Enright Asphalt builds reinforced concrete dumpster pads for commercial, multi-family, and industrial properties across Denver and the Front Range. Garbage trucks weigh up to 60,000 pounds when fully loaded. That kind of concentrated weight destroys asphalt in a season or two. A properly built concrete dumpster pad handles those loads without rutting, cracking, or deforming, and it resists the hydraulic fluid and oil that leaks from collection trucks.
We’ve been pouring commercial concrete in the Denver metro for over 30 years. We hold an A+ BBB rating and our crews build dumpster pads to the specifications that garbage collection companies and local codes require. You get a pad that passes inspection, supports the equipment, and lasts the life of your building.
Why Asphalt Fails at Dumpster Locations
Dumpster areas are the highest-stress spots on any commercial property. A front-loading garbage truck pulls up, drops steel forks into the dumpster, lifts several tons of waste overhead, and dumps it into the truck bed. The front axle absorbs the entire weight of the truck plus the lifted dumpster. That concentrated load sits in the same exact spot every pickup day.
Asphalt can’t handle this. The surface softens in Denver’s summer heat, and the repeated point loading creates depressions, ruts, and eventually potholes in the collection zone. Hydraulic fluid leaking from the truck’s lift mechanism dissolves the asphalt binder on contact, accelerating the breakdown. Most asphalt dumpster pads in Denver fail within 2 to 4 years. A 6-inch reinforced concrete pad in the same location lasts 20 to 30 years.
Protect Your Lot, Reduce Your Maintenance Costs
A failed dumpster pad doesn’t just look bad. The potholes and ruts around the dumpster spread into the surrounding parking lot. Water collects in the depressions, freezes, and widens the damage into adjacent asphalt. What starts as a local problem at the dumpster becomes a lot-wide maintenance issue.
Installing a concrete pad stops this cycle. The pad contains the heavy loads to a surface designed for them, protecting the rest of your parking lot from collateral damage. For property managers tracking maintenance budgets, a one-time concrete pad installation eliminates the recurring cost of patching and replacing failed asphalt at the dumpster location every few years.

Dumpster Pad Specifications
Dumpster pads aren’t standard flatwork. They need heavier concrete, more reinforcement, and a larger footprint than most property managers expect. Here are the specifications we follow:
Thickness
Six inches is the minimum for dumpster pads. We recommend 8 inches for properties serviced by front-loading trucks or where roll-off containers are used. Standard 4-inch concrete, the thickness used for sidewalks and light-duty parking, will crack under garbage truck loads within the first year. The extra thickness distributes the concentrated weight and prevents structural failure.
Reinforcement
A double rebar grid is the standard for dumpster pads. We typically use #4 (half-inch) rebar on 12-inch centers running in both directions, supported on chairs to keep the steel at mid-slab height. This creates a concrete-and-steel matrix that handles the concentrated loads without cracking. Wire mesh alone is not sufficient for this application.
Concrete Mix
We pour 3,500 to 4,000 PSI air-entrained concrete for dumpster pads in Denver. Air entrainment is essential because the pad sits outdoors and takes the full force of Colorado’s freeze-thaw cycles. The microscopic air bubbles give freezing water room to expand inside the slab, preventing the internal cracking that destroys non-air-entrained concrete in cold climates.
Pad Dimensions
The pad must be large enough for the dumpster plus clearance on all sides. For a standard 2 to 3 cubic yard dumpster, a minimum pad of 10 feet wide by 10 feet deep is typical. For 4 to 8 cubic yard dumpsters, 12 feet wide by 12 feet deep is the minimum. Two-container setups need wider pads. We also extend the pad 10 to 15 feet in front of the dumpster opening to support the collection truck’s front wheels during the lift operation. Without this approach apron, the truck destroys the surrounding asphalt.
Bollards
Two steel bollards filled with concrete should be installed at the rear of every dumpster pad, spaced about 4 feet apart and centered behind the container. The bollards prevent the dumpster from being pushed into the building wall, fence, or enclosure during the collection truck’s approach. They rise 3 to 4 feet above the pad and extend below the slab into concrete footers for stability.
Dumpster Pad Sizing Guide
| Dumpster Size | Minimum Pad Width | Minimum Pad Depth | Approach Apron |
| 2 to 3 cubic yards | 10 feet | 10 feet | 10 feet in front of opening |
| 4 to 6 cubic yards | 12 feet | 12 feet | 12 to 15 feet in front of opening |
| 8 cubic yards | 14 feet | 12 feet | 15 feet in front of opening |
| Two containers side by side | 16 to 20 feet | 12 feet | 15 feet in front of opening |
| Roll-off container (20 to 40 yards) | 12 to 14 feet | 40+ feet (length of container) | Clear straight approach for roll-off truck |
These are starting points. Your waste collection provider may have specific requirements, and local codes may add additional specifications. We verify the applicable requirements before building.
How We Build Dumpster Pads
Here’s our process:
- Coordinate with your waste hauler. We confirm dumpster size, truck type, access approach, and any specific pad requirements from the collection company before we start.
- Remove existing pavement. We saw-cut the perimeter, break out the old asphalt or concrete, and haul the debris to a recycling facility.
- Prepare the sub-base. We excavate to the required depth, grade the subgrade, and install 4 to 8 inches of compacted crushed stone depending on soil conditions. In Denver’s clay soils, a solid, well-compacted base prevents settling that would crack the pad from below.
- Set forms and reinforcement. We set forms to define the pad edges and approach apron, then install the double rebar grid on chairs. Bollard sleeves are set in position at this stage if bollards are in the scope.
- Pour concrete. We use 3,500 to 4,000 PSI air-entrained concrete at 6 to 8 inches thick. The crew places, levels, and finishes the slab. We score control joints to manage shrinkage cracking.
- Install bollards. If specified, we set concrete-filled steel bollards into the footers at the rear of the pad.
- Cure. The pad needs a minimum of 7 days before the dumpster is placed and at least 7 days before a collection truck drives on it. Full design strength is reached at 28 days.
- Grade transitions. We grade the connection between the concrete pad and the surrounding asphalt so water drains properly and there’s no lip or gap between surfaces.
Most single-dumpster pads take 2 to 3 days of active work. Multi-container enclosures with walls and bollards may take 3 to 5 days.

Frequently Asked Questions
How thick does a concrete dumpster pad need to be?
Six inches is the minimum. We recommend 8 inches for pads that handle front-loading garbage trucks, which can weigh 60,000 pounds when loaded. The pad also needs double rebar reinforcement, not just wire mesh. Standard 4-inch sidewalk-thickness concrete will fail under these loads within the first year.
How big should the dumpster pad be?
The pad needs to be large enough for the container plus clearance on all sides. For a standard 4 to 6 cubic yard dumpster, that’s at least 12 feet by 12 feet. You also need an approach apron extending 10 to 15 feet in front of the opening to support the collection truck’s front wheels during the lift. Without the apron, the truck destroys the surrounding asphalt.
Why not just use asphalt for the dumpster area?
Asphalt softens in heat and dissolves on contact with hydraulic fluid. Garbage trucks apply extreme concentrated loads in the same spot every pickup day. Most asphalt dumpster pads in Denver fail within 2 to 4 years. Concrete handles the weight, resists the chemicals, and lasts 20 to 30 years.
Do I need bollards on my dumpster pad?
Bollards are strongly recommended. They prevent the dumpster from being pushed into the building, wall, or fence when the collection truck approaches. Two bollards at the rear of the pad, spaced 4 feet apart, provide adequate protection. Some municipalities require them.
Can you replace a failed asphalt pad with concrete?
Yes. This is one of our most common dumpster pad projects. We remove the failed asphalt, rebuild the sub-base, and pour a reinforced concrete pad sized for your container and collection truck. The new concrete pad eliminates the cycle of repairing the same spot every year.
How long before the dumpster can be placed on the new pad?
Wait at least 7 days before placing the dumpster on the pad and 7 days before allowing a collection truck to drive on it. Full concrete strength is reached at 28 days. Placing heavy loads too soon risks cracking the slab before it has cured properly.
