Block-Lite manufactures a full line of Rockwood retaining walls. These units are often referred to as
Segmental Retaining Walls (SRW’s) or dry stack wall units. They can be used for large commercial
applications or modest backyard landscapes. Retaining walls give you the ability to stabilize sloping
terrain as well as define and maximize usable space. Another great advantage to these units is that they
are simple to install. They are a dry stack unit, meaning they do not require mortar joints. They are
engineered to interlock with one another eliminating the need for a skilled mason. However, for
complex wall designs or walls higher than 4 feet we highly recommend seeking professional engineering
and installation services. Most jurisdictions require a plan and building permit to construct a retaining
wall over a specified height, usually 4 feet.
