Long-Term Covers

Since then NWCI has the developed the most durable and cost effective line of long-term covers on the market today and our long-term cover products are used across the globe in some of the largest mission critical remediation projects in the world. With over 8 different covers designed to tackle every imaginable environment in the most cost effective manner we are sure that we have a cover for you.

ConCover SW (SuperPlus)

ConCover SW (SuperPlus) is a custom blend of HydraGuard and 180 added to a traditional ConCover SW mix which morphs our standard intermediate cover into a high quality cost-effective long term cover. ConCover SW (SuperPlus) is a patented blend of technologically advanced polymers and recycled fiber that forms an extremely durable slurry when mixed with water. When applied, it creates a uniform, encapsulating barrier that can last 8-10 months or longer. ConCover SW SuperPlus is the ‘perfect’ low cost long-term cover and has a long track record of success in remediation, landfill, and long-term erosion and seeding projects. ConCover SW (SuperPlus) is a biodegradable, non-toxic material (HMIS rated ‘0’ for health, fire & reactivity) and uses recycled materials making it the greenest & safest high-end intermediate and long-term cover material on the market today.


ConCover 180/180NS

ConCover 180 & 180NS is a patented technologically advanced  ‘Air Entrained’ Sprayable Slurry. Ideal for use as a long-term cover or as a remediation cover for suppressing fugitive dust, VOC’s or odors from contaminated sediments. The NS or Non-Setting version is especially useful when there is an on-demand aspect to when the cover needs to be applied. When ConCover 180 & 180NS is applied it creates a consistent, impervious barrier up to 3 inches (7.6 cm) in thickness that can last upwards of 12-18 months. Because of the entrained air, it can be applied to (50-60 to 1) sludge ponds to suppress odors. The NS version can be applied to sludge ponds with up to 6″ of surplus of surface rainwater. The standard thickness of ConCover 180 is 1/2 – 3/4 inch (1.27 cm to 1.9 cm).

ConCover 180 & 180NS arrive at your site as a Two-Component System, consisting of chemical ‘A’ bags and a recycled paper and wood fiber matrix blend ‘B’ bag. ConCover 180 blends are biodegradable, comprised of non-toxic material (HMIS rated ‘0’ for health, fire & reactivity) and uses recycled materials making it the greenest & safest product on the market today
