Abstract: A brick or construction element comprised of cement or synthetic sand and/or gravel of the kind for erecting high embankments or earthworks has a shield-type support with a flat front wall to which are connected lateral wing sections angled toward the rear. A tie bar extends rearwardly from the center of the shield-type support and bottom walls are located between the shield-type support and the tie bar. Boreholes are provided through the wing sections and through the free end of the tie bar, into which reinforcing bars are inserted to enable the bricks to be held together when stacking them in courses to form a retaining wall.

Abstract: An edging element for playing fields and sports installations has an elongate elastic profile top and a strip for anchoring the edging element inside of the profile top in a concrete slab in interlacing relationship with a straight reinforcement rod. That anchoring strip extends along and projects from the elongate profile top and has a series of apertures distributed along at least one line parallel to the elongate profile top for receiving the reinforcement rod alternatively from different sides of the anchoring strip which is of sufficiently elastic material to form an interlacement with the straight reinforcement rod. The anchoring strip is made flat prior to its enlacement with the straight reinforcement rod but is interlaced with that straight reinforcement rod to have sections between successive apertures located alternatively at opposite sides of said straight reinforcement rod.
