What is ROCKSHIELD MESH and How Does It Work? ( gehirneimer.de ) Englisch

I'm considering using Rock Shield For Pipeline for a pipeline protection project, but I'm not entirely clear on what it is and how it works. Can anyone provide detailed insights or experiences with this product?

From what I gather, ROCKSHIELD MESH is designed to protect pipelines from potential damage caused by rocks and other abrasive materials during backfilling and throughout the pipeline's operational life. I understand it's a type of protective mesh, but I'm curious about the specifics.

Material and Durability: What material is ROCKSHIELD MESH made from? How durable is it in different environmental conditions?
Installation Process: How is the mesh installed? Is it something that can be done easily on-site, or does it require specialized equipment and expertise?
Performance: How effective is it at protecting pipelines? Are there any studies or real-world examples demonstrating its performance over time?
Cost and Availability: How cost-effective is ROCKSHIELD MESH compared to other pipeline protection methods? Where can it be purchased, and are there different types or grades available?
