Seal Ponds – Pure Blanket Methods
Clear the area of any surface rocks and vegetation, and remove the top four to six inches of soil from the bed of the pond, lake, sewage lagoon, etc. For best results, smooth the area with a roll or a drag plank. Cover the area you want to seal with the predetermined thickness of our granular Texas Sodium Bentonite. A mechanical dry fertilizer spreader with controlled distribution is a good application device as well as a front-end loader.
For best results get a solid cover over the area you want to seal. Avoid leaving bare spots that may result in seepage. Applying a uniform layer during application assures complete coverage and a successful seal. After spreading the sodium bentonite, carefully replace the top four to six inches of soil removed earlier. Avoid disturbing the bentonite liner. Then tamp the area to compact the surface. Begin filling with water (gentle flow) if possible. The full saturation of this product may take approximately 60 to 90 days.
In all sodium bentonite application methods, the swelling of the particles stops the leak. Sodium bentonite will not stop the leak immediately. Some seepage is expected for up to 60-90 days after the sodium bentonite is applied. Generally, the leak is stopped or slowed within 45 days, because of underlying circumstances such as rocks, roots, and underground springs, some ponds require more sodium bentonite than the recommended amount. Some ponds, due to poor site selection or improper design and poor construction may never seal completely. Therefore, we cannot guarantee this product.
Keep in mind these two things when sealing a pond or stock tank.
Using the recommended amount of sodium bentonite per square foot is essential based on your soil type and the size of the area you are trying to cover.
An even application ensures. an impenetrable bentonite liner.
