What results to expect
An affordable solution for sealing leaks in earth and clay-based dams.
Dam Stop Leak® Standard is a practical, cost-effective solution for helping seal leaks in existing earth and clay-based dams and ponds that have successfully held water in the past.
Made from a blend of polymers and mineral clay, it is easy to apply directly to the water surface without needing to empty your dam.
Suitable for stock watering dams, irrigation dams and farm ponds, Dam Stop Leak Standard helps reduce water loss by sealing leaks within the dam structure.
Key Features
- Cost-effective solution for leaking earth and clay-based dams.
- Easy application directly onto the water surface.
- No need to empty the dam before treatment.
- Suitable for dams that have previously held water.
- Available in 12kg and 18kg tubs.
Application Rate & Coverage
Apply at a rate of 80 g per square metre of water surface area.
- 12kg tub: Treats up to 150m².
- 18kg tub: Treats up to 225m².
For best results, ensure the water level is above the leak being treated. Apply when the water temperature is above 5°C, in light wind conditions, and when excessive aquatic vegetation or algae are not present.
Allow up to 30 days for the treatment to take full effect. If leakage reduces but does not stop, a further application may be required.
For customers seeking greater coverage per kilogram, see Dam Stop Leak Professional.
Important Information
Dam Stop Leak Standard is designed for earth and clay-based dams that have previously held water. It is not a substitute for correcting major construction faults, unsuitable soil conditions or significant structural defects, and it does not replace the need for an appropriate impermeable clay base.
This product is not specifically designed or tested for sealing leaks in concrete, metal or lined dams and tanks. Results will vary depending on the dam’s construction, soil conditions and the nature of the leak, and cannot be guaranteed.
Always read and follow the product label directions before use.

FAQ
Should I Turn Off My Pump During Application?
It’s recommended to turn off pumps or filters for at least 24 hours after application. Once the polymer settles at the bottom of your pond or dam, it will begin to seep into the pond walls. Make sure to check for any remaining material before reactivating the pumps.
Is Dam Stop Leak® Safe Around Fish?
Yes, Dam Stop Leak® is entirely safe for fish. It’s a non-toxic product. Keep a watchful eye on your fish until the product sinks to the bottom, as fish, especially koi, might mistake it for food when it’s on the water’s surface.
Can I Use Dam Stop Leak in Lined Ponds/Dams?
While Dam Stop Leak® is designed for use in clay or earth-based dams and water bodies, it can sometimes be effective in lined ponds or dams, but these cases are infrequent. In most situations, Dam Stop Leak® may not be the ideal solution for lined ponds or dams.
Will Dam Stop Leak™ Address Tree Root Damage to Walls and Rabbit Holes?
In clay or earth-based dams, Dam Stop Leak® is excellent for plugging dam walls with tree root damage and is effective with rabbit holes, though extra support may be needed for large rabbit holes, such as placing rubble or rocks before applying the product. For such cases, consider using Dam Stop Leak® Professional.
How Long Does It Take to Work?
On average, you should observe a reduction in water loss within seven days of application. If you don’t notice a significant change in water loss, additional treatment may be necessary.
How Safe Is Dam Stop Leak®?
Dam Stop Leak® is both non-toxic and environmentally friendly. Unlike other brands, our product contains no potassium, making it the safest solution available on the market.
