Precast Retaining Walls are vibrated concrete structures for retaining soil. They are made up of a line of full-height modular panels. The side facing the soil is endowed with one or more vertical stiffening ribs that go from the base to the top of the wall.
They can be placed on a Precast Foundation of varying size that has been laidbeforehand. The two elements are then anchored through a concrete pour.
The Precast Foundation can be both direct (shallow) and indirect (deep). If the terrain requires it, piles or micropiles can be driven into the ground before the laying of the Precast Foundation.
The Precast Retaining Walls are produced in four different types: exposed cement facing, covered in local stone or with horizontal flowerbeds (stone-grass or cement-grass). They can be used for the construction of retaining walls for embankments, toe walls, counterscarp walls, bridge abutments, abutments for artificial tunnels and sound-absorbing barriers.
Both the precast elements and their highly automatized production techniques are protected by industrial patents and are perfectly suitable for any kind ofsoil 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.
