Impermeable banks for canals, ponds and artificial basins

Impermeable membranes (polymeric or mineral clay) used to seal canals, ponds, and artificial basins in general, must be protected from both mechanical puncturing and from attack by UV rays, and if possible, the part above water needs to be covered by vegetation.

Both these needs can be satisfied by using the TENAX TENWEB honeycomb shaped structure, capable of retaining a sufficient thickness of topsoil to ensure surface stability is maintained.

The cellular structure can be filled above the water line with topsoil and, in the submerged section, with dredged gravel and/or concrete, and can be successively covered with a TENAX ECOMAT biomat and then hydro-seeded.

Puncturing of the membrane cannot be allowed and therefore the use of fixing stakes cannot be allowed.

It is therefore necessary to use a TENAX LBO reinforcing geogrid beneath the geocell panels for the dual purpose of guaranteeing the required tensile strength and allowing connection of the geocell walls by cable ties or other means. This system provides a completely stable integral structure.

The soil, confined by the honeycomb shaped structures, becomes very resistant to distributed loads and to the puncturing activity of concentrated loads.

The structure in general permits the increase in the bearing capacity of the soil layer in which it is placed, offering optimal shock resistance from moving loads and therefore efficiently safeguarding the underlying impermeable layer.
