A retaining wall is a structure designed to hold back soil, preventing erosion and maintaining different ground levels on either side. It restrains soil on steep slopes that would otherwise collapse, creating level areas for patios, gardens, driveways, or even basements.

Beyond utility, retaining walls add dimension to landscapes—incorporating curves, built-in planters, lighting, or seating—while blending with patios, walkways, ponds, or waterfalls for a cohesive outdoor oasis.
