Delivery trucks, semis, and heavy equipment back into loading docks thousands of times per year. The pit collects water and road salt. The apron edge takes steel-plate abuse. Standard concrete fails in five years. We build loading dock slabs engineered for the actual truck loads, with steel edge protection, proper slope away from the pit, and integrated dock-leveler embeds. Free written estimate on every project.
Why Loading Dock Concrete Fails Faster Than Parking
A parking lot spreads truck loads across a wide surface. A loading dock concentrates them into a small footprint where the rear wheels land, over and over. Add freeze-thaw cycles, salt pooling at the pit, and steel dock plates dragging across the leading edge, and a standard parking-spec slab spalls and fails in five years.
The fix is engineering. We pour dock slabs thicker than the surrounding lot, with extra rebar at the wheel-load zone, a steel edge angle cast into the leading edge to absorb dock-plate abuse, and an apron sloped to drain away from the building. When existing docks have failed, we cut out the damaged section and rebuild to the correct spec, not the original undersized one.
This same engineering discipline applies to our commercial sidewalk work, our parking lot pours, and every site concrete project. Each surface gets the spec it needs, not a one-size-fits-all approach.

How it works
Building a Loading Dock Slab in Detroit
Assess truck loads and site conditions
We measure the pit footprint, confirm the truck types and weights, identify any existing dock-leveler or equipment requirements, and plan the apron slope and drainage path before any forms go down.
Prepare pit and apron base
The pit is excavated to depth, the apron subgrade is compacted, gravel base is laid, and any pit drainage lines are run. Forms are set to the engineered dimensions with the slope already built in.
Set reinforcement and embeds
Rebar is tied to spec with extra steel at the wheel-load zone. Steel edge angles are positioned at the leading edge with embed studs welded in place. Dock-leveler anchor bolts and channels are set at the coordinates the supplier provides.
Pour, finish, and harden
Concrete is placed and consolidated into the forms. The apron surface is finished with a broom or trowel for grip. A hardener is applied to the high-wear areas. The slab cures per spec before the dock leveler is installed.
When repair is the right call
Fixing a Failed Loading Dock Means Finding the Root Cause
Most failed loading dock concrete is not a slab problem. It is an engineering problem. The original dock was poured too thin, the steel edge angle was omitted, the apron was sloped backward into the pit instead of away. Patching the spall without fixing the cause means the dock fails again in two years.
We assess every failed dock by asking what went wrong on day one. If the slab is sound and only the edge is spalling, we cut out the edge, add the steel angle that should have been there, and pour a new edge section. If the whole apron is undersized or reverse-sloped, we recommend full replacement with the correct engineering. Our equipment pad and ADA ramp work follows the same principle: fix the root cause, not just the symptom.
Slab specs, steel edges, dock-leveler embeds, drainage and when to repair vs replace.
Because they take concentrated repeat loads at a single point (the truck rear-wheel landing spot), steel-on-concrete abuse from dock plates, and concentrated water/salt at the pit. A parking-lot spec slab fails inside five years at a loading dock; the dock spec is different by design.
It protects the leading edge of the dock from the steel dock plates that drag across it during loading. Without it, the concrete edge spalls within a year of regular dock-plate use. The angle is cast into the pour with embed studs that anchor it permanently.
Yes. We coordinate with the dock-leveler supplier to set their embeds (anchor bolts, channels) at the right positions before the pour. Adding them after the pour is messy and rarely fits as cleanly; integrating them up front is the right way.
Always away from the pit. The slope drains meltwater and rain off the apron toward the parking lot or a catch basin, never into the pit which catches enough water on its own from the open dock door. Reverse-sloping into the pit is the most common failed-dock pattern we see.
Depends on the cause. Localised spalling at the edge with a sound slab beneath, sectional repair plus a steel edge retrofit works. Systemic failure from wrong original engineering (too-thin apron, no reinforcement, reverse slope), a new dock is the honest answer.

What Detroit Operations Say About Their Loading Docks
Replaced a dock that had failed at six years. New apron engineered for our truck loads, steel edge angle cast in, sloped away from the pit. Three years in, zero spalling. Built to last this time.

★★★★★
They identified the original dock was reverse-sloped into the pit, which was the cause of the failure. New dock slopes away. Pit stays dry, edge intact, trucks back in without abuse.

Warehouse Director, Warren
★★★★★
Coordinated with our dock-leveler supplier to set the embeds in the new pour. Leveler dropped in cleanly afterward, no improvisation needed. Real trade coordination.
Y. I.
Industrial Facility Manager, Ann Arbor
★★★★★
Edge repair on three docks instead of full replacement. They were honest that the slab beneath was sound, only the edge needed work. Added steel angles to all three, no spalling since.
