Boston Line Pump Concrete for Slabs, Basements & Long Runs
When the ready-mix truck parks on the street and the pour point is a backyard, a basement floor, or a slab tucked behind a building, a ground-level line pump threads rubber and steel hose to wherever the concrete needs to land. Economical, flexible, and the right call for most Boston pours that don't need vertical reach. Boston Concrete sends experienced operators and starts every job with a free on-site assessment.
Choosing a Line Pump: Jobs Where It Outperforms Every Other Option
A line pump sits at ground level. Hose sections connect end-to-end and snake from the pump truck to the pour point, whether that's a rear-yard patio slab in Somerville, a basement floor in Cambridge, or a foundation pour on a tight Back Bay lot where the truck can't get within chute distance. The hose bends around fences, threads through gate openings, and drops through window wells. No boom required, no street closure for outriggers.
The economics follow the equipment: a line pump costs a fraction of a boom pump to mobilize, and for any pour that stays at or near grade, the output rate is more than adequate. Boston Concrete recommends line pump as the starting point for every ground-level concrete placement. Boom pump enters the conversation only when the pour point is several stories up or when a specific obstacle demands aerial clearance.
Basement floor pours are a particularly strong fit. The hose feeds through a walkout door, a window opening, or a bulkhead and delivers concrete directly to the slab area below grade, eliminating the awkward chute angles and manual wheelbarrow runs that slow a pour and tire a crew. See our residential basement floor work, review concrete cost guide figures, or check the full concrete pumping service list. For pours that do need height, boom pump service is the next step.

How it works
From Truck to Slab: How Boston Line Pump Pours Get Done
Site read and hose routing
Before the pour date, we walk the site (or review drawings) to map truck parking, identify the pour points, and plan the hose path. We note any tight corners, grade changes, or openings the hose must pass through, and confirm the route is clear of obstructions the crew cannot work around.
Pump truck arrival and line assembly
The pump truck positions at the planned spot. Hose sections are coupled together on the ground, run along the planned route, and connected to the pump outlet at one end and the placement nozzle at the other. The operator checks all couplings before priming.
Prime the line, start the pour
A grout slurry coats the inside of the hose to prevent concrete from sticking and blocking. Once the line is primed, the ready-mix truck feeds the hopper and concrete flows continuously to the placement crew. The operator adjusts pressure and flow rate to match the crew's finishing pace.
Washout and pack-up
When the last yard is placed, a cleaning sponge is pushed through the hose with water or compressed air, flushing residual concrete into a washout area. Hose sections are broken down, loaded, and the site is left clean. The written ticket documents volume pumped and time on-site.
When to choose line
Concrete Slab or Foundation Pour? Line Pump Is Usually the Answer
Think through the pour: the truck parks on the street or in the driveway, and the concrete needs to travel 40, 80, or 150 feet to reach the forms. A line pump handles that distance at a cost that keeps the project budget intact. The hose can be extended in sections to cover longer runs, and the operator manages pressure so the mix arrives at the nozzle in the same condition it left the drum.
Concrete slabs, foundation walls, footings, retaining wall pours, and basement floors all fall squarely in line pump territory. The equipment is compact enough to set up on residential streets without lane closures, and the setup time is short enough that a morning pour can be finished and the truck gone before noon traffic builds on Commonwealth Ave or Beacon Street.
When the scope grows to include upper-floor placements or a pour point that a hose simply cannot reach by ground routing, the job moves to boom pump. For the concrete supply itself, our ready-mix concrete service coordinates delivery timing with the pump schedule. Contractors who supply their own placement crew can also look at pump rental options. Questions about what a specific pour needs? The concrete FAQs cover common scenarios, and the estimate process guide explains what we measure on-site.
Hose length, basement access, pricing and when line beats boom.
Hose can be assembled to substantial lengths depending on the pump's pressure capacity and the concrete mix being placed. Most residential and commercial pours fit easily within standard line length; we confirm reach during the site assessment.
Yes, often the best option for basement placement. The hose can be run down a window opening, through an exterior door, or through a basement walkout to deliver concrete directly to the basement floor area without chute access.
Usually yes, significantly cheaper. The equipment cost is much lower and the setup is simpler. For projects within line pump's capability (ground-level reach), it is almost always the better value.
Clear the planned hose route, identify any sharp turns the hose cannot handle, and have the placement crew positioned. We confirm the prep details when booking.
Typically a setup fee plus hourly rate. Line pump rates are lower than boom pump rates reflecting the lower equipment cost. The quote covers expected pour duration; longer pours bill additional time.

What Boston Contractors Say About Their Line Pump Service
Line pump for a backyard patio that the truck could not reach by chute. Hose run through the side gate, no boom needed, way less than a boom would have cost. Right tool, right price.
