Geomembrane Installation Guideline

Site Consideration tailings pond liner

Whenever 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 aloow for venting.

Surface Preparation tailings pond liner

Surfaces should be level and free of all sharp rocks(all rocks and stone greater than 0.05diameter),objects,vegetation and stubble.(Soil sterilization may be necessary to kill roots and certain types of grasses.)

The subgrade surface should provide an unyielding foundation for the geomembrane with no sharp or abrupt chanages or break in grade.Proper compaction assures stability and support of the liner.

Groundwater Control 

Groundwater 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 drain system under the lining that allows the water to flow laterally under the lining without floating the lining.

Slope

Side slopes should be no steeper than 3:1 when feasible.

Receipt of Liners and Materials 

The geomembrane is fabricated into large rolls (at maximum width 7m) to minimum field seaming.

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.

Anchor Trenches

To secure the edges o the lining in an earthen pit,an”anchor trench” is dug.

Anchor trenches are approx.1.5m away from the pond edge.(standard trench dimensions and depth vary according to project design.)

The trench itself should be free of loose soil and rocks.

Site Structures

Structures,piping,concrete,drains,and any associated work should be completed prior to lining installation.

Liner Deployment

The roll is raised by a loader,forklift,or other lifting equipment,and then unrolled in one direction,and unfolded in the other direction.

Panel Placement 

Take 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 attachment.

(Note: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.)

Field Seaming landfill geomembrane

When the lining material is High density polyethylene ,the most commonly used process is heat fusion welding,which can be done with hot air or hot wedge.

Pipe Boots

A pipe boot is a method of sealing the liner system to necessary pipes that penetrates the lining system.
