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.

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.
