Parking lots take punishment. Trucks, freeze-thaw cycles, salt, and years of daily traffic demand a slab that's sized right, jointed right, and drained right from day one. We pour lots that stay flat, shed water, and hold up for three decades. Asphalt fails in five to seven years; concrete built to spec outlasts it by a factor of four. Every project includes a free site visit and written quote.
Asphalt looks cheaper at the start. By year three, it needs crack-sealing. By year seven, it needs an overlay. By year fifteen, it's gone. Concrete costs more to install but runs circles around asphalt over the life of the lot. A 30-year ownership cost comparison isn't even close, concrete wins decisively.
The difference is in the foundation. We compact the subgrade to spec, place base layers to the engineered depth, size the slab for the heaviest vehicle that will ever park there, cut control joints in the right pattern so cracks go where they belong, and slope the surface so water runs off instead of pooling. These details are what separate a lot that lasts from one that fails.
We measure the lot footprint, review soil conditions, identify the heaviest vehicles (delivery trucks, fire apparatus, customer cars), and calculate the required slab thickness. The drainage plan and joint layout are finalized before any equipment arrives.
Excavate and prepare subgrade
The lot is excavated to the engineered depth, soil is compacted to the specified density, gravel base layers are placed and compacted in lifts, and the surface is brought to the planned elevation and slope.
Form, reinforce, and set slope
Perimeter forms and internal joint lines are set, rebar or wire mesh is placed where required, the base is final-graded to the drainage slope, and the entire layout is verified against the engineered plan.
Pour, finish, and cure
Concrete is placed and screeded to the planned slope, finished with a broom or rake for traction, control joints are saw-cut on schedule, and the lot cures before opening to traffic.
Joints and drainage
Control Joints Direct Cracks Where They Belong
Concrete slabs will crack. The art is making sure those cracks happen in the saw-cut joints where they're invisible, not randomly across the field. Joint spacing, depth, and the timing of the saw-cut all factor into the outcome. We engineer all three based on the slab thickness, the pour conditions, and the expected loads.
Drainage is equally critical. A lot that holds water freezes that water every winter, and the surface spalls and deteriorates. We slope every lot to catch basins or drainage edges so water sheds immediately. The slope is verified against actual site conditions, not just the plan drawing. Ponded water is a non-negotiable failure point, so we design it out from the start. Coordinate with commercial sidewalk work and ADA ramp tie-ins for a complete site solution.
Slab thickness, joint spacing, asphalt comparison and what it takes to build a lot that lasts.
Concrete for long-term lots with trucks, fire access or heavy daily use; asphalt only for short-term lots where lifespan does not matter. The 30-year cost of ownership strongly favors concrete on any serious commercial lot.
Several inches over the prepared base for car-only lots; thicker for truck or fire access. The exact slab thickness comes from the engineered load analysis; we will not pour a thinner slab to save money up front because it will fail later.
Control joints saw-cut at engineered spacing force cracks into the joints where they are invisible. Joint depth, timing and pattern all matter; we engineer all three for the slab thickness and pour conditions.
Yes if it is sloped and drained correctly. Every lot we pour slopes to catch basins or drainage edges, and the slope is verified against the actual conditions, not just the plan. Ponded water freezes and spalls; planned drainage is non-negotiable.
Cars within a few days, trucks longer, full structural strength at the standard concrete cure schedule. The exact return-to-service timeline is in the quote so you can plan operations around the pour.
Client reviews
What Detroit Operations Say About Their Parking Lots
Replaced an asphalt lot that had failed in eight years with a concrete lot engineered for our delivery trucks. Three years in, zero maintenance, zero pooling, zero cracks outside the joints.

★★★★★
Drainage plan was their first conversation, not the concrete. Lot sheds water perfectly through every melt, no ice patches in customer areas. The engineering paid off.
Z. I.
Retail Center Owner, Warren
★★★★★
Engineered slab thickness for the actual truck weights, not the cheapest spec. The lot has handled five years of daily semi traffic without a single failure point.
Q. J.
Warehouse Operations, Ann Arbor
★★★★★
Pour was sequenced around our tenant schedules. Sections closed only when they had to be, opened back up on time. Real operations awareness, not just concrete crew.
