Seattle Commercial Concrete Contractor Company
For new construction, repairs, and maintenance, we provide a variety of flatwork concrete services for our commercial and industrial customers. These include:
- Curb and gutter
- ADA compliant ramps
- Driveway approaches
- Reinforced concrete
- Exposed aggregate
- Broom finish
- Fiber mesh
A well-constructed commercial concrete project starts with properly assessing what the surface will be used for and designing a sub-base and concrete thickness that will be suitable for the weight-load requirements. For greater weight-bearing requirements, we can increase the sub-base thickness, aggregate size or thickness of the concrete slab.
The factors that affect the cost of a concrete job are: (1) preparation time and removal of existing concrete, if any; (2) total job size (larger job, lower unit cost); (3) concrete thickness; (4) detail work required; (5) the type of finish.
Commercial Concrete FAQs
What temperatures are required for pouring concrete?
Temperature extremes make it difficult to properly cure concrete. On very hot days, too much water is lost by evaporation from newly placed concrete. If the temperature drops too close to freezing, hydration slows to nearly a standstill. Under these conditions, concrete ceases to gain strength and other desirable properties.
What is an appropriate thickness for concrete?
Residential driveways and sidewalks are poured at a minimum of 4 inches. For commercial concrete (or weight-bearing concrete) applications, it should be a minimum of 6 inches, sometimes much more for heavy uses. Main arterial roadways or trucking warehouses are often 12 inches.
What type of sub-base is necessary for structural stability?
For most medium- or light-duty commercial concrete applications, a sub-base of 5/8 minus crushed rock properly compacted is appropriate. The greater the weight-bearing capacity required at the surface, the larger the sub-base aggregate and total thickness should be. For some heavy use projects, a sub-base of ATB (asphalt treated base) or CDF (controlled density fill) is used.
How much will a project cost?
Factors that will affect the cost of a concrete job are: (1) prep time and removal of existing concrete, (2) total job size (larger job, smaller unit prices), (3) thickness of the concrete, (4) detail work required and (5) the type of finish.
