ABSTRACT:
A method for removing trapped gases such as air under a pond liner comprising partially filling the pond excavation under the liner with a liquid such as water thereby floating the liner on the liquid and collecting the trapped gases between the surface of the liquid and the liner, progressively filling the pond on top of the liner with another liquid such as water thereby forcing the trapped gases beneath the liner to the sides of the pond and venting the gases up the sides of the pond to the atmosphere, and draining away the liquid under the pond liner thereby settling the liner onto the bottom of the pond excavation.
