Agricultural Cover Systems

Selecting the correct cover systems for manure lagoons, and ponds is important. Whether you’re looking for a gas-collection cover, a non-gas tight cover or a gas holder, IEC can design a custom solution just for you.


Floating Manure Basin Covers

Gas-Collection Covers

IEC’s Covers are customized to fit the geometry of your pond, lagoon or tank. Our patented gas-collection cover design includes a series of lateral floats that provide pathways for gas to flow beneath the cover to the perimeter collection pipe, and on to one or more withdrawal points.

Traditional floating covers that inflate with biogas expose the geomembrane cover to vibration and fatigue from wind, which significantly reduce the life span of the cover. IEC’s floating covers use lateral floats instead, which keeps the entire cover floating on the liquid surface, preventing exposure to wind.

Additionally, ballast weights placed on top of the floating cover channel rainwater and snow melt to sumps, which remove all rainwater from the surface.

IEC’s floating gas-collection covers have a number of benefits, including:

  • Designed by engineers with more than 25 years of continuous cover design experience
  • Accommodates fluctuation in liquid level
  • Installated with little interruption to basin use
  • Installated on tanks ponds, and lagoons of all sizes and shapes
  • Eliminates rainwater ponding problems
  • Eliminates inflation of the cover with biogas
  • Provides access to internal equipment

Modular Floating Covers

IEC’s patented Modular Floating Cover System for manure ponds, tanks and lagoons is comprised of a series of individual casings (panels/modules), which are connected together to form a complete, floating cover system. Each individual casing consists of a flexible closed-cell insulation encapsulated and sealed with an impermeable geomembrane.

The result is a unique floating cover system that controls odors, provides insulation value ranging from R-2 to R-30; and is engineered and manufactured to specific dimensions/basin requirements.

IEC’s Modular Floating Cover System offers the following advantages over conventional cover systems:

  • Low Maintenance
  • Can be installed on tanks, ponds and lagoons of any size and shape
  • Adapts to varying water levels
  • Consists of removable, individual casings
  • Installed without site interruption
