Masonry stone walls are retaining walls with or without concrete block foundations. Mortar adds strength and longevity, and keeps the stones in place. Masonry walls also include attention to drainage with drainage gravel, fabric, and outlets to prevent hydraulic pressure from damaging the wall.

Natural stone walls are retaining walls constructed from cut stone without the use of mortar or other adhesives to hold the wall in place. Instead, the wall is held together by friction and the weight of the stacked stones.

Natural stone is a popular alternative to the traditional modular cement block for retaining wall construction. Dry-stacked, natural stone walls add a very natural look to any landscape as the material is taken right from the ground. Natural stone walls allow water to flow freely behind and through the wall thus relieving a significant amount of pressure on the wall.
