Retaining walls do so much more than simply hold back the earth. Today, retaining walls have become practical as well as beautiful backyard architecture. With the variety of materials now available, retaining walls can be built in curved lines, semi-circles, convex curves, zigzags and any variety of patterns you might imagine. Choose from traditional brick and concrete to plastic, natural rocks and stone. As a bonus, nearly all retaining wall materials today are strong, durable, weather and climate resistant and require little or no maintenance to look beautiful for decades. Ask about segmental concrete blocks – a popular choice as they need no mortar and are available in a variety of shades, patterns and dimensions.
