About Net Down System

Protect your exposed geomembrane covers, liners and geo-textiles against wind damage and displacement

The Problem:

Any exposed geomembrane cover, liner or geo-textile is at risk of wind disturbance or damage leading to complete system failure, costly remedial works, environmental non-compliance and potential Health & Safety issues.

For many years the users, engineers, suppliers and installers of exposed geomembranes have used unreliable, costly and outdated methods of ballast such as sand bags, tyres, soil windrows and ground anchors.

The Solution:

Our Net Down anchor system is a three-dimensional knitted polyethylene mat which defuses wind flows and ensures the below geomembrane cover, liner or geo-textile is left undisturbed by even storm force wind speeds.

Back in late 2006 we commissioned the world’s first trial / case study of Net Down within a temporary landfill capping application. The site (located on the sea front in Oban, Scotland) had experienced historical wind damage to exposed geomembrane caps. Please click here to view the original case study report.

Since the successful conclusion of the initial trial / case study we have supplied and installed millions of m2 of Net Down across the World.

Why use our Net Down anchor system as your chosen Geomembrane cover, liner or geo-textile ballast solution?

  • UV lifespans of up 5 years to 10 years available. Again, we have multiple project references available where our Net Down system has been successfully and repeatedly reused
  • Removes the need for large quantities of sand bags or tyres from being placed and roped which is laborious, time consuming, costly and presents obvious health & safety issues for installation personnel particularly when working on steep slopes and gradients
  • Installation time efficiency of Net Down is up to 80% quicker than the placement of other ballast systems such as sand bags and tyres
  • Provides up to an 80% UV block to underlying materials
  • Provides added durability to underlying materials
