INSTALL POND LINING

POND RESERVOIR LINERS 02666 - 5

G. Proceed with installation only when existing and forecasted weather conditions permit placement and seaming of geomembrane to be performed according to manufacturers' written instructions and warranty requirements. Do not place or seam geomembrane during conditions of precipitation, excessive atmospheric moisture, blowing dust, strong wind, or at temperatures outside manufacturers' recommended range.

H. Prepare surfaces of construction penetrating through liner according to liner manufacturer’s written instructions. Remove curing compounds and coatings from concrete surfaces to be sealed to membrane liner.

I. Field Seams: Comply with liner manufacturer's written instructions. Form lapped seams by lapping edges of panels 5 inches, unless instructions require a larger overlap. Wipe contact surfaces clean and free of dirt, dust, moisture, and other foreign materials. Use solvent-cleaning methods and grind geomembrane seam surfaces if recommended by liner manufacturer. Proceed with seaming at required temperatures for materials and ambient conditions. Continuously bond sheet to sheet to construct single or double seams of width recommended for method of seaming used. Seal or fuse free seam edges as instructed. Inspect seams and reseal voids.

J. Before initial filling of ponds, placement of earth or other cover, inspect seams and patched areas to ensure tight, continuously bonded installation. Repair damaged membrane and seams and re-inspect repaired work.

K. Liner Repairs: Repair tears, punctures, and other imperfections in liner field and seams using patches of liner material, liner-to-liner bonding materials, and bonding methods according to liner manufacturer's written instructions. Apply bonding solvent or weld to contact surfaces of both patch and liner and press together immediately. Roll to remove wrinkles.

L. Underdrain Installation: Excavate trench to lines shown on drawings. Place geotextile fabric in trench prior to installing perforated pipe and gravel The width of the geotextile fabric must include sufficient material to conform to trench perimeter irregularities and for a 6-inch minimum top overlap.
