Loading Dock Concrete
Loading docks take more abuse than any other concrete surface on your property. RCC builds and repairs heavy-duty dock slabs engineered to withstand semi-truck traffic, forklift loads, and years of impact and abrasion.
Heavy-duty loading dock concrete built to handle constant truck traffic
The Toughest Job for Concrete
Loading docks endure punishment that no other concrete surface faces. Heavy trucks backing in and out, forklifts racing across the apron, pallet jacks grinding over joints, and constant impact from dock levelers and bumpers. Add freeze-thaw cycles, road salt exposure, and diesel fuel spills, and it's no wonder loading dock concrete fails faster than any other commercial surface.
When dock concrete deteriorates, it creates safety hazards for workers, damages equipment, and slows down operations. RCC specializes in heavy-duty dock concrete that's engineered to handle these extreme conditions and keep your operations running smoothly.
Why Loading Docks Fail:
- Repeated heavy impact from truck trailers and dock levelers
- Concentrated forklift wheel loads on thin or undermined slabs
- Freeze-thaw damage from constant water and salt exposure
- Poor original construction — insufficient thickness or reinforcement
- Sub-base erosion from drainage problems washing away support
Our Dock Specifications
Heavy-duty specifications engineered for loading dock environments.
Slab Thickness
Minimum 8 inches for dock areas and approach aprons, with thickened edges at dock faces to resist impact damage from trailers and equipment.
Concrete Strength
5,000+ PSI air-entrained concrete with low water-to-cement ratio for maximum strength, durability, and freeze-thaw resistance in exposed dock environments.
Reinforcement
#5 Grade 60 rebar on 12-inch centers both ways, chaired in the lower third of the slab, with additional reinforcement at dock edges, equipment pads, and high-traffic transition zones.
Approach Aprons
Reinforced concrete approach aprons sloped for drainage, extending 50+ feet from the dock face to handle truck turning movements and trailer spotting.
Drainage Design
Engineered slope and trench drain systems that move water away from the dock face and prevent ponding in the approach area where trucks idle.
Edge Protection
Steel angle iron or heavy-duty concrete curbs at dock faces to protect slab edges from trailer impact and prevent corner spalling.
Repair vs. Replace
Knowing when to repair and when to replace saves you money and downtime.
When to Repair
- Surface spalling or scaling without structural damage
- Isolated cracks that haven't undermined the sub-base
- Joint deterioration that can be routed and resealed
- Minor settling that can be corrected with slab jacking
- Edge damage limited to the dock face area
Typical Cost: $3,000 - $8,000
Depending on repair scope and dock size
When to Replace
- Widespread cracking with sub-base erosion underneath
- Slab has settled or heaved more than 1 inch
- Original concrete was under-designed (too thin, low PSI)
- Multiple previous patch repairs that keep failing
- Drainage problems requiring re-grading the entire area
Typical Cost: $10,000 - $30,000+
Full tear-out and replacement with proper engineering
The RCC Difference
Our Build Standard
Dock concrete takes the worst abuse on any commercial site. Our dock standard is the heaviest spec we pour.
5,000+ PSI Air-Entrained, Low W/C Ratio
Dock slabs and aprons get 5,000+ PSI air-entrained concrete with a low water-to-cement ratio — the strength for impact and wheel loads, and the air entrainment for the salt, slush, and 25–30 freeze-thaw cycles a year that hit an exposed dock harder than any other surface.
#5 Grade 60 Rebar Both Ways
We run #5 Grade 60 rebar on 12-inch centers both directions, chaired in the lower third of the slab, with added steel at dock faces and transition zones. Trailer impact and forklift point loads will find wire mesh's weakness immediately — mesh that was pulled up mid-pour offers no reliable tensile capacity.
Rebuilt, Compacted Sub-Base
Most dock failures we repair trace back to sub-base erosion or clay movement. We excavate to engineered depth, treat heavy clay sub-grades, correct drainage that undermines the base, and compact 4–6+ inches of CA-6 crushed limestone before the pour.
