Six Geomembrane Properties You Must Consider for Geofoam Road Construction Projects

Posted by Kyle Wheeler on Jan 4, 2018 2:17:08 PM

When choosing the correct geomembrane for geofoam coverage in road and bridge construction applications, there are six properties you always need to take into consideration: 

1. Puncture Strength/Abrasion Resistance

2. Tensile Strength

3. Flexibility

4. Vapor Transmission

5. Toughness

6. Chemical Resistance

How Does a Geomembrane Hold Up 18 Months After It Is Installed?

Posted by Felon Wilson on Dec 28, 2017 10:03:42 AM

In April 2016, I wrote about what I learned watching a geomembrane installation at the World’s Fair Park Lake in Knoxville, Tennessee. Those lessons were fundamental, such as the importance of a stable and well-prepared subgrade, why you should minimize field seams and the ability to get a flexible geomembrane to fit a serpentine basin. Now, it is over 18 months later and I checked on the working installation and can offer five observations:

Geomembranes Meet a Variety of Needs for Railroads

Posted by Bill Shehane on Dec 14, 2017 2:07:32 PM

Geomembranes have played a key role in keeping railroads compliant with environmental regulations for a number of years, most prevalently in the role of spill containment in rail yards.

Containing fuel spills and chemical discharges is mandated by parts of the Clean Water Act—specifically the National Pollutant Discharge Elimination System (NPDES) and the Spill Prevention, Control and Countermeasure (SPCC) regulation.

High-Performance, Flexible Geomembranes to Meet Your Arctic Requirements

Posted by Sue Uhler on Nov 28, 2017 4:13:22 PM

In the coming years, Alaska, the Arctic, and similar cold weather regions are expected to play a major role in supplying future energy needs for the world. As energy resources continue to be pursued in these extreme climates to meet the energy demands of society, protection of our natural resources is essential. Primary and secondary containment must keep pace with the energy - technology platform to guard against contamination of our environmental assets.

Seaman Corporation looked to the XR-5® geomembrane technology for development of high-performance, low-temperature geomembranes to protect our resources in these rigorous conditions. XR-5 geomembranes have provided protection of the environment for over 30 years in ambient climates. The transition of the XR technology platform into the Arctic geomembrane arena was imminent. In Figure 1, XR Arctic membranes offer superior performance properties in their respective markets.

Geomembranes Used on Wastewater Treatment Plants Provide Sustainable Solution

Posted by Alan Strecker on Oct 31, 2017 10:09:11 AM

Wastewater treatment plants often utilize geomembranes to help protect the environment and maximize resources. In San Diego County, the Olivenhain Municipal Water District (OMWD) treats up to 34 million gallons of wastewater each day. The treated water is provided to the community through 45+ miles of recycled water pipelines. With a seasonal increase in rain, the demand for recycled water drops off and the treated water is stored in a wet weather pond.

Geomembranes Can Meet Challenging Demands to Protect the Environment

Posted by Alan Strecker on Aug 3, 2017 10:10:19 AM

Government agencies, utilities and industrial customers are increasingly relying on geomembranes for projects that could potentially threaten the environment. Cost-effective due to their ease of installation and proven to be reliable for decades, geomembranes have become a popular front line in protecting natural settings.

Environmental jobs are particularly sensitive because getting it wrong can be costly. Spills or failures can lead to long-term environmental damage, public health consequences, severe fines, and negative PR, among other issues.

Impoundment Liners – Which One Is Right for Your Application?

Posted by Sue Uhler on Jul 31, 2017 11:41:25 AM

Geomembrane liners are often used in impoundments to prevent the migration of wastes out of the impoundment to the adjacent subsurface soil, groundwater or surface water. Impoundment liners are used significantly in the energy industry to contain fresh water and wastewater, drilling waste, evaporation pits, and coal ash. Geomembrane liners used in these types of applications are made from a wide range of polymeric materials and different types of constructions, so how do you choose the right one for your exact application? In order to prevent contamination of the surrounding environment, careful consideration must be given to determine the best high-performance geomembrane liner that meets the precise requirements of the impoundment.
