Abstract
Abstract A retaining wall construction comprises modular facing blocks connected by fasteners to anchoring blocks positioned behind the facing blocks. The facing blocks are arranged in courses which overlap one another. The facing blocks, as well as the anchor blocks, have hollow, vertical throughbores. This enables interconnection of the back wall of the facing block with the anchor block by means of various types of fasteners. The retaining wall construction is especially useful in the construction of low height, gravity type walls.
