Why choose polymer over a liner when sealing your leaking dam?
Polymer is added directly to the water surface, no need to drain your dam's water. The more water the better. Application is done by hand so no need to hire an expensive earthmover to clear the dam. It's completly do it yourself. It's so easy, in most cases it can be applied in under an hour.
Liners are expensive to install with possible additional costs including pumping the water away, hire of earthmoving equipment & hiring an earthmover or the manufacturer for the installation. This can add up to thousands of dollars & time lost while you are unable to use your dam.
