Dam Stop Leak Professional is a potassium-free polymer sealant that creates a permanent plug in any leaks or cracks of an earth or clay-based dam. No need to drain the pond or dam, simply apply the required amount directly into the water over the affected area, or treat the entire waterbody, to achieve long lasting results.
Because it’s 100% polymer, Dam Stop Leak Professional means less is more. Less product to fix a larger area, making this product perfect for larger dams or bodies of water.
Dam Stop Leak Professional is environmentally safe and non-toxic. It is safe for use around fish, other aquatic animals, plants, wildlife, pets, and livestock.
