SPIDER®-System: Active protection for blocky rock slopes

The SPIDER® spiral rope net made from high-tensile wire secures loose, blocky rocks, rock spurs, overhangs or unstable rock formations with highly irregular surface structures. The SPIDER®-system utilizes a flexible nail grid and boundary ropes together with the spiral rope net.

High-tensile steel wire

One single wire has a tensile strength of more than 1770 N/mm2 limiting elongation and keeping the mesh highly pre-tensioned, providing reliable stability for the slope and minimizing deformations.

Harmonized system

Each system element is designed to work in perfect harmony with the rest, ensuring that the forces are transferred efficiently over the entire system. The dimensioning is carried out with our free dimensioning software RUVOLUM®.

Rhomboid mesh wire structure

Our unique mesh shape transfers forces to the nails very efficiently, preventing deformation within the system. The mesh provides the best possible stability for the geological conditions on site and can be tightly secured even on irregular terrain.

Knotted ends

These ensure that maximum stability is retained right up to the border edges, removing the need for overlap and allowing the mesh and netting to be unrolled easily and independently.

Lightweight

The high-tensile steel wire's outstanding strength-to-weight ratio makes transport and installation easier. Unstable slopes are given long-term stability with minimal visual impact.

Corrosion protection

With GEOBRUGG SUPERCOATING® or GEOBRUGG ULTRACOATING® our systems are designed to last for generations and require very little maintenance. For particulary demanding environments we offer our products in stainless steel.
