Features & Benefits
StoneTerra
The StoneTerra Wall System requires very little labour and is extremely easy to work with. For an installer this equals greater savings. These blocks can be installed quickly with small equipment and a two-man crew. These large modular blocks can be used in gravity or geogrid configurations. There is a reduced amount of aggregate as StoneTerra blocks are solid. The shape of the block allows tight curves to be created without specialty blocks or field modifications.
Sanderson Concrete’s retaining wall systems are available in a variety of block sizes to suit any project requirement. The Full Block measures 24″ × 48″ and weighs 1,750 lb (794 kg), while the Full Bench version offers a lighter 1,375 lb (624 kg) option. For smaller applications, the Half Block (24″ × 24″, 905 lb / 410 kg) and Half Bench Block (695 lb / 315 kg) provide flexibility and easier handling. The Full Corner Block (2,300 lb / 1,043 kg) ensures structural stability at wall edges, and the 12″ Block (12″ × 48″, 875 lb / 397 kg) is ideal for finishing or low-height retaining walls. Together, these modular options allow for efficient installation and precise design versatility.
