Concrete slab installation in Tigard, done the right way
If you are planning a new patio, garage, shed, shop, or room addition in Tigard, the concrete slab is what makes everything else work. Legendary Concrete Tigard focuses on concrete slab installations that match real local conditions, like our wet winters, clay-heavy soils, and sloped lots. Instead of taking a one-size-fits-all approach, we look at what will actually sit on that slab, how the site drains, and what the city or county will require.
Most Tigard homeowners call us for slabs for garages, RV pads, backyard patios, hot tubs, small ADUs, and equipment pads. Each of these needs different thicknesses, reinforcement, and finishes. For example, a simple walk-out patio might use a 4 inch slab with wire mesh, while a garage or RV pad usually needs 5 to 6 inches with rebar on a compacted gravel base. We explain those differences in plain language before you ever sign a contract.
From the first visit we measure the slope of your yard, check where water currently flows, and look for problem soil like soft pockets or organic fill. If the ground is not solid, we correct it before concrete is ever ordered, so you are not dealing with cracks or sinking in a few years. We also talk about how you plan to use the space so we can recommend the right thickness, control joint layout, and surface texture for long term performance.
Our step by step slab process in Tigard
A solid concrete slab starts long before the truck shows up. Legendary Concrete Tigard follows a clear process that we walk you through in advance.
First is layout and excavation. We mark the slab footprint based on your plans and verify property lines where needed so you do not end up over a setback. For most residential slabs in Tigard, we remove grass and topsoil, then dig down to reach firm subgrade. If we find soft or waterlogged soil, we over-excavate and bring in compacted crushed rock, commonly 3/4 inch minus, to create a stable base and help drainage.
Next comes base prep and forms. We place and compact the gravel base in lifts, usually to 4 to 6 inches, using plate compactors so we reach the density needed to support the slab. We then set forms using straight lumber or engineered form boards, checking for square corners and the correct slope so water sheds away from your house. On patios and walks we typically pitch the slab about 1/8 to 1/4 inch per foot away from structures.
Reinforcement and concrete placement come after that. Depending on the use, we install rebar in a grid pattern or welded wire mesh and use plastic chairs or dobies so it stays in the middle of the slab, not on the bottom. When the ready mix truck arrives, we place the concrete, vibrate key areas, and screed it to the finished elevation. We cut control joints while the concrete is still workable or saw cut them soon after, to help control where shrinkage cracks appear.
Finishing and curing are the final steps. For patios and outdoor slabs we usually recommend a broom finish for slip resistance in the rainy season. For interior or garage slabs, you might choose a troweled finish that works well under floor coverings. We apply curing methods suited to the weather, such as curing compound or wet coverings, so the surface does not dry too fast and weaken. Before we leave, we review care instructions so you know when you can walk, park, or build on your new slab.
Design options for your concrete slab
A concrete slab does not have to be plain gray. Legendary Concrete Tigard can tailor the look and function of your slab so it fits your home and how you want to use the space.
For patios, hot tub pads, and outdoor living areas, we can add color directly into the concrete mix or apply stain after the slab cures. We can also add decorative cuts that create the appearance of large tiles, or combine a smooth border with a broom finished center. In many Tigard neighborhoods with established landscaping, customers like a subtle integral color like light tan or charcoal that blends with existing stone or siding.
If you are planning a workshop, garage, or ADU, we can finish the slab with a smooth trowel and then seal it or prep it for epoxy. In these spaces we also talk about practical details like thickened edges where walls will sit, conduit or plumbing that needs to come up through the slab, and anchor bolt locations. Getting these decisions made before the pour saves you from cutting or drilling into finished concrete later.
We also help you think through elevation and step transitions. Many Tigard lots have some slope, so we often design slabs that tie cleanly into existing porches or walkways without creating trip hazards. That might mean a small step, a gentle ramp, or a flush transition that works with future pavers or deck sections. During planning we can sketch simple layout options and explain the tradeoffs so you choose the one that fits your budget and long term plan.
Permits, inspections, and local considerations in Tigard
Concrete slab projects in Tigard often require more than just a contractor and a truck. Legendary Concrete Tigard helps you through the city and county steps so the job passes inspection and does not create trouble when you go to sell the home.
For structural slabs that will support a building, such as garages, additions, or ADUs, the City of Tigard or Washington County usually requires a building permit and an inspection of the forms, reinforcement, and base before concrete is poured. We can coordinate with your designer or engineer, interpret the plans, and schedule inspections so the project stays on track. For simple flatwork, such as small patios or walkways not tied to a structure, a permit is often not required, but we still follow best practices for drainage and setbacks.
We are also careful about utilities and drainage. Before excavation we call 811 for utility location, then mark out any lines that cross the proposed slab area. With Tigard’s steady winter rain, we pay close attention to how water will move after the slab is in place. Sometimes that means adjusting the slab elevation, adding a drain, or shaping surrounding soil and gravel so you do not end up with water against your foundation or pooling on the slab.
If your property is part of an HOA, we can provide simple plan sketches, color samples, and finish descriptions to help with architectural approval. We understand that each HOA in the Tigard area has its own rules about visible concrete, fencing, and setbacks, so we help you prepare what they typically want to see before you submit your request.
What affects cost and how we prevent common slab problems
Two slabs can look similar and cost very different amounts. Legendary Concrete Tigard is upfront about what affects pricing so you understand where your money is going.
Site conditions are often the biggest driver. A flat, easily accessible backyard with firm soil costs much less to prepare than a sloped area that needs extra excavation, retaining edges, or significant gravel to create a stable base. Tight access that forces us to wheelbarrow concrete instead of using a chute or pump can also add labor. We explain these factors during the estimate and show you where you can scale back and where it is risky to cut corners.
Thickness, reinforcement, and concrete mix also matter. A light use patio slab with standard mix is less expensive than a heavily reinforced slab for an RV or shop that needs higher strength concrete. We specify the mix design and reinforcement in writing so you know exactly what is being installed. If you are comparing bids, we encourage you to ask each contractor about these details so you are not choosing purely on price.
We also focus on preventing the problems we see around Tigard: cracked corners at steps, uneven settling near downspouts, and slabs that tilt toward the house. To avoid these, we design control joint layouts that fit the slab shape, compact base thoroughly near edges, and make sure water has a clear path away from structures. When conditions are challenging, such as expansive clay or areas that stay soggy, we might recommend thicker sections, additional gravel, or even a simple drain solution instead of pretending those risks do not exist.
Before any work begins, you get a clear written scope that spells out preparation, thickness, reinforcement, finish, and cleanup. During the job, we stay in touch about schedule and weather, since rain and temperature can affect pour dates. When we are finished, we review your new concrete slab with you, point out the control joints and edges, and go over realistic expectations about hairline cracking, sealing, and future maintenance so you know exactly what to expect over the life of the slab.
