Spokane's geography has many elevation changes which creates the need for retaining walls to establish flat usable space.
Retaining walls can be constructed from pre formed concrete blocks that vary in size and style. Pre-Formed blocks also come in a wide variety of solid and blended colors.
Natural or Boulder
Natural stone can also be used to construct retaining walls. Spokane is surrounded by rich quarries of basalt and granite stone. Natural stone walls can be constructed from small 12" stones to large 3' boulders.
