There are several phases of preparation of landfill base liners, starting with the positioning of the membrane, until these can be covered with several metres of refuse. These membranes may be damaged during preparation, but can also be inspected and repaired. It is advisable to undertake inspections at regular intervals.
lEC works closely with engineers and contractors on the design, layout and installation of landfill caps and leachate liners. Our experienced crews have successfully installed geomembrane in some of the most challenging basins and shapes and in some of the harshest conditions around the world.
Our fleet of trucks, trailers and equipment are designed to meet virtually any need. We test every weld and record the results for full accountability and quality assurance, which provide our customers with specific locations and corresponding test results.

Unlike base liners, surface liners are not buried at some point under many metres of waste and instead are usually protected over the course of many years only by a 1-metre thick mineral layer. As a result, there can be uncertainty about the integrity of their leak-proofing characteristics, particularly if the land is subsequently used for other purposes; however, at the same time, repairs are also possible at reasonable cost if the location of any damage can be established.
It is also possible to retrofit a monitoring system in existing surface sealing liners without impairing the synthetic liner sheet or the immediately adjacent functional layers. For this purpose, cable trenches must be dug in the recultivation layer above the drainage layer. The detection cables are then laid in these trenches.
Geotextiles enhance both drainage and lining systems in environmental applications. In the large industry of waste containment, geotextiles are used to protect and cushion landfill liners and landfill capping systems, and they are used as critical components of geocomposites such as geocomposite drains and geosynthetic clay liners. Heavyweight, needle-punched nonwovens are use as cushion/protection for landfill and pond liners to keep adjacent stones in overlying or underlying drainage layers from puncturing the impermeable liner.

Manufactured synthetic lining products have allowed for efficient design and construction of containment structures such as ponds, lagoons, landfills, tanks and secondary spill containment facilities, including vapour management systems. Because of the wide variety of project conditions and materials being contained and with so many liner types to choose from, the design and selection of the appropriate lining materials can be a complex task.
With over 25 years of experience in geomembrane containment technology, Nilex offers design assistance, fabrication, installation and construction services for containment applications. The Nilex containment technology process involves compatibility testing and the consideration of facility design and climatic factors.
Nilex professionals will work with the owner, engineering consultant and the general contractor to ensure the optimum design with the most efficient and cost-effective installation for the containment application.

High-Strength Protection of Geomembrane Liners. As a protective cover for geomembranes for closure caps and stormwater ponds, the GEOWEB system prevents liner damage and degradation. With infill confined in the GEOWEB system, slopes can be designed steeper while maintaining strength and integrity, even when subjected to settlement - common in landfills. The landfill cover system can be designed as a vegetated, aggregate armored, or concrete solution that remains flexible. GEOWEB liner protection is a ‘complete solution’ including integral tendons and ATRA tendon load transfer clips.
