TENAX
MULTIMAT geomats
The three-dimensional “gripping” TENAX
MULTIMAT and TENAX MULTIMAT R geomats are purposely designed for
the protection and planting of slopes subjected to surface erosion
whenever a suitable vegetative substrate soil already exists. They
have a thickness of about 20 mm and are manufactured by assembling
and stitching together several layers of polypropylene (PP), extruded
bioriented geogrids.
The process of molecular stretching, both in
the longitudinal and transversal directions, considerably enhances
the mechanical properties of the base polymer, thus providing a
high tensile strength (minimum of 8 kN/m).
Geomats of this kind
are composed of two layers of geogrid placed above and below a single
central layer, mechanically folded so to give thickness and three-dimensionality
to the geomat. The two flat geogrid layers confer a high tensile
strength and allow for minimal elongation of the geomats. The dense
folding of the central core limits the deformation of the geomat
when filling with topsoil conferring it with optimal bearing strength.
The layers are held in place by mechanically stitching them together
with a highly resistant polypropylene yarn during the manufacturing
process.
