Boulder and block walls are one of the most practical masonry solutions for Northwest Oregon properties. Sloped lots, clay-heavy soils, and heavy seasonal rainfall put real pressure on hillsides year-round. Without a properly built wall, that pressure leads to soil movement, erosion, and lost yard space. Holladay and Sons LLC installs both boulder walls and concrete block walls to match the structural needs and look of your property. Boulder walls use large natural stone set into a slope for a rugged, low-maintenance result that fits the Pacific Northwest landscape. Block walls use interlocking concrete units that flex with seasonal soil movement and pair well with drainage systems behind the wall. Both wall types require a solid base, proper drainage, and correct material selection for the site. We assess slope, soil conditions, and drainage before any work begins. Whether you need to stop erosion, create flat usable yard space, or define a garden terrace, we build walls that hold. Call Holladay and Sons LLC to get a site assessment scheduled.
