Dumpster Pads, Drive-Thru Lanes & Heavy-Load Exterior Concrete: A GC & EC Guide for Retail Projects in Middle Tennessee

Retail and restaurant sites look straightforward until the first heavy truck shows up.

Dumpsters get serviced by front-load trucks. Delivery vehicles cut corners. Drive-thru lanes see constant turning and braking. And a year later, the same areas start showing the same problems:

• Cracking and spalling at joints

• Settlement at trench crossings and utility boxes

• Ponding that turns into ice in winter

• Broken edges where trucks ride the curb

• Patches around handholes/pull boxes that fail again

Why Retail Sites Fail in the Same Places

Most retail failures are not “mystery concrete issues.” They’re predictable load + water + subgrade problems concentrated in a few zones:

• Dumpster pads and approach lanes

• Drive-thru lanes (especially tight turns)

• Delivery routes and loading areas

• Transformer pads and service areas

• Crossings where trenches run under pavement/flatwork

These areas see higher wheel loads, more turning forces, and more water exposure than the rest of the lot.

The GC/Owner Reality: Heavy-Load Concrete Is a Scope Decision

If the plans treat the entire exterior the same, the site will still behave differently.

A durable retail site usually requires intentional “upgrades” in the high-stress zones, such as:

• Increased thickness

• Better base preparation

• Reinforcement choices that match the load

• Joint layout that works with truck traffic

• Drainage details that keep water out of joints and subgrade

GC takeaway: If you don’t design for the dumpster truck, the dumpster truck will redesign it for you.

Zone 1: Dumpster Pads (Where Concrete Gets Abused)

Dumpster pads fail because the loads are high and repetitive, and trucks often stop, turn, and lift in the same footprint.

Common failure patterns

• Edge spalling where wheels ride near the pad perimeter

• Joint deterioration from leachate/water intrusion

• Settlement at the pad approach

• Random cracking from poor joint layout or late sawcuts

Field planning that prevents it

• Define the dumpster pad as a distinct scope zone (not “same as sidewalk”)

• Confirm truck path and service orientation

• Coordinate drainage so water doesn’t pond at the pad

• Coordinate with enclosure/bollards so trucks don’t climb curbs

Zone 2: Drive-Thru Lanes (Turning + Braking = Damage)

Drive-thru lanes are deceptively hard on concrete because:

• Vehicles brake and turn repeatedly

• Loads are concentrated in narrow wheel paths

• Water and oil exposure is consistent

Common failure patterns

• Cracking at tight-radius turns

• Joint spalling where tires scrub across joints

• Ponding that creates ice and surface wear

Practical guidance

• Treat tight turns as a high-stress zone when planning thickness/joints

• Avoid placing joints exactly where tires scrub the most (when layout allows)

• Ensure base and compaction are consistent—drive-thru failures often start below the slab

Zone 3: Delivery Routes & Aprons (Corner Cutting and Edge Loads)

Delivery vehicles don’t follow striping. They follow the easiest path.

Common failure patterns

• Broken corners where trucks cut turns

• Cracking near curb returns

• Settlement over trench crossings

Coordination that helps

• Identify the real truck path during precon (not the “ideal” path)

• Protect corners with geometry that anticipates turning

• Coordinate curb, gutter, and flatwork elevations so drainage doesn’t push water into the slab edges

The Foundation: Base, Subgrade, and Compaction (Still the #1 Driver)

.

Heavy-load concrete doesn’t forgive:

• Soft spots

• Pumping subgrade

• Poor trench backfill

• Inconsistent compaction

Retail-specific hotspots

• Around grease trap areas and utility corridors

• Near dumpster enclosures (often disturbed by multiple trades)

• Around handholes/pull boxes serving site lighting and signage

GC takeaway: If you’re pouring a “heavy-load” slab on a “light-duty” base, you’re buying future settlement.

Reinforcement: What It Does (and What It Doesn’t)

Reinforcement can help manage cracking behavior, but it doesn’t replace base quality.

What reinforcement helps with

• Holding cracks tight (reducing differential movement)

• Improving load transfer behavior (depending on design)

• Reducing random crack width in some conditions

What reinforcement does NOT fix

• Settlement from poor compaction

• Ponding from bad grading

• Joint spalling from bad joint placement/timing

Practical framing: Reinforcement is a crack-management tool, not a subgrade substitute.

Joints: The Make-or-Break Detail for Heavy-Load Areas

Your joint plan needs to match the traffic.

Common heavy-load joint failures

• Joints placed where trucks brake/turn hard

• Late sawcutting → random cracks

• Poor joint sealing → water intrusion → pumping and spalling

Field practices that help

• Treat sawcut timing as a milestone (especially in variable Middle Tennessee weather)

• Keep panels as square as possible; avoid long skinny panels

• Plan isolation around fixed elements (bases, bollards, pads)

Drainage: Water Is the Multiplier

Water makes everything worse:

• It weakens subgrade when it infiltrates joints

• It increases freeze/thaw damage in winter

• It accelerates joint deterioration

Retail-specific drainage issues

• Ponding at dumpster pads (often due to enclosure geometry)

• Water trapped in drive-thru lanes by curb lines

• Downspouts discharging onto flatwork

GC takeaway: If water can sit on it, it can damage it—especially in high-traffic zones.

EC Coordination: Site Lighting and Utilities Without Creating Future Failures

Electrical scope intersects heavy-load zones through:

• Handholes/pull boxes

• Conduit runs under drive aisles

• Light pole bases near curbs and islands

• Sign power and communications

EC best practices

• Keep handholes/pull boxes out of wheel paths when possible

• Set elevations to the same benchmark used for paving/flatwork

• Backfill and compact in lifts—especially in drive-thru and delivery lanes

• Coordinate pole base locations so trucks don’t clip them (or ride the curb to avoid them)

EC takeaway: A handhole that settles 1 inch in a drive-thru becomes a maintenance problem fast.

Sequencing: When Heavy-Load Concrete Should Be Placed

Retail sites get chaotic late in the schedule. The more trades that cross your finished concrete, the more damage you’ll see.

Practical sequencing guidance

• Don’t pour heavy-load areas until underground is truly complete and verified

• Protect finished slabs from construction traffic that exceeds design intent

• Coordinate striping, wheel stops, and bollards so you’re not drilling and patching later

Red Flags That Predict Early Failure

If you see these, expect cracking/spalling/settlement:

• Dumpster pad treated like standard sidewalk thickness

• No plan for trench crossings under drive lanes

• Handholes placed in wheel paths with minimal compaction control

• Joint layout driven by “looks” instead of traffic

• Ponding accepted because “the asphalt will fix it”

One-Page Checklist

• Identify heavy-load zones: dumpster pad, drive-thru turns, delivery routes

• Confirm real truck paths and turning behavior

• Verify subgrade/base and proof-roll high-risk areas

• Require trench backfill in lifts with compaction discipline

• Coordinate handholes/pull boxes out of wheel paths when possible

• Plan joint layout for traffic; schedule sawcut timing

• Plan isolation around bollards, bases, and fixed elements

• Confirm drainage so water doesn’t pond or infiltrate joints

• Protect finished concrete from heavy construction traffic

How Halemeyer Group Helps Retail Projects Avoid Heavy-Load Callbacks

We help GCs and ECs reduce rework by:

If you’re building retail or restaurant projects in Lebanon, TN or across Middle Tennessee and want a partner who understands how trucks, utilities, and site concrete interact, we’re ready to help.

Conclusion: Build for the Truck, Not the Typical Car

Retail sites don’t fail where cars park. They fail where trucks work.

If you identify heavy-load zones early, build the base correctly, coordinate utilities, and match joint/drainage details to real traffic, you can avoid the most common dumpster pad and drive-thru failures—and protect your closeout.
