Seattle WA Commercial Concrete Company
We are experienced and equipped to handle an array of concrete flatwork project including sidewalk installation and repairs, curb and gutter, patios, driveways, and ADA compliant ramps. We can provide a variety of finishes including broom finish, exposed aggregate, stamped, colored, and decorative. Our crews are experienced with new construction, repairs or restoration, and projects that involve both.
Our concrete General Manager has over 15 years of industry experience and our crews have an abundance of experience not only in the industry, but working together as well.
We use a number of well-respected concrete suppliers around the Seattle area, including: Cemex, Miles Resources, CalPortland, Stoneway, and Cadman.
What’s the difference between asphalt and concrete?
Asphalt is a pavement structure consisting of aggregates, fines and a binder of liquid asphalt. The material is applied hot and is cured once it cools. Concrete is a pavement structure consisting of cement, aggregates, water and chemical admixtures. The material is applied cold and is cured once the water evaporates out. Generally, concrete is more expensive to install, but it also will have a longer lifespan.
Can it be too hot or too cold to place concrete?
Temperature extremes make it difficult to properly cure concrete. On 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 does it mean to “cure” concrete?
Curing is one of the most important steps in concrete construction, because proper curing greatly increases concrete strength and durability. Concrete hardens as a result of hydration: the chemical reaction between cement and water. However, hydration occurs only if water is available and if the concrete’s temperature stays within a suitable range.
How long does it take for concrete to cure?
Generally, concrete is cured enough for walkability within one day and for driveability within 3 days. Depending on thickness, concrete can take weeks, months or years to be fully “cured” from a technical perspective.

What are the various “finishes” that can be applied to concrete?
Broom finish, smooth (trowel) finish, exposed aggregate finish, stamped finish, etched finish.
How thick should concrete be?
For residential or sidewalk applications, concrete pours should be a minimum of 4 inches. For commercial or weight-bearing applications, it should be a minimum of 6 inches.
What makes for an appropriate sub-base?
For most medium- or light-duty commercial 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 should be.
How much does it cost?
The factors that affect the cost of a concrete job are: (1) preparation time and removal of existing concrete, (2) total job size (larger job, smaller unit prices), (3) concrete thickness, (4) detail work required and (5) the finish type. The costs of various finishes are in increasing order: Broom finish, smooth (trowel), exposed aggregate, stamped, and etched.
What factors contribute to concrete decay?
The most common factors contributing to concrete decay are sub-base or sub-grade erosion, roots, vehicle traffic (in particular heavy or high-volume traffic) and moisture penetration.
What are the different types of concrete mix?
These are the most common type of concrete mix we use in our jobs: extruded curb, exposed aggregate, ¾ minus and 7/8 minus. Mixtures with a larger number have a larger aggregate and consequently a larger weight-bearing capacity.
Who makes your concrete?
Our primary material suppliers are Cemex, Cadman, Miles Sand & Gravel and Stoneway.
Commercial Concrete Contractors
We have the experience and equipment to handle an array of commercial concrete flatwork project including sidewalk installation and repairs, curb and gutter, extruded curb, drive approaches, and ADA compliant ramps.
A well-constructed 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 most medium- or light-duty commercial applications, a 2″ 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 should be and/or total thickness of the sub-base.
Likewise, the depth of the concrete pour itself should be congruous with the needs of the end-product. For residential or foot-traffic sidewalk applications, concrete pours should be a minimum of 4 inches. For driveway approaches or commercial applications with moderate vehicle traffic, a minimum of 6 inches is required. For high volume or heavy traffic (such as semi trucks), a minimum of 8″ should be considered and also reinforcement using rebar or meshing material.
The factors that affect the cost of a concrete job are: (1) preparation time and removal of existing concrete, (2) total job size (larger job, lower unit prices), (3) concrete thickness, (4) detail work required, and (5) the finish type.
