Retaining fill in a geotechnical structure

A method of forming a multi-compartment retainer construction for retaining fill in a geotechnical structure, comprising:

• providing a length of plastic material mesh which has vertically-spaced longitudinally-extending, orientated strands;
• and
• forming substantially vertical walls of a plurality of polygonal compartments by bending the mesh transversely and connecting respective portions of the mesh together at corners of the compartments, one portion of mesh forming at least two adjacent walls of a compartment and, at the corner where two said walls meet, the portion being connected to a second portion which also forms at least two adjacent walls of a compartment which latter walls meet at that corner.

A method of forming substantially vertical walls of a multi-compartment retainer construction for retaining fill in a geotechnical structure, comprising:

• providing at least one length of plastics material mesh which has vertically-spaced longitudinally-extending, orientated strands;
• and forming a plurality of triangular compartments by placing at least two elongate portions of the mesh in spaced, generally parallel planes, and interconnecting the elongate portions by a zig-zag shaped portion which is connected to the elongate portions alternately at the bends of the zig-zag.

A method of forming a multi-compartment retainer construction for retaining fill in a geotechnical structure, comprising:

• providing plastics material mesh which has vertically-spaced, longitudinally-extending, orientated strands;
• and
• forming substantially vertical walls of a plurality of compartments by placing at least three elongate portions of the mesh in horizontally-spaced, generally parallel planes, and connecting the elongate portions together by further, interconnecting portions of the mesh, separate portions of mesh being between different parts of elongate portions and the interconnecting portions only projecting through the respective elongate portion, if at all, sufficient to make the connection between the interconnecting portions and the elongate portions.

A retainer construction for retaining fill in a geotechnical structure, comprising at least one length of plastics material mesh which has vertically-spaced, generally horizontally-extending, orientated strands, substantial vertical walls of at least one compartment having been formed in the retainer construction by bending the mesh transversely, two portions of the mesh being connected together by loops, formed by transversely bending the strands of one portion, passing between the strands of the other portion so that the loops project out the opposite side of said other portion, and being retained by a rod means as a connecting member passing through the loops on said opposite side and preventing the loops being pulled back.
