Every concrete pour starts with the same question: how do we get the mud from the truck to the forms? If you’re a contractor working anywhere in North Central Florida, you’ve probably weighed hiring a boom pump against a line pump. The answer depends on your project, your site, and how much concrete you’re moving. We run both types of equipment out of Lake Butler, and we see contractors make the wrong call more often than you’d think.
This breakdown covers what each pump does, when to use it, and how the costs compare so you can make the right decision before the ready-mix trucks show up.
What Is a Boom Pump?
A boom pump is a truck-mounted concrete pump with a robotic arm (the boom) that unfolds and extends over obstacles to place concrete exactly where it needs to go. The operator controls the boom from a remote, positioning the end hose with precision while the pump pushes concrete through the pipeline at high volume.
Boom pumps are built for speed and reach. They can extend over houses, across trenches, and into areas that would be impossible to reach with a wheelbarrow or even a long hose run. On a commercial pour, a boom pump can move 100+ cubic yards per hour. That kind of output turns a two-day pour into a half-day pour.
Common Boom Pump Applications
- Commercial foundations and elevated decks
- Multi-story pours where concrete needs to go up and over
- Large residential foundations (3,000+ sq ft)
- Pool decks and patios with limited ground access
- Any pour where the truck can’t park close to the forms
- High-volume pours (20+ yards) where speed matters
What Is a Line Pump?
A line pump (also called a ground pump or trailer pump) pushes concrete through a steel or rubber hose that runs along the ground from the pump to the pour location. There’s no boom arm. The hose is laid out manually by the crew, routed around corners and through tight spaces.
Line pumps move concrete slower than boom pumps, but they go places a boom truck physically can’t. Tight residential lots, backyard pours, interior slabs with low overhead clearance. If you need to snake a hose through a gate and around a building, a line pump is your tool.
Common Line Pump Applications
- Residential driveways and sidewalks
- Backyard patios and pool fills
- Interior slab work and fill pours
- Small to mid-size pours (under 20 yards)
- Sites with tight access, narrow gates, or low overhead lines
- Grout and specialty mix pumping
Boom Pump vs Line Pump: Side-by-Side Comparison
| Factor | Boom Pump | Line Pump |
|---|---|---|
| Reach | Extended-reach boom extends over obstacles and structures | Ground-level hose, laid manually along the route |
| Output (yards/hr) | High (100+ cubic yards/hr typical) | Moderate (15-30 cubic yards/hr typical) |
| Setup time | 15-30 minutes (outriggers + boom deployment) | 10-20 minutes (hose layout) |
| Setup space needed | Large footprint for truck + outriggers | Compact, fits tight lots and driveways |
| Best for | Commercial, large residential, elevated pours | Small residential, backyard, interior, tight access |
| Hourly cost | Higher hourly rate | Lower hourly rate |
| Total cost on big pours | Often cheaper per yard due to speed | Higher per-yard cost on large volumes |
| Concrete types | Standard ready-mix (3/4″ aggregate or smaller) | Ready-mix, grout, flowable fill, specialty mixes |
How to Decide: 5 Questions to Ask Before You Book
1. How Many Yards Are You Pouring?
Volume is the first filter. Under 10 yards, a line pump almost always makes sense. The lower hourly rate keeps your total cost down, and a smaller pour doesn’t need the speed of a boom. Over 20 yards, the math starts shifting. A boom pump’s higher output means your ready-mix trucks aren’t sitting in line waiting, and your finishers aren’t standing around. On a 50+ yard commercial pour, a boom pump can save you hours of labor across your whole crew.
2. What Does Your Site Access Look Like?
Walk the site before you call. If there’s room for a large truck with outriggers (roughly 25-30 feet of width), a boom pump is an option. If you’re working behind a house, through a 3-foot gate, or on a lot where power lines and trees block overhead access, a line pump is the safer bet. In older Florida neighborhoods with mature oaks and tight lot lines, line pumps are often the only realistic choice.
3. Does the Concrete Need to Go Up or Over Something?
This is where boom pumps earn their keep. Second-story pours, elevated pool decks, foundations behind retention ponds. If there’s a vertical or horizontal obstacle between the truck and the forms, a boom arm solves it without extra hose runs, clamps, and manual labor.
4. What’s Your Concrete Mix?
Standard ready-mix pumps well through both. If you’re pumping grout, flowable fill, or a specialty mix, check with scheduling first — line pumps are more particular about the mix design than boom pumps, and a quick conversation about slump and aggregate size before pour day prevents clogs and rejected loads.
5. What’s Your Budget?
Boom pumps have a higher hourly rate. No getting around that. But cost per yard tells a different story on bigger jobs. If a boom pump finishes your 40-yard pour in two hours and a line pump would take five, the boom may actually cost less overall, and your labor crew definitely costs less. For a detailed breakdown, see our guide on concrete pumping costs.
Cost Comparison: Boom Pump vs Line Pump
Both boom pumps and line pumps bill hourly, with a minimum fee per job. The hourly rate for a boom pump runs higher than a line pump because the equipment cost is significantly greater. A boom pump truck can cost $500,000+, while a line pump is a fraction of that.
Here’s the part most contractors overlook: a boom pump’s speed can offset the higher rate. If you’re pouring 30 yards, a boom pump might finish in 45 minutes of active pumping while a line pump takes 2+ hours. Factor in your finisher crew’s hourly rate and the cost of keeping ready-mix trucks on standby, and the boom pump may come out cheaper on total project cost.
At Croft Concrete Pumping, we bill hourly with a minimum, and that’s it. No fuel surcharges. No primer fees. No hidden fees. Call us at (386) 623-1782 for an estimate on your specific project, and we’ll help you figure out which pump is the right fit.
Florida-Specific Considerations
Sandy soil and soft ground. Florida’s sandy lots can be a problem for heavy boom pump trucks, especially after rain. If the ground is soft, the truck may need mats or a stabilized pad for the outriggers. A line pump is lighter and less likely to sink or shift.
Summer storms. Florida’s afternoon thunderstorms can shut down a pour fast. If you have a large volume to move and a narrow weather window, a boom pump’s speed gives you the best chance of getting the mud placed before the sky opens up.
Water table pours. Below-grade work near Florida’s high water table often requires pumping into forms that are partially surrounded by standing water. A boom arm lets you place concrete from above without running hoses through the wet zone.
When to Call a Pumping Service
If you’re not sure which pump you need, just call. A good pump operator can look at your site plan, yardage, and timeline and tell you the right answer in five minutes. That’s part of the job. We’d rather steer you to the right equipment before pour day than show up with the wrong pump and waste everyone’s time.

Frequently Asked Questions
What is a boom pump used for?
A boom pump is used for placing concrete at a distance or over obstacles using a truck-mounted articulating arm. It’s the standard choice for commercial pours, large residential foundations, elevated decks, and any job where concrete needs to reach over or past structures that block direct access from the truck.
How far can a boom pump reach?
Boom pump reach varies by the size of the truck and its boom configuration. Smaller boom pumps can reach around 80-100 feet, while larger units extend well beyond that. The right reach depends on your pour location relative to where the truck can safely set up. Your pump operator can assess site access and recommend the right boom size for the job.
When should I use a line pump instead of a boom pump?
Use a line pump when you’re pumping a smaller volume (under 15-20 yards), when site access is too tight for a boom truck and outriggers, when you’re working through narrow gates or in backyards, or when you’re pumping grout or specialty mixes. Line pumps are also the more economical choice for straightforward ground-level pours with easy truck access.
What are the pros and cons of boom pumps vs line pumps?
Boom pump pros: fast output, long reach over obstacles, efficient on large pours. Boom pump cons: higher hourly rate, larger setup footprint, needs stable ground for outriggers. Line pump pros: lower hourly rate, compact setup, handles tight access and specialty mixes. Line pump cons: slower output, ground-level reach only, less efficient on large volumes. The best choice depends on your project’s volume, access, and budget.
