DRILINE® SMOOTH - applications

Our high density polyethylenegeomembranes are the most widely used product for lining of solid waste sites, mines, effluent, sewerage and other fluid containment applications like tanks, dams, canals and tunnels. This product is ideal for sites requiring low permeability and exceptional chemical, ultraviolet and heat resistance properties. Resistance to weather, ultraviolet rays and chemicals makes its use a cost-effective alternative in reservoir construction which is meant to be exposed to the UV and heat of the sun.

Applications

Application: Irrigation Channels

The heap leach method of mineral extraction using sodium cyanide has resulted in low cost extraction of minerals (gold, silver, and copper) from low grade ores. Polyethylene geomembranes are used as an impermeable flexible barrier to prevent contamination of the soil and groundwater by the chemical extraction solutions as well as recapturing and recycling of the solutions.

Application: Heap Leach Mining

Polyethylene geomembranes provide an excellent alternative to or supplements concrete and compacted earth in canal linings to reduce substantial seepage.  The geomembrane offers an expedient method to repair existing deteriorated concrete linings or to line new irrigation canals.

Application: Landfills

A critical element in the proper functioning of a landfill containment system is the lining system. The use of geomembranes on the bottom and sides of a landfill as an integrated leachate collection system and a leak detection system has been considered necessary for many years.

Polyethylene geomembranes, resistant to most wastes, are used as an impermeable, flexible barrier to prevent leachate from entering the environment. Leachate generally is the result of interaction of landfill moisture with contaminated waste.  Polyethylene geomembranes are used in hazardous and non-hazardous landfills.

Application: Reservoirs & Ponds

The need for water containment has grown rapidly during the last years.  Public awareness of the ecological impact of aquaculture effluents, the concern for preventing groundwater contamination, the practice of water conservation and the control of disease causing organisms are just a few of the reasons for water containment. Water reservoirs require appropriate barriers to contain the liquid - hence the need for a high quality lining system.

A major use of high density polyethylene geomembranes is in the area of liquid containment.  The geomembrane acts as a pond liner to prevent contaminants from entering groundwater sources or streams.  In addition, the geomembrane prevents loss through seepage thereby conserving millions of gallons of water annually.  Typical applications include earth reservoirs containing from potable to hazardous liquids, leachate dams, sewerage dams and water features (golf courses and resorts).

Application: Tunneling

All of today's modern tunnels utilize lining systems with waterproofing membranes. The most widely used configuration, concrete/membrane/concrete, is employed for almost any type of tunnel construction.  During construction the outer layer of concrete holds the tunnel open until the waterproofing membrane can be installed. The inner layer of concrete, which acts as the main structure of the tunnel, is then placed over the membrane.

Our black or black/white coextruded polyethylene geomembrane (primarily linear low density or a coextruded polyethylene) provides a smooth, uniform, flexible waterproofing membrane with an excellent puncture, rodent, and micro organism resistance.  The result is a dry
tunnel, reducing maintenance cost and extending its useful life.
