A concrete driveway is one of the most durable surface investments you can make for a Tigard home — properly installed, it should last 30 or more years with minimal maintenance. Contractors in our network install new concrete driveways and replace failing asphalt or old concrete across Washington County.

Tigard sits along the Tualatin River south of Portland, anchored by the Washington Square retail corridor and Bull Mountain's slightly elevated terrain on the city's western edge, which gives parts of Tigard more natural drainage grade than the flatter valley floor found in some neighboring Washington County communities. The city's residential growth has continued steadily since the postwar decades, layering newer subdivisions onto an established suburban base. Portland Metro's heavy rainfall and clay-influenced soils apply fully here, and Tigard's position along the Tualatin River means some low-lying areas near the water table demand more careful drainage planning than the higher ground around Bull Mountain.

What Goes Into a Quality Driveway

A properly installed concrete driveway in Portland Metro starts with adequate base preparation — grading, compaction, and drainage planning. In Oregon's wet climate, drainage away from the structure is critical. A quality install is poured at minimum 4-inch thickness (5-6 for heavier vehicles), uses mix design appropriate for the climate, finishes with a broom texture for traction, and includes control joints to manage cracking patterns.

Concrete vs. Asphalt in Washington County

In Washington County, both materials work, but concrete has a longer service life (25-40 years vs 15-20 for asphalt) and does not require sealing or resurfacing on the same cycle. The higher initial cost is typically offset by lower maintenance over the life of the surface. Honest comparisons help you make the right choice for your situation — including the cases where concrete is not the right answer:

  • Asphalt makes sense when the up-front number is the binding constraint, when the driveway is long enough that the cost difference becomes large, or when you need the surface usable within a day or two rather than after a cure period. It needs sealing on a cycle and it will not last as long, but that is a legitimate trade rather than a mistake.
  • Gravel is the honest answer more often than contractors like to say, particularly on long rural drives where paving any surface is out of proportion to how the property is used. It is the lowest first cost and the highest recurring attention.
  • Pavers cost more than poured concrete and settle over time, but individual units can be lifted and reset — which in a wet, mossy climate is a real repairability advantage over a monolithic slab that has to be cut out to fix.
  • Concrete earns its premium when the surface carries real load, when you want 30-plus years without a maintenance cycle, or when appearance and a clean monolithic finish matter. It is also the least forgiving of a bad base, which is why the invisible half of the job decides how long it lasts.
