Lagoons, Reservoirs, Wastewater Pits
Above AND Below Ground Water Reservoirs
Many types of materials can be used
in the lining of these large applications,
with the most commonly used materials being:
Hypalon, PVC's, XR-5, XR-3, HDPE, LLDPE, MDPE,
Clay Liners, and Polypropylene.
Hypalon
(Chlorosulfonated Polyethylene)
An extremely durable flexible pond liner/cover
material. Hypalon liners are made from a special polymer that is compounded, fabricated
and installed in a thermoplastic state. Field installations and accelerated aging tests by
Burke Environmental Products, have demonstrated that under most conditions Hypalon liners
and covers have an extremely long service life. Hypalon synthetic rubber will resist the elements better than
any known material and is exceptionally resistant to oxidation and virtually immune
to ozone and ultraviolet light. This material is proved to be suitable for the containment
of a large variety of industrial wastes. Hypalon can also be compounded in white and
attractive light colors without sacrificing its desirable properties.
Factory seam fabrication, under controlled conditions, is done by a
precise combination of heat and pressure. Field seaming uses a bodied solvent adhesive
following a pre-wash to give equally reliable results under the varying weather conditions encountered during installation. After installation, a surface
cross-linking develops which produces a stronger, tougher and more weather resistant
liner.
PVC's
(Polyvinyl Chloride)
Liners
are fabricated for plating, agriculture, potable water storage, foodstuffs, crude oil
& fuels, hazardous materials, mining applications, acids, earthen pits, large or small
ponds, berms and sumps, with expert installation services available for storage tanks, lagoons, floor linings, sewage facilities, etc., fabricating
PVC's, Hypalon , XR-3, XR-5, Urethanes and other specialized fabrics. Materials range in
thickness from 20 mil to 3/16 thick and hold solutions up to 200 F.
Most PVC geomembranes are either black or shades of gray. Carbon black and titanium
dioxide are used to make these colors, with carbon black being an excellent UV protector, absorbing most of the UV
radiation that strikes the geomembranes, converting it to heat. Titanium dioxide reflects
almost all UV radiation, so together they offer excellent UV protection. Geomembranes can be exposed for years with minimal UV degradation.
Miscellaneous raw materials that are used in geomembranes are not necessarily in every
formula. These would include biocides, UV additives, process aids and impact modifiers.
Biocides are added to resist any biological attack that the geomembranes may experience in
the field and to meet soil burial requirements for NSF standard 54. UV additives are
added to PVC geomembranes specifically designed for outdoor exposure. Impact modifiers may
be added to improve low temperature resistance, for low temperature applications.
HDPE
(High Density Polyethylene)
HDPE is
manufactured from microbiological resistant polyethylene resins and offers optimum
chemical resistance, with weathering capabilities and stress absorption properties. HDPE
offers the best dimensional stability and resistance to stress cracking, with excellent
weld strength.
Field Lining Systems, Inc., has installed millions of square feet of HDPE in all types of
applications and you can be assured that Field Lining Systems has the experience,
knowledge and full capabilities to handle the most complex and difficult lining
assignments, with HDPE being just one of Field Lining Systems specialties.
GCL's
(Geocomposite Clay Linings)
Geosynthetic Clay Liners (GCLs) are high performance needle punched
environmental reinforced composites which combine two durable geotextile outer layers with
a uniform core of natural sodium bentonite clay to form a hydraulic barrier. Fibers from
the non-woven geotextile are needle punched through the layer of bentonite and incorporated
into the other geotextile (either a woven or non-woven). This process results in a strong
mechanical bond between the fabrics.
LLDPE, MDPE
(Linear Low Density Polyethylene & Medium
Density Polyethylene)
Low Density Polyethylene
This is a semi rigid material used for ponds, lagoons, canal liners, fire ponds, mine
trailing ponds, waste water ponds, leachate collection ponds, brine ponds, cargo covers,
interim landfill caps. Excellent protection from UV rays and harsh weather conditions. No plasticizers added. High
elongation with tremendous tear resistance and bursting strength. Minimum carbon black
content of 2.5%. Virgin resins. This is a fish safe material.
Medium Density Polyethylene
This is a light weight film mono-layer membrane
material consisting of a blended medium density polyethylene. Minimum carbon black content of 2.5% provides excellent protection from UV rays and harsh
weather conditions. Puncture and tear strengths far exceed common polyethylene or vinyl
films. This product is used mostly for ponds, including lagoons, canal liners, fire ponds,
remediation liners, cargo covers, oil field pit liners, silage covers, outdoor covers,
brine ponds, mine trailing ponds, interim landfill caps, leachate collection ponds.
This
is not a fish safe material.
POLYPROPYLENE
Polypro is a more flexible than the
LLDPE, but not as flexible as the PVC. This can be used for large and semi large
applications. Our Polypropylene contains no plasticizers that can leach out and hinder
long term flexibility and performance. Outstanding resistance to environmental stress
cracking even at elevated temperatures and in addition to aggressive chemical environments.
This is a good material for ponds, lagoons, canal liners, fire ponds, remediation liners,
brine ponds, mine trailing ponds, landfill caps, fish hatcheries, evaporation ponds, golf
course water traps and waste ponds. This product is fish safe.
XR-5 & XR-3 By Seaman
Corporation
X-R5 is not a scrim
supported flexible liner. It is instead, an extremely tough woven composite fabric
of DuPont Dacron polyester fibers that have been molecularly coated with sophisticated
compounds that are minimally degradable in adverse environments. Combined liner and coating offer a unique balance of
performance features and durability.
Liner type is used in primary and secondary containment applications and is
excellent for wastewater, brine, saltwater, oily wastes, manure, jet fuel, diesel, motor oil, kerosene, acids, cyanide, pulp
waste, landfills, brewery waste, vapor odor barrier, sewage, sludge ponds, floating
baffles, leachate ponds, substation containment, mining facilities, potable water.
X-R3 geomembrane is
specifically designed for high-performance containment and storage of waste water and
storm water, as well as bioremediation covers and mining applications. XR-3 has superior
resistance to UV radiation and harsh weather. Holds up to long term exposure without the
need to be covered. This material also has high resistance to common contaminants
present
in waste water. Comes in large pre-fabricated panels to help simplify installation
and field seaming. XR-3 comes in reinforced and non-reinforced, with the
non-reinforced stretching up to 250% without breaking.
