Retaining walls

A retaining wall is built to support vertical slopes of earth and rock etc. The retained soil, or backfill, when waterlogged can increase in weight by many times the original dry weight. There are many types of retaining wall structure, some built with large 1 ton plus blocks, and typically in Spain Escoyera, which is a wall of very large boulders backfilled with smaller rock and soil. More often in smaller areas, or areas with limited access we use steel reinforced walls that are filled with concrete that is "blown on" under pressure. This is commonly known in Spain as Gunite.

The video below is a retaining wall being created in Moraira. You will see the whole process from digging the trenches to building the steel, Guniting and cladding with stone to decorate.
