Caps & Covers


Geomembrane covers are generally used to protect materials from water infiltration and to prevent loss of material from erosion by wind or water. Additionally, covers can provide odor control.

Short-term cover applications include soil remediation projects, temporary stock pile covers and erosion protection on slopes in active construction sites. Long-term applications include landfill closure covers or caps. Another application is to extend the life of above-ground storage tank roofs. Nilex offers geomembrane liner installation, design assistance, fabrication and construction services for containment applications.

I want to thank you for getting things organized as quickly as you did for us and for the follow up calls and site visits that allowed us to get this work done and meet our schedule dates for the road work. As well, your product knowledge and ability to provide the technical support when dealing with the consultants was a major help in getting the system approved and installed correctly.

Not only was there a substantial cost savings realized by the client, there was also a benefit to the road structure as well. The original design road structure number was 3.780 and a calculated traffic (ESALs) of 2,147,000. The revised road structure number using the TX5 is 4.260 and a calculated traffic (ESALs) of 4,593,000.
