Abstract: The invention discloses a containment module applicable as an auxiliary containment element for the execution and maintenance of cuts, fills, walls, etc., and more generally for the construction of several types of civil works; the module is essentially L-shaped having a long section and a short section substantially forming a right angle, the connection between them being reinforced by means of a bevel, and where the base of the long section is rough for increasing the friction with the soil.

Abstract: A wall molding has two grooves formed on opposite sides for receiving wall panels or interchangeable molding attachments. The body of the molding has a rear surface with grooves that engage a track attached to the wall. The molding also has a front surface with a decorative pattern formed thereon. Wall panels may be inserted into the grooves, thereby providing a smooth transition from wall panel surface to the other. In addition, an attachment may be inserted into one of the grooves and a wall panel in the other to provide an elegant transition between two wall surfaces that have different thicknesses.
