We Build Relationships

Our customer relationships range from Fortune 500 investor-owned global companies to small, local and privately-owned companies.



Since our first customers, we have completed more than 2,000 projects across the United States involving a wide-range of companies and industries.  We are very proud of our achievements of business growth while maintaining long-standing relationships with the most recognized companies in their industries. In fact, our first customers remain valued customers today.

Our large global customers have helped us institute processes, systems and controls that provider a safer workplace, improved efficiencies and quality. Likewise our ongoing business with smaller local and privately-owned companies focus us on personal problem solving and relationship building skills. Having a diverse set of customers like this not only helps our business grow, but also places greater demands on us to learn, grow and improve.  We accept and immerse ourselves in the challenge to improve everyday – the result of which continues to be shown in our safety, performance, quality record and ongoing business growth.

Whether through national contracts or competitive bids, we have safely constructed hundreds of high-quality projects to repeat customers throughout the United States.



Our national contracts with scale customers provide transparency in material sourcing and certainty in project performance that benefits both parties.  These national contracts, referred to as Limited Service Agreements, provide specific material pricing, labor rates, and installation rates on a square foot basis, with payment terms and other elements that are mutually negotiated.  Under these agreements, our customers manage the coordination between ESI and the earthwork contractor as required for the given project.

Competitive bids are requested for specific projects and in most cases are led by an earthwork contractor working as a general, or prime contractor.  ESI would therefore provide bids for the liner materials and/or installation  to the general contractor for the project.  In limited cases, site owners may only need liner materials and/or installation, thereby requiring a bid directly from ESI.  In competitive bid situations, material and installation pricing are dependent on market conditions and project scheduling.

Our relationship is based on trust.

Customers have trusted us for years to deliver high-quality projects, safely, on-time, with integrity.  Examples of a few customer testimonials are featured on our news page but more detailed customer and project references can be provided on request.  Please consider using our contact form to request a more complete project list and customer references.
