The sack includes at least one area of protective cloth whose resistance characteristics differ from the main areas of cloth. The area of protective cloth is fastened to the outside of the sack structure so as to substantially cover a single main face thereof.

Abstract: A sack for realising civil engineering works, including a sack structure with two main faces defined by two respective equal main expanses of cloth that are joined over most of their periphery. The main expanses of cloth define an opening for introducing filling material into the sack structure when in use. The sack comprises at least one expanse of protective cloth whose resistance characteristics differ from the main expanses of cloth. The expanse of protective cloth is fastened to the outside of the sack structure so as to substantially cover a single main face thereof.

Abstract: A production plant for a ground covering structure (6) comprises a plant inlet zone and a plant outlet zone for a grid reinforcing member (10). The plant further comprises movement means (4) designed in operation to move the grid reinforcing member (10) along a predetermined path from the inlet zone to the outlet zone, supply means (11) for the supply of plastics material in the fluid state in the form of threads (7) to the reinforcing member (10) disposed along the predetermined path, and cooling means (2, 3) for cooling the plastics material in the form of threads (7) which are tangled on the grid reinforcing structure. The inlet zone and the outlet zone are disposed opposite one another along the predetermined path with respect to the supply means.

Abstract: A protective net is formed of individual loops (12, 12?, 12?) of plastics material threaded into each other. The plastics material can have a modulus of elasticity of between approximately 5000 and approximately 20000 MPa. Each loop (12, 12?, 12?) of the protective net (10) can be formed by a thread (11) of plastics material wrapped repeatedly over itself. The protective net (10) can be used in an aquaculture installation for the purpose of anti-breach protection for a cage for breeding aquatic organisms.

A reference element protrudes from the support face at a second predetermined distance from the front face, in order to abut, in use, against the at least one internal abutment surface of the similar overlying block and thus prevent the displacement thereof in only one of two directions which are transverse to the front face. The reference element includes a flattened engagement portion. An elongate slot is provided on the support face to receive the corresponding flattened engagement portion.
