Due to the mountainous terrain of our beloved East Tennessee, a retaining wall is a must-have on many of our project sites. In fact we have built as many as seven terraced retaining walls on one property! Retaining walls are an easy place to get in big trouble down the road. If not installed properly, the can fail over time, causing all the other beauty on your property to be destroyed. As an NCMA certified retaining wall contractor, Appalachian Valley Landscape is dedicated to quality and craftsmanship in our retaining walls.
