Components
The TECCO system consists of four main components that are carefully coordinated with each other:
1). TECCO steel wire mesh
TECCO mesh is made of high-tensile steel wire with an ultimate tensile strength of 1770 N/mm2.
2). TECCO spike plates
Rigid spike plates that are reinforced with ribbing ensure optimal load transmission from soil or rock anchors
to the TECCO mesh.
These plates are placed over the anchor heads and tightened to pre-tension the mesh onto the slope.The plates
are galvanized and have dimensions of 13.0''*7.5"*0.4"(330mm*190mm*10mm).
3). 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.
These claw are hot dip galvanized and consist of 0.25"(6mm) thick steel spiral.
4). 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.
The main anchors of the system are installed in a grid typically from 6.6 to 13.1 ft (2.0 to 4.0m)horizontal and
vertical spacing.Actual spacing depends upon the results of site analysis and modeling.Anchor consist of
commercially available steel bars ranging from 1.0 to 1.25 ft (25 to 32mm).
Selfdrilling grout injection anchors are also permitted.Additional anchors may also be used to provide added
support at boundaries and in low points and hollows.
