Brynion Excavation handles both concrete flatwork and asphalt paving for residential and commercial properties across Kelso, WA and the surrounding Southwest Washington region. On the concrete side, we install driveways, garage pads, shop floors, sidewalks, and patio slabs — surfaces that demand precise grading and a compacted base to stay level for decades. On the asphalt side, we pave private parking lots, commercial access roads, and rural driveways in Longview and Woodland where a flexible, fast-setting surface makes more sense than concrete. Both materials have their place, and our team helps you choose the right one for your project’s traffic, soil, and budget.

Every flatwork and paving project starts with proper site prep. For concrete, we excavate to the right depth, set compacted gravel base, and form the pour area with attention to slope and drainage so water sheds away from structures. Concrete mixes are selected for Washington’s wet winters — higher PSI where freeze-thaw cycling is a concern. For asphalt, we grade and compact the subgrade, lay a crushed-rock base course, then apply and roll hot-mix asphalt to a uniform thickness. Joints, edges, and transitions between surfaces are finished carefully to prevent early cracking. Both processes rely on grading work in Kelso, WA done right the first time.

Answers to common questions about our excavation and site preparation services in Kelso, WA.
Asphalt is generally the better choice when budget is tight, when you need the surface usable quickly, or when the driveway spans a long rural run where flexibility under load matters. Concrete costs more upfront but lasts longer with less maintenance and handles heavy vehicles well on shorter pads. In Napavine, WA‘s wet climate, both perform well when the base is properly compacted and graded for drainage — that base work is where most failures originate, not the surface material itself.
Yes. We regularly take on commercial parking lot paving projects throughout the Kelso and Longview area, including lots for warehouses, storage facilities, and small businesses. Commercial work requires thicker asphalt sections, more precise drainage planning, and sometimes engineered plans depending on lot size. We assess the subgrade, design the base depth for the expected load, and can mark stalls and install curbing or concrete aprons as needed.
Freshly poured concrete typically needs 7 days before light vehicle traffic and 28 days to reach full design strength — foot traffic is safe after 24–48 hours in normal Kelso weather conditions. Asphalt can handle light vehicle traffic within 24–48 hours of rolling, though it continues to harden over several weeks. We advise against parking heavy trucks or equipment on new asphalt during hot summer days until it has fully cured.
We handle everything in-house — site clearing, excavation, subgrade grading, base compaction, forming, and the concrete pour or asphalt lay. You don’t need to coordinate separate contractors. Keeping the full scope under one crew means the base is graded to our own specs before paving, which eliminates the finger-pointing between contractors that causes most long-term surface failures. One call gets you the complete job from raw ground to finished surface.
