Campbell Concrete is a locally owned and operated family business based in Corvallis, OR. We started this business in 2007 with nothing but hard work and a little prayer. Today we have grown into one of the premier concrete companies in the Willamette Valley.
Daniel and Angela Campbell are the owners of Campbell Concrete. Both were raised in the Corvallis area and continue to live here with their 3 kids. Daniel runs the day to day aspects of running the business and Angela takes care of the behind the scenes paperwork and payroll. Both are invested in the local community through kids sports, school, church, and other volunteering areas.

Frequently asked questions
What time of year can I get my project done?
We work year-round. we understand we may get wet, some of us enjoy it! We take as many precautions as we can with each project. We typically do not pour in the rain or freezing temperatures, although we have learned to work with and around the weather to get things done. Know this- the quality of your project is more important to us than schedule or risking a bad outcome.
Do we need rebar or other reinforcement?
Yes. We use rebar, or some kind of reinforcement on almost every job. We know, as concrete professinals, that concrete cracks. Once it does crack, we need to keep it from separating. We have all seen cracks in concrete that have become trip hzards- rebar helps prevent that. The only jobs that we do not use reinforcement are typically municipal sidewalks and driveway approaches- as they will not allow. (easier to tear out?)
How thick do you pour concrete?
We typically pour driveways, patios, walkways at 4'' thick. This has worked well for standard residential traffic. On some commercial work and City work thicker concrete is required for heavy vehicle traffic. If it is a wall or foundation we are pouring, the thickness is typically determined by the load that is going to be applied. We can help you determine what thickness would be requred.
Do we need an aggregate base under our concrete?
Typically you do. Here in the Willamette Valley we have some very expansive clay soils. We install a 4'' crushed rock base under all driveways and 2'' crushed rock under patios and walkways. Proper compaction of the rock base gives you a solid foundation for your slab. The rock base provides you with a buffer between the expansive (moving) clay soil and the concrete slab. The rock base also provides a drainage layer, as clays are slow to drain. When installing concrete footings below the frost line, we do not always need a rock base in those cases.
Do we need to cure the concrete?
Typically you do. We spray cure/seal on most all flatwork after the final finishing steps. The cure/ seal forms a membrane (usualy clear) that protects the concrete drying too quickly from the sun, wind, etc. Other ways to cure concrete could be water cure (ponding, sprinkler, etc.) or plastic sheeting. There are drawbacks /benefits and different applications for all types of curing. Your concrete professional should be able to explain options for your specific project.
Is sealing the concrete necessary?
With some finishes, Yes. Concrete sealer is designed to be applied after 28 days of concrete curing. Some finishes- stamped, stained, etc, need a sealer to act as the wear surface from vehicles, foot traffic, rain, etc. If the sealer layer is not kept up/ maintained, the wear surface becomes the top layer of concrete - the cement and color. this will eventually leave you with a worn surface and little to no color left. Some finishes do not require a sealer as a wear surface as much as others, but sealers also help bring out the aggregate color, give a satin sheen, protect the concrete from freeze thaw cycles, and help prevent staining.
Do we need "joints" or "cut lines" in our concrete?
Yes. Concrete cracks. Joints- whether hand cut or saw cut are meant to control the cracking. These joints are approximately a 1/4 depth of the concrete thickness. These joints give the concrete a weakened plane in which to crack. As concrete professionals, we apply our knowledge of concrete cracking rules. This allows us to layout each projects joints to minimize the chance of a stray crack. If a stray crack does happen (which is possible even with great planning and workmanship) cracks can not open up because of the rebar that is installed as well.
Why is Campbell Concrete's price higher (or lower) than other concrete companies I have bids from?
Usually it is rare to really have an "apples to apples" comparison. We all see things differently, and have unique ways to tackle each project. At Campbell Concrete, we try to give you the best value for the materials and installation workmanship. We stand behind our work, and have great pride to live and serve in the local communities. We have extensive knowledge in our chiosen field, and will work with you to get your project done in a timely matter and with professionalism.
