Common Applications for Geomembrane Liners

With BTL 30, and our line of geomembrane and specialized geosynthetics, BTL Liners has developed the most durable, dependable secondary containment systems available – and also some of the most multipurpose.
With dozens of applications for geomembrane liners possible, let’s look at some of the most common.

Agricultural

Agricultural applications for geomembrane liners are numerous and can overlap into other sections, including lagoons, irrigation ponds and canals. These applications can go far beyond containment issues. Certified NSF-61 liners are safe for plants, fish and potable water. Some of the most common agricultural applications include:

  • Holding potable water
  • Aquaculture, raising fish
  • Hydroponics – lining beds to prevent nutrient and water loss
  • Greenhouse covers
  • Haystack covers
  • Tank and cistern liners, for water as well as fuel, primary and secondary containment
  • Protecting livestock from sun and incremental weather
  • Protecting farm equipment
  • Keeping aggregate and/or grain dry

Rivers and dams

When considering river or dam management, there are several applications possible. In addition to uses based on its waterproof quality:

  • Algae ponds
  • Silt curtains for use in mining operations
  • Brine ponds
  • Containment booms for many purposes
  • Within cofferdams for seepage controls
  • Temporary cofferdam
  • Waterproof facing for dams

Stormwater management systems

Drought conditions are existing throughout the country. Stormwater retention, for use in irrigation and drinking water, can help utilize water without loss to seepage. A similar application, stormwater detention, involves the establishment of a dry pond, as a means of controlling flooding.

Geomembrane use in ponds

For commercial, industrial or residential applications, pond liners are durable, and puncture resistant. BTL Liners can create the largest single panels possible to minimize seams. Our RPE and RPP liners are fish and plant safe, and LEED certified. Some common pond applications include:

  • Algae ponds
  • Brine ponds
  • Golf course ponds
  • Lakes
  • Preformed ponds
  • Retention ponds
  • Evaporation ponds for salt recovery
  • Recreational ponds
  • Waterscape and architectural ponds
  • Koi ponds

Canals

Thousands of miles of irrigation canals exist, with more added all the time.  Most canal walls are made of concrete, clay or soil. Over time, cracks can form along the walls, allowing water to seep through.
It’s been estimated that as much as 50% of irrigation water is lost due to seepage through canal walls. Adding geomembrane liners to canals will save that lost water; which is a critical idea, especially considering drought conditions.

Roads and highways

It may seem a bit surprising to find the term geomembrane in the same sentence as roads and highways. However, there are several environmentally conscious applications available. These include:

  • Overlays as a waterproofing layer beneath asphalt
  • Protection against hazardous liquid spills from traveling underneath and around roadways
  • Pollution protection from deicing salts added to roadway

Containment

In most situations, liners are used for secondary, as opposed to primary, containment of hazardous materials. Secondary containment can prevent hazardous liquids from polluting soil and water. It also provides an enclosure to reinforce storage systems, holding materials that are toxic, flammable, reactive, combustible or corrosive. For the ultimate containment protection, choose a fire-resistant liner.

  • Oil field containment
  • Mining containment
  • Drilling site pad liners
  • Heap leach pads for fracturing
  • Storage/removal of radioactive and hazardous waste and wastewater.
  • Secondary containment of above and below ground storage tanks
  • Secondary containment of hazardous liquids in transport
  • Disposal of mill tailings from mining operations
  • Geomembrane baffle curtains
  • Lining pipelines

Lagoons and pits

Lagoon and pit liners can be used to control wastewater seepage, preventing contamination of soil and drinking water. Since lagoons and pits are both used to hold some form of waste, preventing seepage is crucial. The use of floating covers can also be used to prevent pollution (including hazardous vapor) and to collect biogas. Some of the most common lagoon and pit-related liner applications include:

  • Animal waste containment
  • Aerobic and anaerobic manure digesters
  • Floating covers for pollution prevention
  • Floating covers for biogas collection
  • Salt disposal pits
  • Oil and gas fracturing pits
  • Fire retention ponds

Landfills

Managing landfills appropriately and efficiently can be a challenge. Lining the pits can prevent seepage of waste into the soil and groundwater. Liners can also be used for redirecting rainwater away from pits, which can result in huge financial savings.

  • Lining primary, secondary and tertiary solid-waste landfills
  • Alternative daily coverings instead of daily soil covering
  • Diverting rain/snow water from pits

Tarps and covers

Additional applications for tarps and covers include:

  • Soil stabilization to prevent landslides and erosion
  • Controlling expansive soils
  • Managing frost susceptible soils
  • Evaporation control with floating covers for ponds

Vapor barriers

Moisture seeping into a building’s walls, ceiling and foundation can create structural problems. Providing a barrier to the moisture, preventing it from moving into the structural elements can eliminate the growth of mold, mildew and fungus. Vapor barriers can also prevent potentially hazardous chemicals from seeping into the soil and groundwater below a building’s foundation.

Contact BTL Liners for your next project

There are nearly unlimited applications for geomembrane liners and new uses are being discovered all the time. For example, recently, after near-record snowfall accumulated on roofs in the Pacific Northwest, BTL’s liners were put to use assisting with snow removal.

For more than 35 years, BTL has provided the best possible geomembrane and specialty geosynthetic liners to our customers for a multitude of projects. If you have a projects or applications for geomembrane liners, contact BTL.
