Slope crest enlargement
In many circumstances, the need to modify a slope’s geometry
can arise: to build parking lots or transit zones in the vicinity
of houses or industrial buildings; to enlarge or reconstruct hillside
roads; to construct new buildings or also, easier yet, to increase
the cultivable surface along mountain slopes by building terraces.
If such a project cannot be carried out maintaining the natural
angle of repose of the existing slope due to obstacles present
at the base (rivers, roads, adjoining properties), it may then
necessary to construct a very steep slope, which in some circumstances,
can be completely vertical.

Geogrid reinforced slope to enlarge existing area |
|
TENAX TT SAMP geogrids
allow the construction of steep slopes and walls with any type of
soil; the front face can be planted or hydro-seeded or, if needed,
it can be faced with prefabricated concrete elements.
The original slope must be cut at the base for a span wide enough
to permit the placement of the geogrids (on the average this width
is about 60%-70% of the height).
All construction operations can be performed with normal earthmoving
equipment and unspecialized labor.
Due to the small working area required, traffic and normal human
activities in the area nearby the slope will suffer minimum disturbance.
