Retaining blocks

Retaining blocks:

Retaining blocks as a method of construction has many advantages. Construction speed and immediate utilization contribute to low labour cost.

The retaining blocks are placed on a gravel or concrete foundation which makes the construction flexible to accommodate ground movement.

Successive courses are stacked after compaction of the sand filled in behind the blocks. Internal soil pressure and overturning is resisted by the shear forces between courses, mechanical interlocking and weight of units (28 kg) and weight of infill behind blocks.

A professional engineer should be consulted if there is uncertainty about soft or loose soil, ground water or excessive height.
