EXPOSED AGGREGATE CONCRETE IN OREGON

Exposed Aggregate Concrete Contractors in Oregon

Exposed aggregate concrete is one of the most popular surface finishes in the Pacific Northwest, and for good reason. The natural stone texture complements Oregon's landscape aesthetic, provides excellent slip resistance in wet conditions, and offers a distinctive appearance that standard broom-finish concrete cannot match. Oregon's exposed aggregate contractors use locally sourced aggregates — including Pacific Northwest river rock, basalt, and decorative stone — to create surfaces that feel native to the Oregon landscape. This directory connects you with licensed exposed aggregate concrete contractors serving all major Oregon cities.

What is Exposed Aggregate Concrete?

Exposed aggregate concrete is created by placing standard concrete and then removing the top layer of cement paste before it fully hardens, revealing the decorative aggregate (stone, gravel, or pebbles) embedded in the mix. The result is a textured, natural-looking surface where the aggregate becomes the visual and tactile feature of the finished surface. Oregon contractors use several methods to expose the aggregate: surface retarder (applied to the surface before finishing, then washed off after initial set), seeding (broadcasting decorative aggregate onto the surface), and sandblasting or grinding (for existing concrete). The choice of aggregate — size, color, and type — dramatically affects the final appearance.

Exposed Aggregate Aggregate Options in Oregon

Oregon exposed aggregate contractors offer a wide range of aggregate options. River rock from Oregon's rivers — smooth, rounded stones in earth tones — is the classic Pacific Northwest choice and is widely available from Oregon quarries. Basalt aggregate, sourced from Oregon's volcanic geology, provides a dark, dramatic appearance popular in contemporary designs. Pea gravel (small, uniform rounded stones) creates a fine-textured surface popular for pool decks and walkways. Quartz and granite aggregates are available in a range of colors for more decorative applications. Recycled glass aggregate is an eco-friendly option gaining popularity in Portland and other Oregon cities. Your contractor can show you aggregate samples to help you choose the right look for your project.

Exposed Aggregate vs. Other Concrete Finishes in Oregon

Oregon homeowners choosing a concrete surface finish often compare exposed aggregate to broom finish, stamped concrete, and stained concrete. Exposed aggregate offers superior slip resistance compared to smooth finishes — particularly important in Oregon's wet climate. It is more durable than stamped concrete because the surface texture is integral to the concrete rather than applied on top. Exposed aggregate is generally less expensive than stamped concrete but more expensive than broom finish. Unlike stained concrete, exposed aggregate's appearance comes from the aggregate itself and does not fade or peel. It is an excellent choice for Oregon driveways, patios, pool decks, and walkways where durability and natural aesthetics are priorities.

Maintaining Exposed Aggregate Concrete in Oregon

Exposed aggregate concrete in Oregon requires periodic sealing to protect the surface and enhance the aggregate's natural color. A penetrating silane-siloxane sealer should be applied every 3–5 years to protect against moisture infiltration and staining. A topical acrylic sealer can be used to enhance the aggregate's color and add sheen, but requires more frequent reapplication (every 2–3 years). Avoid using deicing salts on exposed aggregate surfaces — they can damage the cement matrix and cause aggregate to loosen. Clean the surface annually with a pressure washer and mild detergent. With proper maintenance, exposed aggregate concrete in Oregon can look excellent for 30–40 years.
