Concrete Patio Installation in Portland, OR

Portland averages about 37 inches of precipitation a year at the airport station under NOAA's 1991-2020 climate normals, with downtown running higher — concrete drainage design is essential here. The wet climate also causes more frost heave and base erosion under slabs than in drier regions, making proper base preparation critical to long-lasting pours.

A concrete patio extends your Portland home's usable living space and holds up to Oregon's weather better than wood decking or pavers. Contractors in our network install plain, broom-finished, stamped, and exposed aggregate patios across Multnomah County.

Patio Options for Portland Metro Homes

Plain broom-finish concrete is the most cost-effective and durable — slip-resistant, low-maintenance, and long-lasting. Stamped concrete adds visual interest with patterns that mimic stone, brick, or tile at a lower cost than the real material. Exposed aggregate has a natural texture that provides excellent traction and works well in Oregon's rain. Options are discussed based on your budget and use case.

Drainage Planning for Oregon

Oregon's rainfall volume means every patio needs a clear drainage plan. Proper planning pitches the slab away from the structure, designs the surface profile to move water off quickly, and considers drainage channels or French drains when the surrounding grade requires them. A patio that holds water in Multnomah County's winters becomes a problem in 5 years.

Frequently Asked Questions

What is the best concrete finish for a patio in Oregon's wet climate?

Broom finish is the most reliable choice for traction in wet conditions and is the lowest-maintenance option. Exposed aggregate also performs well in the rain due to its natural texture. Stamped concrete looks great but needs more attention to sealing and can be slicker when wet, so we discuss the tradeoffs based on how the space will be used.

How do you keep water from pooling on a new patio?

We pitch every patio slab away from the house at a slope sufficient to move water off the surface, and we plan the surrounding grade or drainage channels when the site requires it. A patio that holds standing water in Multnomah County's winters will deteriorate faster and can be a nuisance to use.

Can I add a patio onto an existing slab, or does it need to be a new pour?

It depends on the condition of what is there. If an existing slab is sound, level, and properly sized, we can sometimes build onto or resurface it. If it is cracked, undersized, or poorly drained, a new pour tied in correctly is usually the better long-term investment.

How long before I can use a new concrete patio?

Foot traffic is generally fine within a couple of days, but we recommend waiting about a week before putting furniture or grills on it and closer to a month before heavy planters or hot tubs, giving the concrete time to reach full strength.

Not Sure If You Have a concrete contractor Problem?

Many homeowners aren't sure what they're seeing. We put together a straightforward guide to the warning signs that are worth taking seriously.
