With the closure of any landfill or installation of GCCS, proper post-closure maintenance becomes more critical than ever. Oasis maintains a staff experienced in all facets of landfill construction and are knowledgeable in vegetation and fertilization.  We also have the equipment necessary to mow the closed landfill in an efficient and safe manner that will avoid damaging the cap, surface drainage components, and gas system components.  Oasis will work with the owner/engineer in the identification of problem areas discovered during routine and quarterly post-closure inspections to solve any issues early on and to assist the owner with cost-effective solutions.
