A standard concrete mixer truck can reach about 18 feet from its tires to the point of discharge using its built-in chute. That’s the baseline, and for many residential pours like driveways and garage slabs, it’s enough. When you need to place concrete farther than that, your options expand significantly: boom pumps can reach over 150 feet, conveyor trucks stretch past 100 feet, and line pumps can push concrete hundreds of feet through hoses laid on the ground.
Standard Chute Reach: About 18 Feet
Every ready-mix truck comes with a folding metal chute attached to the rear. The chute uses gravity to slide wet concrete from the drum to your forms, and the maximum practical distance is roughly 18 feet measured from the truck’s tires to where the concrete lands. Most trucks include one or two chute extensions that bolt on to stretch the reach a few extra feet, but the concrete still needs enough slope to flow. If the ground between the truck and your pour site is flat or uphill, even 18 feet can be optimistic.
Chute pours work best when the truck can back up close to the forms. That’s a bigger ask than it sounds. A fully loaded mixer carrying 10 cubic yards weighs approximately 66,000 pounds (about 26,000 for the truck and 40,000 for the concrete). Soft, muddy, or freshly graded ground may not support that weight, and tight lots with fences, overhead wires, or narrow gates can keep the truck too far from the pour area. If you can’t get the truck within 18 feet, you’ll need one of the methods below.
Boom Pump Trucks: 30 to 170 Feet
A boom pump is a truck with a robotic, multi-section folding arm that extends over obstacles and delivers concrete through a pipeline built into the boom. These are the trucks you see on commercial job sites towering above buildings. They come in a wide range of sizes. Smaller units with three-section booms reach around 30 to 60 feet, which is common for residential foundation walls and second-story pours. Mid-range four-section booms reach roughly 80 to 120 feet. Large five-section models, like a 52-meter unit, offer a vertical reach of about 168 feet and a horizontal reach of around 155 feet, with a net reach from the front of the truck of about 148 feet.
Boom pumps also reach downward, which matters for basement pours, retaining walls on slopes, or any situation where the pour site is below the truck. A large boom pump can place concrete more than 120 feet below its setup point. The boom rotates and articulates, so the operator can swing it over fences, around trees, and into tight spots that no truck could drive to.
The trade-off is cost. Boom pumps are significantly more expensive to hire than a simple chute pour, and they require space to set up stabilizing outriggers. For a residential job, expect to pay several hundred dollars or more just for the pump, on top of the concrete itself. But if your pour is large enough (say, 5 yards or more) and the site is hard to access, a boom pump can save hours of wheelbarrow labor and produce a better result because the concrete arrives faster and more consistently.
Line Pumps: Hundreds of Feet on the Ground
A line pump (sometimes called a trailer pump or ground pump) pushes concrete through a network of steel pipes and rubber hoses laid across the ground. Instead of reaching over obstacles, it goes around them. Line pumps are common for residential slabs, pool decks, and backyard projects where a boom truck would be overkill or can’t fit.
There’s no fixed maximum distance for a line pump, but practical runs of 150 to 300 feet are typical. Longer runs are possible with the right setup. The key limitation is friction: the farther the concrete travels, the harder the pump works. Steel pipe creates much less resistance than rubber hose. Ten feet of rubber hose takes roughly the same pumping effort as 30 feet of steel pipe, so experienced operators run rigid steel pipe for as much of the distance as possible and use flexible hose only at the end where they need to maneuver. Keeping the line as short and straight as possible, with minimal bends, also helps maintain flow.
Line pumps typically handle smaller aggregate mixes, often using 3/8-inch pea gravel pushed through 2-inch to 3-inch diameter hoses. If your project calls for a standard mix with larger aggregate, you’ll want to confirm with the pump operator that their equipment can handle it. Line pumps are generally less expensive to rent than boom pumps and work well for smaller pours in hard-to-reach areas.
Conveyor Belt Trucks: Up to 100 Feet
A telescopic belt conveyor, often called by the brand name Telebelt, is a truck with an extendable conveyor belt mounted on top. The belt carries concrete (or other materials like gravel and sand) outward from a hopper, placing it with more precision than a chute and at distances that rival smaller boom pumps. A large conveyor truck can reach about 100 to 106 feet horizontally at a flat angle, with a net reach beyond its outriggers of roughly 100 feet. The boom rotates a full 360 degrees, giving the operator access to all sides of the truck from a single setup position.
Reach decreases as the boom angle increases. At a 30-degree incline, horizontal reach drops to around 86 to 92 feet. Conveyor trucks are popular for projects that involve placing large volumes quickly, like long sidewalks, commercial slabs, or roadwork, because the belt moves material faster than a pump for certain applications. They’re less common for residential work but worth knowing about if your project is large and the site allows truck access within about 100 feet.
Choosing the Right Method for Your Pour
Your decision comes down to three factors: how far the concrete needs to travel, what obstacles are in the way, and how much concrete you’re placing.
- Under 18 feet with clear truck access: Use the truck’s chute. It’s the simplest and cheapest option. Just make sure the ground can handle a 66,000-pound truck.
- 20 to 100 feet with ground-level access: A line pump is usually the most cost-effective choice. It works well for backyard pours, pool decks, and sites where the path is clear but the truck can’t get close enough.
- Over obstacles or into elevated locations: A boom pump is your best option. It’s the only practical way to place concrete over fences, into upper stories, or down into deep excavations.
- Large-volume flat pours within 100 feet: A conveyor truck offers fast placement with good precision, though availability varies by region.
When you order concrete, tell the ready-mix company exactly how far the pour site is from the nearest spot a truck can park, what’s between the truck and the forms (fences, slopes, buildings), and how many yards you need. They deal with site access questions every day and can recommend the right pumping setup for your situation, often coordinating the pump truck alongside the mixer delivery.
