Brynion Excavation installs modular concrete block retaining walls for residential and commercial sites throughout Kelso, WA, Longview, and the surrounding region. Concrete block walls — including standard CMU block, ultra block, and large-format interlocking systems — are among the most reliable solutions for managing significant grade changes, supporting heavy loads, and creating clean, linear landscape edges. Each block interlocks to distribute lateral soil pressure evenly across the wall face, making them particularly well-suited to steep residential yards, commercial parking lot perimeters, and industrial storage pad walls throughout southwest Washington.

The installation process matters as much as the block itself. Brynion Excavation begins every block wall project with proper base excavation and a compacted gravel footing — skipping this step is why many DIY block walls tilt or settle within a few years. We step the base course with the natural slope of your property, backfill in compacted lifts, and install perforated drain pipe with crushed rock to relieve water pressure behind the wall. For taller walls, we incorporate geogrid reinforcement at engineered intervals to extend the wall’s structural capacity without increasing block thickness.

Answers to common questions about our excavation and site preparation services in Kelso, WA.
Standard modular retaining wall block is typically used on residential projects up to four or five feet in height. Ultra block and large-format interlocking concrete blocks — some weighing over 1,000 pounds each — are used on commercial, industrial, and high-load applications where a standard block wall would require excessive width or geogrid reinforcement to achieve the same result. Brynion Excavation can recommend the right block system based on your wall height, load, and budget.
A block retaining wall installed with a proper compacted base, correct drainage, and compacted backfill can last 30 to 50 years or more. The most common cause of premature failure is inadequate drainage behind the wall, which allows hydrostatic pressure to build up and push blocks out of alignment. Brynion Excavation builds drainage into every block wall project as standard practice.
Yes. Brynion Excavation steps the base course of every block wall to follow the natural slope of your site. This keeps the first course level and the wall structurally sound, regardless of how much the surrounding grade changes. Stepped base courses are standard practice for sloped Kelso and Longview properties, where flat building areas are often created using a combination of excavation and block wall terracing.
Geogrid reinforcement is required for taller block walls — typically those exceeding three to four feet, depending on the block system and soil conditions. Geogrid is a synthetic mesh layer buried in the backfill at engineered intervals; it ties the soil mass behind the wall to the block face, dramatically increasing the wall’s resistance to overturning. Brynion Excavation follows manufacturer specifications and local code requirements to determine when and how geogrid is incorporated.
