Erosion Control Systems installs and repairs geomembrane liner and fabric-formed concrete.
PVC Poly Vinyl Chloride Geomembrane Liners
Poly Vinyl Chloride (PVC) is the most commonly specified lining material in the industry. Manufactured by the calendaring or extrusion process, it is a highly flexible, non-reinforced, cost-effective, waterproofing geomembrane with many uses and advantages for the user.
PVC has high puncture strength and excellent abrasion resistance. It is resistant to several industrial chemicals. Because of their high flexibility, PVC liners readily conform to subgrade contours and offer excellent interface friction without being textured. The use of a PVC liner prevents contaminants from entering groundwater sources or streams. Additonally, it helps conserve potable water resources by preventing seepage loss.
Fabrication of PVC Geomembrane Liners
Factory fabrication eliminates up to 88% of field seaming. PVC can be fabricated into panels up to 25,000 square feet in climate-controlled manufacturing plants and then shipped to the installation site. Using prefabricated panels makes it possible for crews to install acres of lining per day and reduce overall construction time.
Erosion Control Systems of Florida can custom fabricate panels to fit site-specific dimensions and requirements and provide our customers with detailed panel layouts for ultimate placement. Panel sizes are often determined by the material weight and site conditions.
Installation of PVC Geomembrane Liners
PVC supports diverse field seaming capabilities (thermal fusion by hot air wedge welders or chemical adhesives).
With advanced technology in field welding, wedge welders that apply heat and pressure to form a homogenous weld are becoming sophisticated. Wedge welding provides excellent seam properties and reproducible welds and is faster and cleaner than solvents.
A PVC liner can be easily installed by unrolling and unfolding the liner into the pond and seaming the panels using adhesives or wedge welders. Your liner can be installed using customer-provided labor and Erosion Control Systems supervisor and welders or in a turnkey installation provided by one of Erosion Control Systems professional, certified crews.
PVC must be covered with a minimum of 12″ (1 foot) of clean fill to function as designed. In buried applications, PVC can provide a service life of over 20 years.
Slopes should be limited to 3:1, and cover soils should be walked in from the bottom of the pond to the top, always keeping a minimum of 12″ of clean soil between your equipment and the membrane.
For larger ponds and lakes, erosion and wave action should be taken into account. The use of riprap, concrete shore protection, or synthetic erosion control protection is highly recommended.
PP - R
Reinforced Polypropylene (RPP) Geomembrane Liners
Reinforced Polypropylene (RPP) Geomembrane is a heat-weldable polyester-reinforced sheet designed for floating covers and liners in potable and industrial water containment applications. The membrane is specifically formulated for long-term use in buried or exposed geomembrane applications. The membrane is based on a UV-stabilized polypropylene copolymer that does not require either polymeric or liquid plasticizers to maintain flexibility.
Fabrication of Reinforced Polypropylene Geomembrane
RPP is heat welded under controlled conditions into panels at a fabrication facility. It is available in 36 mil, 45 mil, and 60 mil thicknesses. Erosion Control Systems of Florida fabricates RPP in panels of up to 20,000 square feet.
Installation of Reinforced Polypropylene Geomembrane
Erosion Control Systems of Florida installs RPP using heat fusion welding equipment, with a high-quality lining system.
RPP is an environmentally friendly material available in tan, black, and white colors without sacrificing any of its desirable properties (colors are special order with a minimum sq. purchase). This product is also manufactured and is available upon request in an unreinforced product line (UPP).
Unsupported Polypropylene Geomembrane
Unsupported Polypropylene Geomembrane products are exceptionally flexible geomembranes that incorporate high levels of ethylene propylene rubber into polypropylene. These membranes provide outstanding resistance to environmental stress cracking even at elevated temperatures and in aggressive chemical environments. The PP Series is available in thicknesses of 20 – 40 mil, and in panels up to 33,000 square feet.
Unsupported Polypropylene Geomembrane Uses
Polypropylene geomembrane liners offer superior performance for all aspects of lining lagoons, ponds, or other impoundments, floating covers, and similar containments. High-performance Polypropylene provides the end-user with an optimum state-of-the-art liner material that is also user-friendly.
XR-3 & XR-5
XR-5 & XR-3 Geomembranes
XR-5 & XR-3 Geomembranes are utilized for a variety of containment applications. XR resin is formulated for ultraviolet and ozone resistance and is an excellent geomembrane to use in an exposed environment. Covering the geomembrane with geotextile, and then covering the lined area with an appropriate backfill material will extend performance life.
An XR-5 geomembrane is also resistant to a wide range of chemicals and specifically formulated for hydrocarbon exposure. This particular geomembrane is typically deployed in various sized projects and is widely used for secondary containment in tank farms and industrial operations. Seaman also offers XR Membrane material that is specifically formulated and NSF tested for potable water applications.
XR-3 & XR-5 geomembranes can be fabricated in panel sizes designed best to fit your specific project's installation plan. XR-3 & XR-5 geomembranes are scrim-reinforced to provide excellent puncture and tensile strength properties. Fabrication of large panels allows for rapid deployment over large areas in a relatively short period.
The installation of an XR-3 & XR-5 geomembrane must be accomplished with specialized seam welding equipment in trained technicians' hands. The testing of seams also requires various testing apparatuses designed to assure that a quality installation is achieved.
The seam type determines the actual test to be performed. Seams are made with wedge welders on long and straight field seams, and extrusion or “hot-air” welders are utilized for detail seams, pipe boots, etc. An XR membrane must be installed by experienced technicians familiar with inherent factors related to this particular geomembrane.
Welding methods and parameters, quality control procedures, testing procedures, and installation documentation are important elements to assure that a quality installation is achieved.
All XR Geomembrane products are classified as an Ethylene Interpolymer Alloy (EIA). It is available in high strength, chemically resistant XR-5 Grade for maximum resistance to high temperature, and broad chemical resistance, including acids, oils, and methane.
HDPE Smooth and Textured
High-Density Polyethylene HDPE Geomembrane Liners
High-Density Polyethylene HDPE exhibits excellent mechanical properties because of its crystalline microstructure, which is why it is the most widely used and trusted polymer globally to manufacture geomembrane liners.
Exhibiting outstanding chemical resistance, UV resistance, tensile strength (it stretches to seven times its own length) and heat resistance, our range of HDPE liners are supplied with up to a 20 year prorated product warranty in certain applications.
All of our geomembrane liners contain a finely calibrated combination of antioxidant additives, stabilizers, and UV-resisting carbon black to meet strict, international quality criteria (American Society for Testing and Materials and the Geosynthetic Research Institute).
Benefits of HDPE Include
Geosynthetic Clay Liners
Geosynthetic Clay Liners (GCLs)
Geosynthetic Clay Liners (GCLs) are geotextile and bentonite composites (typically sodium bentonite sandwiched between two layers of geotextile) engineered for various environmental containment applications. The geotextiles offer a long-lasting resistance to physical or chemical break-down in harsh elements, while the bentonite’s high swelling capacity and low permeability provide an effective hydraulic seal.
GCLs provide an excellent alternative to conventional Compacted Clay Liners by replacing a thick section of compacted clay with a thin layer of pure sodium bentonite. Benefits include easy installation, better hydraulic performance, and resistance to varying weather conditions. Installation for most GCL projects can be completed by construction personnel using conventional equipment. GCLs also have unique self-sealing attributes, reducing the risk of failure due to adverse field and operating conditions.
