IEC | Industrial & Environmental Concepts, Inc.
About
Headquartered in Lakeville, Minnesota and operating since 1994, IEC (Industrial & Environmental Concepts, Inc.) is a global designer, fabricator, and installer of geomembrane cover and containment liner systems. Operating across four continents, IEC serves wastewater treatment plants, industrial facilities, agricultural operations, and waste-to-energy projects. The company's product portfolio centers on its proprietary Covex® floating cover platform — a modular system deployed on anaerobic digesters, clarifiers, launders, and treatment lagoons to control odors, retain heat, capture biogas, and suppress algae and evaporation. IEC extends its cover expertise to gas collection and storage covers for digester biogas recovery, renewable natural gas applications, bird deterrent covers for ponds, and geomembrane landfill caps. On the liner side, IEC manufactures HDPE and LLDPE geomembranes for pond, lagoon, and tank containment, along with geotextile and geosynthetic clay liners for secondary containment and hydraulic barrier applications. Rounding out the product line are floating and fixed baffle curtains that redirect flow and improve retention time in treatment basins, double-membrane gas holders for pressurized biogas storage, and the patented Quick-Stairs nonslip stairway system for safe slope access without puncturing installed liners.
Key Products
Proprietary modular floating cover system for tanks, lagoons, and ponds providing odor control, heat retention, evaporation reduction, and algae/animal control.
Covers designed to capture and contain biogas emitted from anaerobic digesters, lagoons, and other treatment processes for renewable energy recovery.
Specialized covers for biogas collection and upgrading to RNG, supporting waste-to-energy and co-digestion applications.
Floating covers that prevent waterfowl from landing on treatment ponds and lagoons, protecting both birds and water quality.
Fixed or floating covers for clarifiers and tanks that control odors, reduce heat loss, and prevent debris entry.
Covers for clarifier launders that prevent algae growth, reduce odor, and improve clarifier performance.
Covers for anaerobic digesters that capture biogas, maintain digester temperature, and control odors.
Geomembrane covers for landfill sites providing containment, gas collection, and environmental protection.
HDPE and LLDPE geomembrane liners for industrial containment ponds, preventing seepage and groundwater contamination.
Secondary containment liners for tanks and process areas, providing spill containment and environmental protection.
Liners for evaporation ponds that withstand UV exposure and chemical degradation while containing concentrated wastewater.
Geomembrane liners for wastewater lagoons that prevent seepage into groundwater and provide long-term containment.
Non-woven geotextile materials used for filtration, separation, and cushioning in liner systems.
Composite liners combining bentonite clay with geotextiles for superior hydraulic barrier performance in containment applications.
Floating and fixed baffle curtains for lagoons, ponds, and tanks that improve hydraulic flow patterns and treatment efficiency.
Biogas storage systems with inner and outer membranes that store digester gas at variable volumes while maintaining positive pressure.
Patented, nonslip stairway system for safe access on lined slopes, providing OSHA-compliant ingress and egress for lined containment facilities.
Cover and liner systems for manure ponds and agricultural lagoons that capture biogas, control odor, and prevent seepage.
