ENGINEERED 
RETAINING
WALLS®

​Boulder and natural stone retaining walls are one of the most popular wall types across the Western North Carolina, North Georgia, and East Tennessee mountains — and one of the most commonly built incorrectly. A boulder wall is not just a row of stacked rocks; on slopes over 4 feet, it requires engineered base prep, proper batter, drainage behind the face, and graded backfill to prevent rotation and slope failure. Engineered Retaining Walls® designs and builds boulder, fieldstone, and quarried-stone retaining walls throughout Asheville, Hendersonville, Murphy, Blairsville, Hiawassee, Blue Ridge, Knoxville, and the Tri-State mountain region. Below are the questions homeowners and builders ask us most often about boulder and stone walls.
