EnCAP-IT was founded in 2009 in Glen Allen, Virginia, as an environmental consulting firm. Over the past twelve years we have been developing solutions to solve environmental issues for the waste, power and land development industries.

Thanks to our ability to think outside the box, we have twelve patented methods approved by the U.S. Patent and Trademark Office, with another three currently in development. For EnCAP-IT, innovation is a never-ending journey, not a destination.

When it comes to protecting the environment, we know that we can all do better.

No two landfills, dams, levees, basins are the same and have common but also distinct challenges with proper storage solutions.

From experience collected over the years (visiting over 50 facilities), EnCAP-IT has continued to develop solutions.  These innovative solutions can benefit all stakeholders.

Every site has unique challenges, but every project EnCAP-IT undertakes benefits from our foolproof approach, which is to:

  • Fix the problem
  • Exceed safety requirements
  • Protect the environment
  • Provide the lowest cost solution



Since liquid migration into traditional MSE systems could cause stability deterioration, we developed a proactive moisture eMSE system application.




Not bound by traditional design, regulatory and economic challenges, our eMSE systems are much more flexible and scalable than traditional systems.




Reuse of non-traditional construction materials avoids costly procurement of natural resources and can become a new source benefiting the owner.
