The TECCO® slope stabilisation system (boulder netting, flexible facing) stabilises steep, weathered slopes in place of concrete and shotcrete constructions and conventional net systems: After cleaning, leveling and profiling the surface, the TECCO® steel wire mesh can be pretensioned on the slope at a defined force using soil or rock nails and spike plates. The mesh adapts to the topography and so prevents not only slides and deformations, but also breakouts. Components
The TECCO® system consists of four main components that are carefully coordinated with each other:
TECCO® steel wire mesh
TECCO® mesh is made of high-tensile steel wire with an ultimate tensile strength of over 1770 N/mm2.
TECCO® spike plates
Rigid spike plates that are reinforced with ribbing ensure optimal load transmission from soil or rock anchors to the TECCO® mesh.
TECCO® connection clips
The connection clips high-strength steel wire connection clips enable mesh sections to be joined without overlapping and still
guarantee one hundred percent transfer of forces.
Soil or rock nails
Adapted to the local soil and rock static requirements, the TECCO® mesh can be anchored in accordance with our dimensioning concept with commercial soil or rock nails.
Dimensioning
With our RUVOLUM® dimensioning concept, the optimal forces at the anchor points can be determined as a function of the geotechnical parameters, to provide the static verification for the overall system. The relevant software is available on request.
Tests
The supporting behavior of the overall systems has been verified and confirmed by numerous tests through independent
testing institutions.
Installation
TECCO® is rapidly and simply installed in rolls of 3.5 x 30 m. The non-overlapping linking of the mesh panels
using our connecting clip essentially reduces the installation time.
Benefits
compared with supporting walls, shotcrete, wire rope nets, heavy square mesh nets and reinforced hexagonal meshes:
- system dimensioning is measurable
- freely selectable anchor points
- fast installation over large areas
- practically invisible when the vegetation establishes
- CO2 footprint is significantly better than with shotcrete
