Aquatic Dam Stop Leak® is a powder/granular blend of polymers. The product is broadcast out on to the surface water of the dam. It then creates a gel that is drawn into the leak where it expands and bonds with the dam structure creating a long lasting seal. This puts a stop to your leaking water.
Step 1. There needs to be water in the dam. It is best applied after recent rainfall. The water level needs to be above the area that has been identified to be treated. If you are treating the base of the dam then sufficient depth to create enough pressure to cause the dam to start to leak is required.
Step 2. The dam needs to be leaking. The leaking water acts as a carrier to transfer the product to where the leak is. The polymer gets drawn into a crack or crevice or porous area where it gets stuck and starts to expand. The expansion rates can range from 100 to 200 times their original size. As the polymer grows it creates massive blockages which constrict the loss of water.
Step 3. Although we have had feedback from clients that sealing has been achieved after 1 day we suggest maintaining a water level above the area treated for at least 2-3 weeks to the give the polymer plenty of time to hydrate and create the necessary blockages
