PolySeam® Liner Attachment System(Patent No. 8,361,261 B2)
Exclusive PolySeam liner attachment system offers a faster, cost-effective alternative to traditional batten bar attachment. When used in conjunction with our Ethylene Polymer PVC with Elvaloy® Technology Geomembrane or HDPE Containment Liners, the patented PolySeam system replaces the maintenance and repairs needed to maintain integrity of the batten bar method of attachment—for a virtually maintenance-free system! Installs faster and is more durable than containment liners alone, saving thousands of dollars in installation costs, and it installs in the most extreme conditions.
- Delivered to your site and then cut to desired length for seaming application.
- Sections are seamed into place using traditional welding methods.
- Attachments are made from HDPE or Ethylene Polymer PVC with Elvaloy® Technology Geomembrane to tank ring walls, wall, pipe supports or any other penetration.
- Once liner transition strip is in place, the existing containment liner system is attached using our spray applied coating system to the containment penetrations.
- Note: All bonding surfaces will need to be cleaned, potentially blasted and primed prior to application.
- Easily integrates with other BCI secondary containment systems and/or water filtration solutions, such as Barrier Boom or VIPOR dewatering pump system
PolySeam Barrier Boom Oil Filtration Panels Passive Drainage System
If SPCC-compliant oil containment and filtration is required, the PolySeam Barrier Boom Oil Filtration Panels Passive Drainage System provides an innovative secondary containment solution. Using patented oil solidifying technology, the Barrier Boom panels allow rain and runoff to passively drain, but become an impervious barrier when it comes in contact with oil. Panels will immediately solidify, preventing any hydrocarbons from leaving the containment area.
Barrier Boom Benefits
- Complies with SPCC 40 CFR 112.7, U.S.D.A. Bulletin 1724E-302, Chapter 3-3.2.2 and 3.2.3, and IEEE Std. 980
- Custom designed to site specifics and PE-approved for full secondary containment
- Little or no maintenance required depending on type of install
- Service life of installed product: the life of the equipment it protects
Barrier Boom Specifications
- Estimated flow rate of up to 5 GPM per ft2 material with 1 foot head pressure
- Hydrocarbon flow rate of 0 GPM for 110% oil spill containment
- Solidifies approximately a half gallon of oil per ft2 depending on oil type, viscosity, and temperature
- UV resistance of 70% (typically covered with clean, washed stone)
- Oxidation resistance of 80%
- Contains 12 to 16 oz. of loose solidifying polymers per ft2 (unique quilting pattern prevents polymers from shifting during handling and installation)
Once considered difficult penetrations to encapsulate are now easily ENCAPSULAPED with the PolySeam System. Steel, concrete, round or square supports can be transitioned with no problem!
GC-2100 Liner System
The liner system consists of pre-fabricated panels designed in varying lengths and thicknesses to meet any dimensional and product resistance needs. During the installation process, these panels are attached together using SC-3900. This attachment method results in a thicker liner-to-liner interface of approximately 40 percent, creating a strong, seamless liner system when complete.

Tank Farm Containment Liner Systems
Ethylene Polymer PVC with Elvaloy® Technology Geomembrane liner material is well-suited for large installations, i.e. covering approximately 215,000 square feet, such as a tank farm with 2 tanks holding 3-million gallons of diesel fuel. *Elvaloy® is a registered trademark of DuPont.
Many major industries often require the storage of chemicals, petroleum products and other reactive solvents in large quantities. These materials can be held in and around storage tanks, berms, basins, reservoirs, holding ponds and other containment systems, but leaks or other failures can contaminate the surrounding environment.
Containment lining systems, which often consist of elastic or PVC liners, polyesters or hybrid polymers, can protect the storage structure from corrosion or chemical attack and contains leaks and spills.
Who Uses Containment Liners?
The oil and gas industry frequently uses containment lining systems to prevent fuel spills from leaching into the groundwater or surrounding environment. Containment lining systems are also frequently used in industries that store chemicals or hazardous waste on site. Other applications include chemical containment at petrolatum tank farms, wastewater runoff basins and water treatment and mining holding ponds.
What Are the Types of Containment Liners?
Chemical containment liners can be designed for use with primary or secondary containment systems, such as bolted or welded steel tanks or concrete vaults, tanks or ponds. Different types of liners may be needed for short-term compared to long-term use.
Containment liners can be applied in such forms as sheets or panels as well as spray coatings. Effective containment linings will fully adhere to the substrate, seal all gaps and create an impermeable barrier between the chemicals and the containment structure, whether concrete, metallic or made of another material.
Containment liners are often constructed from geomembranes, which the American Society for Testing and Materials (ASTM) describes as very low permeability synthetic membrane liners or barriers used with geotechnical engineering related materials in order to control fluid migration in a man-made project, structure or system.
Composite containment liners are often constructed using such materials as high-density polyethylene (HDPE), very flexible polyethylene, polyvinyl chloride (PVC), flexible polypropylene and ethyl propylene diene monomer. [EPA-2]
How Long Do Containment Liners Last?
Geomembrane liners for spill containment must be able to resist damage such as tears and punctures, as well as environmental stress cracking and thermal contraction and expansion. Underground geomembranes must withstand potential damage while being installed, while exposed or aboveground geomembranes must withstand sunlight, weather and surface activity.
Depending on such factors as design, material thickness, regularity of maintenance, durability and the nature of materials the liner is exposed to, liners can last several decades without needing replacement.
Alternately, a study performed durability tests in laboratory and field conditions and concluded that some HDPE geomembranes can have a potential service life of hundreds of years.
Rules and Regulations for Containment Systems
The Environmental Protection Agency is one of the primary regulatory bodies overseeing chemical containment and storage in the United States. The Occupational Safety and Health Administration as well as state and local municipalities may have additional rules codes and ordinances relevant to containment systems.
As part of the 1973 Clean Water Act, the EPA first introduced requirements for Spill Prevention, Control and Countermeasure (SPCC) for fuel and chemical storage. In 1996, an EPA report estimated that more than 80 percent of aboveground storage tanks (ASTs) did not have impervious liners as part of their secondary containment.
The EPA presents specifications in its hazardous waste storage regulation 40 CFR 264.175. This requires that secondary containment systems be impervious and free of gaps or cracks. It must have either a sloped design or a means for quick remove of leaking or spilled material. It must have capacity to contain at least 10 percent of the total volume of the primary container or 100 percent of the volume of the largest container, whichever is larger. The system must either prevent precipitation or run-on from entering or have capacity to contain it. Material leaked or spilled into the secondary containment area must be removed as quickly as possible to avoid overflow and potential environmental contamination.
Chemical containment liner systems are products vital to the prevention of chemical leaks and spills from tanks, basins and holding ponds into the environment. BCI’s containment liners offer such advantages as easy installation, high durability under heavy traffic, easy cleaning for potential reuse and few to no maintenance needs. The most effective geomembrane liners will provide the container with long-term protection from corrosion, the elements and the adverse effects of fuels and other chemicals.
