How to Install It
Dig a level trench, compact a stone base and bury the first course. Stack each course with the rear lip hooked behind the block below, stagger the joints and fill the cores and the backfill zone with clean drainage stone as you go. Keep curves to at least a 4 ft outside or 6 ft inside radius. Above 48 in, or under a driveway, pool or slope, have the wall engineered with geogrid. Glue the caps on with concrete adhesive.

How to Install It
Excavate a level trench, place and compact an aggregate base, and bury the first course as the toe. Level the base course in both directions before going up, since the lip carries the alignment of every course above. Stack with the lip engaged behind the course below, break joints, and backfill cores and the zone behind the wall with clean drainage stone as each course goes in. Hold curves to a 48 in minimum outside radius measured from the top course to the front of units, and 72 in inside. Turn returns with the universal corner. Limit gravity walls to 48 in including the buried course; surcharge from driveways, pools or slopes above the wall, and any height beyond that, need an engineered geogrid design. Adhere the 4 in cap with concrete adhesive.
