Unilock Concord Wall XL

Description

The built in setback design of Concord Wall automatically forms the correct slope for retaining walls, making it a trusted favorite of designers for decades. Tapered units in a 6” (15cm) height can be used to build highly stable retaining walls in straight or curved applications, and are a popular choice for accompanying steps. For faster construction and a more linear look, XL units are also available, double the length of the standard unit. Build gravity walls up to 2.5ft (1m) or grid reinforced walls up to 25ft (7.5m) high under typical conditions. Wedge cap units and 24” (60cm) coping/step tread units are also available.
