Patented Design Floating Covers, Tank Systems, Storage Lagoon Covers and Liners

IEC, a company with 16 years experience designing, fabricating, and installing industrial cover and liner systems, designs its products to provide many years of lasting service in a variety of environments and applications.  Since 1993, the company has designed, fabricated and installed more than 250 projects involving odor control, gas collection, pond liner systems and tank liner systems.

IEC’s Odor Control & Gas Collection Covers are specifically designed for each client utilizing a variety of material options.  Cover applications can be used with any type of gas collection from water basin and keep rain and snowmelt water separate from wastewater under the cover. Advantages of a cover include installation without site interruption, use on tanks or lagoons, elimination of rainwater ponding problems, elimination of gas ballooning, provides high buoyancy and rigidity, hatches can provide access to in-basin equipment, improved quality with pre-manufactured panels and are fabricated at IEC’s plant, so field welding is not required.

IEC also has a patented Modular Cover System comprised of a series of individual casings connected together to form a complete floating cover system.  Each individual casing consists of a panel of closed cell insulation encapsulated between two sheets of durable geomembrane.  The result is a unique floating cover system that provides insulation values ranging from R-2 to R-30; and is engineered and manufactured to specific dimensions/basin requirements.

The Modular Cover System offers the following advantages over conventional covers systems:
• maintenance free
• can be installed on tanks or lagoons
• adepts to varying water levels
• individual casings are removable,
• installed without site interruption
• shorter installation time, no field welding required
• installation requires less heavy equipment
• eliminates rainwater ponding problems
• eliminates gas ballooning
• high buoyancy and rigidity
• hatches can provide access to in-basin equipment

  1. Chris Pertschi Says:

    We are turning a 130′ x 130′ lagoon into an anaerobic digester and need a flexible insulated membrane to cover it.

    Looking for at least R-5. Also the lagoon will be kept under 1/2 – 1 lb. of pressure so the membrane needs to be able to hold this pressure, and ideally be able to ‘balloon’ a little bit to hold the gas.

    Please let me know if your material might meet this criteria.

    Thanks, Chris
