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.
