SITE CONSIDERATIONSWhenever possible, site selection should avoid areas where flooding or ground water pressure can occur. The lining "bottom" should be well above the water table. If the site selected is in an area where organics are in the soil, or if gases can be generated by chemical reaction, the design must allow for venting.
SURFACE PREPERATIONSSurfaces should be level and free of all sharp rocks (all rock and stone greater than .05 diameter), objects, vegetation and stubble. (Soil sterilization may be necessary to kill roots and certain types of grasses.) The subgrade surface should provide a unyielding foundation for the geomembrane with no sharp or abrupt changes or break in grade. Proper compaction assures stability and support of the liner.
CONTROLLING GROUNDWATERGroundwater should be taken into account and, if present, it will need to be controlled both during and after construction. One method for controlling groundwater is to develop a French drain system under the lining that allows the water to flow laterally under the lining without floating the lining. A good design for an underdrain is to pipe it to the outside of the lake into a gravel sump. This allows the sump to run continuously during construction and, with the placement of an upright at this sump, the underdrain can be pumped if needed to relieve hydrostatic pressure and gas buildup under the lining system.
SLOPESSide slopes should be no steeper than 3:1 whenever feasible. Contact CLI directly when site specifications or conditions differ. Slopes are usually hand-raked to achieve proper smoothness.
RECEIPT OF LINER & MATERIALSLiner panels are fabricated into large sheets to minimize field seaming. These large panels are first accordion folded, then rolled up on a core. It is recommended that the liners panels' protective covering not be removed until installation and that any uncovered panels be stored out of direct sunlight. Panels are rolled on 6" cores and can be unloaded using a 10' section of schedule 80 pipe and handling straps. We also offer 12 mil tarps to cover and protect delivered liner rolls.
ANCHOR TRENCHESTo secure the edges of the lining in an earthen pit, an "anchor trench" is dug. Anchor trenches are approx. two foot wide by two foot deep (2' x 2') and one foot back from the crest of the berm (standard trench dimensions and depth vary according to project design) Dirt removed should be raked out flat on the far side of the trench, away from the pit, to be used to backfill after the liner edges are laid out in the anchor trench, while allowing the panels to be unrolled along the berm.
SITE STRUCTURESStructures, piping, concrete, drains, and any associated work should be completed prior to lining installation.
LINER DEPLOYMENTThe roll is raised by a loader, forklift, or other lifting equipment, and then unrolled in one direction, and unfolded in the other direction.
PANEL PLACEMENTTake time when unloading and placing rolls of lining to avoid damage. Verify the location of a panel or sheet before unrolling and placement to avoid improper alignment. Sandbags are required to keep the panels in place during installation, exposed or covered. Care should be taken to avoid wrinkles in the seam areas and around mechanical attachments. It takes considerable manpower to deploy a liner. It is "pulled" but not stretched. Minor wrinkles insure the liner is installed in a relaxed condition. A ballast system (sand bags) and anchor trenches are used for all geomembrane installations.
FIELD SEAMINGFabricating panels at one of our climate controlled facilities into essentially larger panels dramatically reduces the amount of field seaming a project requires. The lining material itself determines the types of field seaming techniques used. The most commonly used process is heat fusion welding, which can be done with hot air or hot wedge.
LINER ATTACHMENTS TO STRUCTUREThe most commonly used methods for attaching to structures are Mechanical and Embedment Strip methods.Mechanical: Battens are typically 1/4" x 2" and are aluminum or stainless. (Pending corrosion resistance requirements.)Embedment Strip: A method using the same material as liner system - placed in concrete during concrete pour.Creative methods to deal with special attachment needs are possible.
PIPE BOOTSA pipe boot is a method of sealing the liner system to necessary pipes that penetrate the lining system. These can be fabricated in one of our facilities or on site during field construction.

PC Strands are used in prestressing of concrete railway sleepers. They are manufactured in confirmation with IS 6006 - 1983. "Sleeper" is an essential and vital component of railway track. PC strands are manufactured from high quality of steel of tailor made chemistry, drawn to achieve a tensile strength of 1800 N/mm2. Wires are stranded to achieve perfect length and mechanical properties - tensile strength, proof stress, elongation and relaxation.
Advantages Gabions have a number of advantages over other types of construction materials, particularly for installations on unstable foundations.
Are made from polypropylene fibres that are tangled together in a needle-punching process. The fibres may be made in continuous or short lengths and achieve their strength by interlocking. Needle-punched nonwoven geotextiles have excellent water flow rates and are used for filtration of soil fines. Needle-punched nonwoven geotextiles have been used in drainage applications including trench drains (also known as french drains), as a wrapping for perforated pipe, for erosion protection, for the separation of a roads sub base and base course, and combined with three-dimensional structures to create prefabricated drains. They are also commonly used with geomembranes to provide a protective cushion. Needle-punched nonwoven primary functions: filtration; separation; protection; drainage
Mattress Spring Wires are cold drawn wires made from unalloyed high carbon steel. These wires are used for the manufacture of cold formed helical springs, spring rings and wire forms which find application in automobile, cycle and other industrial equipments. These wires are generally supplied in phosphate and oiled condition. We can supply wires to specific customer requirement within the specifications .
APPLICATIONS
Single Wall Corrugated HDPE Drainage Pipe has kept farms, internal bonding in post tensioning of tendons in Prestressed concrete in projects such as bridges, flyovers, offshore platforms, Via ducts, tunnels, underpasses , golf courses, parks and playing fields dry for decades by channeling away excess underground moisture.
Users find it to be an economical, easy–to–install solution to all kinds of residential storm water drainage problems: downspouts run offs, foundation and window well drains, driveway culverts and wet spots on the lawn. Single Wall HDPE pipe is also used for highway edge drains, culverts and other construction applications where economy and durability are important.
