Every commercial project begins with a site walk and a written scope covering square footage, traffic type, existing conditions, drainage paths, ADA stalls, striping and phasing, so your tenants and customers keep access while we work.
Commercial Paving Specifications: Built for Truck Traffic and Spokane Winters
Light-duty passenger stalls commonly receive 2.5 to 3 inches of compacted hot-mix asphalt over a compacted base. Drive aisles, fire lanes, dumpster pads and truck routes are designed heavier, often 3 to 4 inches placed in two lifts over a thicker crushed rock section. Thickness is chosen from subgrade strength, anticipated axle loads and how much frost movement the soil can produce. Building heavier where traffic demands it, and right-sizing where it does not, keeps budgets honest without sacrificing pavement longevity.
Commercial Paving Base Design: Subbase Base Compaction That Resists Frost
Failures that appear in the asphalt almost always start below it. We strip unsuitable topsoil and organic material, proof-roll the exposed subgrade to find soft spots, and replace weak pockets with structural fill. Crushed rock base is then placed in lifts and compacted to a uniform, unyielding platform. A properly compacted subbase distributes wheel loads, sheds water and limits the differential heave that freeze-thaw cycles create.
Commercial Paving Mix Selection: Hot-Mix Asphalt Aggregate and Binder Grade
Hot-mix asphalt is a precise blend of graded aggregate and a performance-graded binder. For Spokane we favor mixes and binders suited to a climate with sub-zero winter lows and hot summer afternoons, balancing rut resistance against low-temperature cracking. Mix is delivered hot, placed with a self-propelled paver and compacted before it cools, so the finished surface reaches the density that keeps water out.
Commercial Paving Drainage: Grading & Drainage That Keeps Water Out of the Base
Standing water is the fastest route to premature failure. We verify slopes before paving, protect catch basins and inlets, and shape the surface so runoff leaves the lot instead of soaking the base. Where a property has chronic ponding, we correct the grade rather than simply paving over the problem.
Commercial Paving for Property Managers: Phasing, ADA Compliance and Striping
Occupied properties cannot simply shut down. We sequence work in sections, maintain access to entrances and accessible routes, and give tenants clear notice of which areas are closed and when they reopen. Accessible parking stalls, access aisles and curb ramps are laid out to current ADA slope limits, and new stall striping, arrows, crosswalks, fire-lane markings and wheel stops can be included in the same scope.
If your lot is structurally sound but worn, we will say so. Many commercial properties are better served by asphalt resurfacing or targeted asphalt repair than by full reconstruction, and we will price the options side by side so you can decide with real numbers.
Planning tip: Commercial paving season in Spokane runs roughly spring through early fall, when air and ground temperatures allow proper compaction. Booking late winter or early spring secures your preferred window.
Commercial Paving Process: From Site Walk to Final Stripe
- Site walk and written scopeWe measure the property, review traffic and drainage, and document existing distress so the estimate matches the real conditions.
- Demolition and subgrade preparationFailed pavement is milled or removed, subgrade is proof-rolled, and soft or contaminated soils are corrected.
- Crushed rock base installationCrushed rock is placed in lifts and compacted with vibratory rollers to a uniform, stable framework.
- Grading and drainage verificationElevations are checked against the plan so water flows to inlets and away from buildings.
- Hot-mix asphalt placementA self-propelled paver lays the mix at consistent thickness with tight joints and a smooth mat.
- Compaction and density controlSteel-drum and pneumatic rollers compact the mat while it is still workable to reach target density.
- Striping, signage and cleanupStalls, ADA markings and arrows are laid out, the site is swept, and your team gets a walkthrough.

Commercial Paving FAQ: Answers From a Spokane Paving Contractor
Commercial Paving Cost: What Drives the Price of a Spokane Parking Area?
Price is driven by square footage, required thickness, base condition, drainage corrections, access, and whether existing pavement is overlaid or removed. A written estimate after a site walk is the only reliable way to price a commercial lot.
Commercial Paving Timeline: How Long Is a Lot Closed?
Most lots reopen to vehicle traffic the day after paving, depending on weather and mix temperature. Phasing lets us keep part of the property open throughout the project.
Commercial Paving Warranty: What Protects a New Lot From Winter Damage?
The strongest protection is what you cannot see: base compaction, drainage and mat density. We also recommend crack sealing and sealcoating on a maintenance schedule to extend service life.
