Geomembrane Technologies' covers and liners are designed to:

  • Collect and store biogas to be converted into green energy
  • Control odors and temperature fluctuations
  • Block sunlight to control algae growth
  • Reduce contamination and disinfection by-products
  • Protect the environment through safe containment

We work with all our customers to truly understand their needs so that we can suggest the appropriate solution. By having the same team dedicated to fabricating, installing, and maintaining most of our products, Geomembrane Technologies can build a genuine rapport with customers and offer a unique, personalized experience. We can also assure that high-quality standards are met throughout all stages of the project.

Geomembrane Technologies' variety of cover options help contain odors from primary clarifiers, aeration basins, equalization tanks, and digesters by covering the exposed surfaces.

The following cover options effectively control odors and carry the additional benefit of capturing biogas for green energy recovery:

  • Structurally Supported Covers
  • Suspended Covers
  • Gas Collection Covers
  • Modular Covers

Converting biogas into valuable green energy has been a cornerstone of Geomembrane Technologies' business for over 30 years.

Our gas collection covers reliably capture biogas produced by anaerobic treatment of waste so that it can be used as a renewable energy source. To complete the system, Geomembrane Technologies offers biogas control systems  to take the biogas from the cover to energy recovery equipment.

We also offer innovative gasholders to safely store and regulate biogas from anaerobic digestion.

Excessive algae growth can throw even the best water treatment processes out of balance. Algae can clog intake screens, fluctuate pH levels, increase chlorine demand, and negatively affect the taste and smell of water. Temperature is better controlled and maintenance associated with algae cleaning is simplified. The results? Better water treatment and lower operating costs.

Several cover styles can be used, depending on the application.

  • Structurally Supported Covers
  • Suspended Covers
  • Modular Covers
  • Gas Collection Covers

Geomembrane Technologies provides insulated covers to protect against process heat loss and cold temperatures. 

The trained staff can entirely customize your solution based on heat retention requirements. We perform heat loss calculations to determine the optimum insulation thickness of all our cover solutions. Thermal protection is usually a complement to other cover functions such as biogas collection.

Cover types that offer thermal protection include:

  • Gas Collection Covers
  • Structurally Supported Covers
  • Modular Covers


Geomembrane Technologies proactively takes steps to protect both our staff and yours. We follow detailed safety procedures in both our fabrication shop and during field installation for continued safety.

All of our products are designed to be safe for the end user. Our floating covers are especially designed to support foot traffic safely and our structurally supported covers include a guardrail option for added safety. Our biogas control systems alert operators of unsafe operating conditions in real-time so that workers remain safe.

Geomembrane Technologies regularly holds tool box meetings to keep health and safety top of mind. Our team has received extensive training on many safety measures.
