The soil making up a slope often has a predominantly
arid matrix (due to the lack of organic material); this occurs,
for example, while cutting rocky or, in some cases, arid slopes during road construction.
Under these conditions, it’s necessary to ensure that an adequate
thickness of topsoil is provided to allow for the growth of vegetation.
Since topsoil has poor mechanical properties it can easily slide
down the slope, it could also get washed away by heavy rainfall prior to the onset of vegetative growth.
TENAX TENWEB geocells allow for the stabilisation of the topsoil even on very steep slopes,
ensuring the lateral confinement of the slope itself.
to their maximum extension and filled in with lightly compacted
topsoil, a stable planting structure is formed.
The surface of this layer can be further protected against superficial
erosion through the use of geomats or biodegradable mats.
When eroded slopes are made from soft rocks and exhibit an unstable
combination of loose rocks mixed with finer material, it’s
necessary to build a secure system capable of preventing the detachment
of the heavier and larger sized material and simultaneously retaining
any growing medium.
TENAX 3D Grids MS multi-layer geogrids are particularly useful in this situation
due to their high tensile strength and their dense mesh structure
that is capable of molding itself to the foundation profile.
provides an effective containment system for the grassed areas,
protecting the latter from erosive phenomena associated with precipitation
or with non-channelled flowing waters.
TENAX TENWEB geocell is covered with biomats or geomats and hydroseeded to prevent rainwater erosion.
