Allison Concrete Construction

Allison Concrete Construction is a concrete contractor based in Tigard, Oregon, working across the Portland metropolitan area, inland to Bend, and along the Oregon coast between Newport and Astoria. Established in 2007, the company handles both residential and commercial concrete and holds Oregon Construction Contractors Board registration CCB# 179886.

Flatwork forms a large share of the business: driveways, patios, walkways, porches and pool decking, with coping work where a pool surround requires it. Finish options are a particular focus, and the company works in stamped concrete, exposed aggregate, broom finish, sand finish, trowel finish, coloured concrete and concrete staining. Because the finish is chosen at the point of design rather than treated as an afterthought, the company offers a design consultation at the property before work is quoted.

Structural concrete is the second side of the business. The company pours foundations and footings, builds retaining walls, and applies shotcrete — a sprayed concrete method used on slopes, walls and irregular forms where conventional formwork is impractical. Drainage installation is carried out alongside this work, which addresses the water management that governs how long a slab or wall lasts in the Pacific Northwest climate.

Site preparation and demolition are handled as well, including the removal of existing concrete and asphalt, so a replacement project does not require a separate contractor to clear the old surface first.

Commercial work covers the concrete elements of business premises and their approaches, while residential work runs from single patios through to full hardscape schemes. Service coverage includes Beaverton, Hillsboro, Gresham, Milwaukie, Lake Oswego, Oregon City, Tualatin, West Linn, Troutdale, Fairview and Wood Village in the Portland metro; Vancouver, Camas, Washougal and Battle Ground across the Washington state line; Bend in central Oregon; and the coastal communities of Astoria, Seaside, Cannon Beach, Tillamook, Lincoln City and Newport. The company covers Multnomah, Clackamas and Washington counties, and consultations are carried out on site at no charge.
