A modular block wall includes dry cast, unreinforced modular wall blocks with anchor type, or frictional type or composite type soil stabilizing elements recessed therein and attached thereto by vertical rods which also connect the blocks together. The soil stabilizing elements are positioned in counterbores or slots in the blocks and project into the compacted soil behind the courses of modular wall blocks. Alternative stabilizing element designs may be used with the modular wall blocks and other types of facing elements in a mechanically stabilized earth structure.

A block assembly includes integral connection mechanisms specifically designed for incorporation into engineered retaining walls. These connection mechanisms specifically accommodate the use of reinforcing grids in the formation of a retaining wall which, when used, will stabilize the retaining wall and provide additional strength. The connection mechanism is formed prior to fabrication of the block itself, and thus can be integrally incorporated during casting/fabrication of the block itself. The connection mechanism defines a connection slot usable during retaining wall fabrication (by allowing easy connection to the reinforcing grid) while also accommodating holding and lifting of the block assembly. Due to the fabrication method, the configuration of the connection mechanisms inserted into the block can be uniquely designed to provide desired physical coupling once the concrete is hardened. This further allows the use of different materials and different structures to provide the desired strength and allow the use of optimal materials.

An earthen work bulk form construction has a wire mesh facing and granular compactable fill with stabilizing members projecting horizontally into the fill from the front facing. The front facing is comprised of modular shaped panels which form a mosaic pattern that enables construction of the wall with non-adjacent panels serving to facilitate and support adjacent panels. Connection of the stabilizing members to the front panels is effected through a quick engagement and locking handle bar connector. A handle bar connector is used for connecting a cast in place front wall to the front panels and bulk form.
