Our Easy Blocks retaining wall system allows for great flexibility in design and ease of installation. We also provide the engineered design for your retaining wall needs.

Make sure that you hire an experienced contractor for the installation.The base blocks can be made with sloped tops and flat bottoms to achieve a smooth battered wall finish with the desired angle. The contractor only needs to prepare a flat level base and place the base blocks on it followed by regular blocks.
