Facility Closure and Post-Closure

When a facility has reached capacity, S+G has the expertise to design and implement a closure system that is effective for the short and long-term. S+G personnel have provided closure design and quality assurance for over 170 acres of landfill.

S+G also provides post-closure care monitoring including cover inspections and environmental monitoring. To enhance recovery and limit environmental degradation, S+G has designed plans for mining of unlined landfills.

Our landfill closure innovations  include:

  • First membrane exposed cap
  • First implementation of a “rain gutter” drainage system on a cap
