real insurance, and a track record — then lock in the details in writing.

Working in pumping

Operators, businesses and careers

  • How to become a concrete pump operator in Australia — Get your PB class high-risk work licence (concrete placing boom), a construction white card, and time on the tools as a line hand. Most operators start as labourers, learn the pump from the ground, then licence up — 6 to 18 months from first day to first solo pour.
  • How much do concrete pump operators get paid in Australia? — Licensed boom pump operators typically earn $35–$55+ per hour ($75,000–$120,000+ a year with overtime); line hands and offsiders around $28–$38 per hour. Owner-operators with their own boom can gross $250,000–$500,000+ a year — before the machine's costs.
  • What makes a good concrete pump operator? — Calm under pressure, obsessive about setup, smooth on the sticks, and honest on the docket. A good operator protects the crew from the boom, protects the pour from the pump, and protects the client from surprises — the machine is the easy part.
  • What makes a good line hand (and pump labourer)? — Anticipation. A good line hand moves the hose to where the pour is going, not where it is — keeps the line kink-free, watches the operator's signals, and makes the clean-up disappear. It's the trade's proving ground, and the fastest route to an operator's seat.
