Precast Retaining walls are concrete structures for retaining soil. They are made up of sequence of full-height modular panels (width 1.25 m or 2.50 m). The side facing the soil is endowed with one or more vertical stiffening counterforts wich extend from the base to the top of the wall.
They are placed on a underpinning slab which has been cast-in-place beforehand and whose depth is between 15-20 cm. It is then anchored through the casting of the foundation (shallow or deep, with the construction of piles or micro-piles, if the terrain requires them).
The Precast Retaining Walls are produced in four different types: with fair-faced concrete, covered with local stone, stone-grass or concrete-grass. The precast elements can be used for the construction of retaining walls for embankments, counterscarp walls, bridge abutments, abutments for artificial tunnels and noise barriers.
Both the precast elements and their highly automatized production techniques are protected by industrial patents and are perfectly suitable for any kind of soil pressure, be it low, medium or high. The wall facing can be made perpendicular to the laid substructure or inclined between 0% - 15%. Placement is very quick and produces a structure which is ready to be filled.
