Allan Block Specifications

The following specifications will provide assistance to a broad range of professional retaining wall designers. These technical specifications will allow a wall designer to source and reference specific information for use in developing project documents.

The goal is to provide formatted specification sheets that summarize information published by Allan Block and other relevant publications, as well as provide a comprehensive document for most applications which utilize mortarless concrete block as a component of a segmental retaining wall.

The documents focus on composite structures built by combining an Allan Block facing unit with a reinforced soil mass, and appropriate drainage details. The intent of these specifications are to assist the local wall design engineer, but not limit their flexibility for any given design situation.
