How far can concrete be pumped?

What's normal on real jobs

Boom pumps handle their own distance — whatever the arm reaches, up to ~60+ m on the biggest trucks. Line pumps routinely run 30–100 m of hose on residential and small commercial work, and specialist setups with steel pipeline push concrete hundreds of metres horizontally or up high-rise towers. If your pour is a long way from truck access, you don't need a miracle — you need a company that plans the pipeline properly.

What actually limits distance

Friction: every metre of line adds resistance, and every bend adds the equivalent of several metres more. Vertical beats horizontal for effort — one metre up costs roughly three to four metres sideways in pressure. Mix: harsh, dry or gap-graded mixes jam long lines; a proper pump mix with the right slump flows. Pump: bigger machines produce more pressure. The company will balance all three — your job is only to tell them the true distance and height honestly, before pour day.

Long-distance pours: what changes

Expect steel pipeline instead of rubber hose for the main run (less friction, safely handles the pressure), possibly a larger pump or a second pump relaying, priming with grout to lubricate the line, and more setup time — which is why long runs are quoted, not winged. A blocked line 80 m in is an expensive way to learn the mix was wrong, so good operators talk to the batch plant directly on big-line jobs.

Quick answers

Can concrete be pumped uphill or to a second storey?

Yes — vertical pumping is routine. Two storeys is an everyday job for either a boom or a well-set line. The pump just needs enough pressure and the line needs securing on the way up.

Does long-distance pumping damage the concrete?

No — properly pumped concrete arrives fully mixed and workable. If anything it stays more consistent than concrete that's been barrowed and re-handled. Only a badly designed mix or excessive delays hurt quality.

Is there an extra charge for long hose runs?

Usually — many companies include a standard length (say 20–40 m of line) and charge per extra metre, plus a line hand if the run needs one. It's on the docket as 'extra line', so ask when booking.
