Our History


KEYMAY Industries was founded in 1995 with its patented three-piece concrete weight – the “Trilobite” – and a vision to expand into every facet of pipeline buoyancy control. Since its founding, KEYMAY has continued to expand its product and service offerings to become one of the most efficient full-service companies serving the pipeline and civil engineering industries.

Innovation and commitment to quality products and services has always been the cornerstone of our success. Since its founding, KEYMAY has been a forward-thinking company, constantly looking for new ways to improve the efficiency and performance of the products and services used by the contractors and workmen on construction sites around the world. With a continual focus on R&D and innovation, KEYMAY has developed a wide selection of patented technologies and expertly engineered products optimized for safer installation on-site and unmatched durability against other products on the market.

Through acquiring Enviro-Pro Geosynthetics in 2010, KEYMAY enhanced its service and product offerings, becoming a highly-specialized company that can help customers in the pipeline and construction sectors accomplish more with a higher level of efficiency by only having to deal with one company. KEYMAY is now a leader in international solutions for pipeline buoyancy control, including concrete and geotextile pipeline weights and screw anchors, along with specialty pipeline and engineering construction products and services for a wide scope of applications.

KEYMAY provides all-inclusive, expert application and installation services including continuous concrete coating, on-site EcoBag filling, field joint coating, integrity dig coating, and liner installation, along with qualified QC and inspection personnel. KEYMAY also provides a wide selection of geosynthetic liners, geotextiles, and other products used for sediment control, soil reinforcement, flood control, and secondary containment systems suited for oilfield construction and road building applications.

With industry-leading patented technologies, a sophisticated Quality Management System and an impeccable safety record, KEYMAY goes the extra mile to ensure your project’s success.
