Why Utilizing a Spill Containment Liner Is Necessary

Posted by Felon Wilson on Apr 17, 2019 3:44:00 PM

You may be wondering why you need to worry about installing a chemical/hydrocarbon-resistant liner to catch spills. After all, if you already have a permanent, above-ground tank or a portable spill unit, the chances of the geomembrane receiving a large spill are very low. Further, the spill may be cleaned up within a short period of time.

Protect the Environment With Wastewater Impoundment Liners

Posted by Alan Strecker on Apr 5, 2019 9:51:00 AM

Government agencies, utilities, and industrial customers are increasingly relying on geomembrane solutions 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.

Water reclamation is a vital part of the services provided by government and water agencies. The public demands it be done correctly.

Differences Between Unreinforced and Reinforced Geomembranes

Posted by Kyle Wheeler on Mar 20, 2019 8:50:00 AM

When specifying a geomembrane, engineers have two high-level options: reinforced or unreinforced geomembranes. Both types of geomembranes have unique properties that make them the best solutions for certain applications and projects. In order to assist you with the specification process, we’ve broken down some of the key components for both geomembranes below.

Benefits of Using Embedment Strips to Attach Geomembranes to Concrete

Posted by Alan Strecker on Jan 15, 2019 10:00:00 AM

Nearly all geomembrane installations are fixed at the perimeter of the containment by burying the liner in an anchor trench or by attaching it to concrete (i.e., a collar wall, foundation wall, etc.). The standard approach for connecting the geomembrane liner to concrete is to use a batten.

In this technique, concrete lags are set (i.e., drilled) into the concrete. These are placed on 6" or 12" centers at an engineer’s discretion. A compressible material such as Neoprene or butyl tape is then placed between the liner and concrete, and stainless steel, like 316 SS, or aluminum batten strip, is placed over the liner, and the lag bolts are driven through the batten, liner, and anchored into the lag. The top of the detail is then sealed with a waterproof caulk (see Figure 1).

Factory Vs. Field Geomembrane Seams: What’s the Difference?

Posted by Bill Shehane on Dec 13, 2018 1:40:22 PM

Typically there are two types of geomembranes: flexible membrane liners and rigid geomembranes. With flexible geomembrane liners, large panels can be prefabricated in a factory prior to being delivered to a job site. Rigid membranes, on the other hand, need to be shipped to job sites before their geomembrane seams are joined together. So what difference does it make?

Benefits of Using EPS Geofoam for Highway Construction

Posted by XR Geomembranes on Oct 31, 2018 3:01:00 PM

Every year, more and more roads and highways are constructed to meet growing demands. However, this new construction or expansion of infrastructure may end up being built over loose or soft soil that does not have the ability to support the associated loads. So how do you reduce the vertical stress of these projects on the soil below? One solution is by using expanded polystyrene (EPS) geofoam.

Exposed Geomembrane Covers—the Rest of the Story

Posted by Felon Wilson on Sep 14, 2018 8:36:00 AM


The geomembrane industry has been buzzing lately with a new interest in geomembrane covers which are left uncovered. It’s advantageous in some situations to leave a rain-shedding cover, over a closed waste or another site, uncovered, at least for some extended period of time. This allows the owner/engineers to perform various in-situ treatment of the underlying material, make modifications to the geomembrane cover, and/or leave the site available for new or anticipated technological advances for long-term site management.

This past June, Seaman Corporation’s Geomembrane group participated in PennTec, the 90th Annual Pennsylvania Water Environment Conference and Tradeshow in Hershey. This group is affiliated with the Water Environment Federation (WEF) and includes many members who are also members of the Pennsylvania Section of the American Water Works Association (PA-AWWA). On display were XR-5® Geomembranes used for wastewater and potable water applications.

What Ensures Longevity in a Cold Environment Geomembrane Application?

Posted by Felon Wilson on Jul 26, 2018 1:32:27 PM


Some of the harshest environs in the world are in extreme cold applications. Wastewater operations must be designed with materials and features which ensure those successes. Let’s take a look at one such installation, the 6-acre geomembrane lined wastewater impoundment at the Lowell Point wastewater treatment plant in Seward, Alaska. The reinforced ethylene copolymer has been in service at the facility for over a quarter of a century. Here are five features of the original site design, product selection, and installation, which were essential to its success and longevity.
