Commercial Concrete Work Done Right
Concrete is the long-term choice for high-use commercial surfaces that need to hold up under repeated vehicle loads, heavy equipment, and seasonal weathering. D&J Contracting handles commercial concrete installation, repair, and replacement for curbs, sidewalks, wheel stops, pads, and parking lot flatwork throughout Southeast Michigan.
We pour to commercial specifications, not residential standards. That means correct thickness, appropriate mix strength, proper reinforcement, and attention to drainage and grade so your concrete does not fail prematurely under the loads your site actually sees.
Concrete Curbs and Gutters
New curb installation, curb replacement, and curb repairs for commercial parking lots and lot edges. Concrete curbs define lot boundaries, control drainage, and protect pavement edges from vehicle damage.
Sidewalks and Pedestrian Paths
ADA-compliant sidewalk installation and replacement for commercial properties. We pour to correct thickness and slope for commercial pedestrian traffic and freeze-thaw durability.
Concrete Pads and Aprons
Dumpster pads, equipment pads, loading dock aprons, and HVAC equipment pads. These high-load areas need commercial-grade concrete thickness to hold up under repeated heavy use.
Parking Lot Flatwork
Concrete parking stalls, service areas, and lot surfaces for properties where longevity is the priority over initial cost. Concrete lasts 30-50 years with minimal maintenance.
Concrete Repair and Patching
Spalled, cracked, or heaved concrete repaired with compatible materials and proper surface prep. We address the cause of the damage before patching so the repair holds.
Wheel Stops and Bollards
Concrete wheel stops and bollard bases installed to protect building entries, storefronts, equipment areas, and pedestrian paths from vehicle intrusion.
Commercial Concrete Specifications
Commercial concrete requires different thickness and strength than residential flatwork. Here are the standards we follow:
| Application | Thickness | Strength |
|---|---|---|
| Sidewalks and Pedestrian Paths | 4 inches | 3,500 psi |
| Curbs and Gutters | 6 inches | 4,000 psi |
| Parking Areas | 6-8 inches | 4,000-5,000 psi |
| Dumpster and Equipment Pads | 6-8 inches reinforced | 4,500-5,000 psi |
| Loading Dock Aprons | 8-10 inches reinforced | 5,000 psi |
When to Choose Concrete Over Asphalt
Concrete and asphalt serve different purposes on a commercial site. Concrete is the better choice in high-stress areas where loads are concentrated, heat is an issue, or long service life with minimal maintenance is the priority.
Common Concrete Problem Signs
- Deep cracking - Cracks wider than 1/4 inch or that pass through the full thickness indicate structural problems
- Spalling and delamination - Surface layer flaking off exposes aggregate and allows water infiltration
- Heaving - Frost heave or sub-base settlement creates uneven surfaces and trip hazards
- Joint failure - Crumbling or missing expansion joints allow water penetration and accelerate deterioration
- Settlement at edges - Sinking curb sections or edge failures indicate base issues that need correction
Why Macomb County Businesses Choose D&J for Concrete
Commercial-Grade Materials
We spec concrete to your actual load requirements - not a one-size number. Dumpster pads, dock aprons, and parking areas each get the right mix and thickness.
38+ Years of Experience
Our crews have installed and repaired concrete on hundreds of commercial properties across Macomb County. We know what holds up in Michigan freeze-thaw conditions.
Full Scope Coordination
Concrete work often coordinates with asphalt, striping, and ADA compliance. D&J handles all three, so you work with one crew and one point of contact.
A Word from Our Owner
"I see concrete poured too thin or without proper base prep come apart within a few winters. Commercial properties need commercial specs. We do not cut those corners because a dumpster pad or dock apron that fails costs far more to fix than it did to pour correctly the first time."

Frequently Asked Questions - Commercial Concrete Services
What factors influence the cost of commercial concrete work?
Area size, required thickness, mix strength, reinforcement requirements, removal of existing concrete, and site access all affect cost. We provide a written estimate after reviewing your project specifics.
How long does a commercial concrete project take?
Small repairs can be done in a single day. Larger flatwork or curb replacement projects typically take 2-5 days including cure time before the area is open to traffic.
When can the surface be used after concrete is poured?
Foot traffic is typically possible after 24 hours. Vehicle traffic should wait a minimum of 7 days for full cure. Heavy loads such as delivery trucks should wait at least 14 days. We provide specific guidance based on your concrete mix and conditions.
Do you handle permits for concrete work?
Permit requirements vary by project type and municipality. Sidewalk and curb work along public rights-of-way typically requires permits. We advise on requirements and coordinate with local authorities when needed.
Should I repair or replace my commercial concrete?
Surface spalling, hairline cracks, and minor damage can often be repaired cost-effectively. Widespread structural cracking, severe heaving, or slabs with failed bases generally need full replacement for a lasting result.
Can you coordinate concrete work with asphalt and striping?
Yes. D&J handles concrete, asphalt paving, and parking lot striping so you can complete curb replacement, lot resurfacing, and re-striping as a single coordinated project.
What causes commercial concrete to fail prematurely?
Common causes include inadequate thickness for the load, poor sub-base preparation, missing or improperly spaced expansion joints, and low-quality mix. Michigan freeze-thaw cycles accelerate any of these deficiencies significantly.
