Polymer granules for sealing dams
Damseal is a blend of high molecular weight polymers that when applied to dry dam walls, seals the surface to stop water seeping into the walls.
Damseal is applied to empty dams to reduce or eliminate seepage loss. Damseal is applied during dam construction to ensure that leaks won’t occur after completion.
Most dams have a certain amount of water loss due to seepage, so it is recommended that Damseal is applied to all dams exposed surfaces prior to filling with water to prevent leaks and to conserve water.
