Belgo Malha Talude

DESCRIPTION / FEATURES

MT mesh constitute a system that can be set up for boulder detachment control (it forms a uniform membrane that will act to control the trajectory of eventual slipping stones. This high-strength metallic “curtain” or “sheet “causes slipping stones or blocks to be conducted to the base of the slope as an accumulation “pocket”) and/or for the stabilization of slopes (with the marked presence of anchors distributed over the face of the slope, basing itself on the soil nailing (soil stapling), technique, associated to the isotropic membrane (MT), which acts along in conjunction with the rods and reinforcing steel cables.

BENEFITS / ADVANTAGES

* Low environmental impact solution
* 100% draining solution
* Ability to absorb deformation
* Isotropic meshes: due to the geometry of MT meshes, they have an isotropic mechanical behavior, that is, they have the same resistance in both horizontal and vertical axes. There are rhomboidal meshes available for sale, and their horizontal and vertical resistances differ, which can imply faults depending on the stress to which the mesh is subjected.

APPLICATIONS / SOLUTIONS

Slope protection
