Waterborne Application
(sample specifications)

A waterborne application of ESS-13 can be used on top of any existing lining method if the pond is losing between 1/2 inch and eight inches of water per day. Seepage problems with PVC, native clay, sand and bentonite can be solved with this method. ESS-13 works exceptionally well on ponds lined with concrete, gunnite or shotcrete.

A waterborne application of ESS-13 to existing bodies of water usually requires one gallon of ESS-13 to each 2,000 gallons of water. Prior to the application, a staff gauge or yardstick should be driven into the lake and the loss in vertical inches measured for 24 hours. This should be done at the full water level. Maintain the full water level for 72 hours after the treatment. Then take another 24-hour loss measurement. The comparison will give you an initial seepage rate reduction.

THE DRUMS OF ESS-13 MUST BE STIRRED BEFORE APPLICATION TO ASSURE INGREDIENTS ARE PROPERLY MIXED. Apply the ESS-13 wherever there may be any turbulence to speed up mixing. If no turbulent area is available, pour the ESS-13 into the water at various locations and it will mix and distribute by itself. This usually takes from six to ten hours. The water will be hazy white for several days to several weeks. When the water returns to normal color, the application is complete. The water can be used for irrigation if necessary before the two-week period has expired. Please mention as many details to your Seepage Control representative as you can about your particular project.

Maintain the water level for the 1 - 2 week application period, and then repeat the loss measurement. The ESS-13 will typically reduce the seepage rate 60-90%, usually in this initial time period. Whatever the initial seepage loss is, remember that the results will improve with time.

Keep the water in the pond after treatment. ESS-13 is designed for lakes and ponds that are not allowed to dry out. If water is kept in the pond, then one application is generally all that is necessary. Freezing conditions and daily irrigation cycles will not harm the effectiveness of an ESS-13 seal.

ESS-13 is an environmentally safe, non-toxic product. It is; however, a vegetable oil based product and can coat the gills of fish, causing suffocation. If there are any fish in the pond, they should be removed before application of ESS-13.
