WARNING

This information applies to Lock-Block(tm) products only. Other blocks do not meet our strict dimensional tolerances and do not lock together into a cohesive wall as well as Lock-Block(tm) units. Using copy-cat blocks with Lock-Block(tm) engineering data could result in wall failures.

Gravity Walls:

Gravity walls use additional blocks behind the face of the wall to reinforce wall strength and stability. No tiebacks are needed. Gravity wall are best in a "cut" situation. Download Instructions Here
