DamIt™ Dam Sealer is an advanced, non-toxic, polymer powder which can be used to seal leaking dams and ponds. The polymer is applied to a leaking dam or pond by scattering the powder across the surface of the water.

DamIt™ Dam Sealer allows you to:

• Fix your leaking earthen dam or pond
• Easily apply directly to the water surface
• No need to drain water or empty the dam
• No need for expensive earth moving equipment
• Fix it yourself as DamIt creates a permanent seal

DamIt™ Dam Sealer is insoluble and will form a long-term plug, in cracks and porous soils. The polymer stays active when wet and can withstand continuous wet/dry cycles to accommodate rising and falling water levels due to seasonal water level variations in the dam or pond.

DamIt™ Dam Sealer is a rapid, cost effective solution for sealing water leaks and does not require earthmoving equipment or the emptying of dams and ponds; allowing you to save valuable water and keep the dam or pond in use while repairs are undertaken.

DamIt™ Dam Sealer works on a wide range of soil types; from clays to sandy loams and in a wide range of water types; from clear, pure drinking water through to saline water with high levels of suspended clays typically found in rural stock dams.

DamIt™ Dam Sealer is applied over the surface of the dam/pond at a rate of 1 litre of DamIt™ Dam Sealer powder per 10 square meters (or 107 square feet) of dam.

If you have obvious signs of the leak (e.g. wet walls or water trickling out of ground), or you feel you know the general area causing the leak then DamIt™ Dam Sealer can be applied just to those areas of the dam/pond and a smaller amount of DamIt™ Dam Sealer will be required.

Allow 1 x 15ltr pail per 150m² (1600 sq ft) of surface area.

One application is normally sufficient to stop leaks permanently.

Converting Square feet to Square metres for estimating the amount of DamIt™ Dam Sealer Required.

If you don’t know your dam surface area in square meters; the coverage rate for DamIt™ Dam Sealer is 1L : 107ft² or a 15L bucket will be enough to treat an area of 1615ft².

If your dam is circular measure the distance across (diameter) and use the following formula to calculate area – 0.785 x Diameter x Diameter. Eg distance across dam is 10 meters, area is 0.785 x 10 x 10 = 78.5m².

We’re always happy to assist in calculating the amount required. If you aren’t sure or have a difficult shape please use the Contact Us page and send details of your project.

Damit is not suitable for the following applications

• Ponds made from fibreglass, plastic, rock or concrete – Damit is designed for earthen ponds only
• Ponds with rubber or PE liners – Damit may work if you have a layer of clay/silt over the liner, but ideally Damit needs to be able to freely percolate into the soil
• Small and/or shallow ponds – Damit expands significantly after application
• Streams, water features or moving water – Damit is designed for still ponds and dams
• Heavily planted ornamental ponds with reeds and grasses – Damit will attach to vegetation
• Fish or aquaculture ponds – Damit is not toxic to fish but care should be taken to apply Damit in stages where fish are present to minimise any impact

Note: Damit will reduce soil porosity but it is not a cure-all and we cannot guarantee use of this product will stop your leaks

DamIt™ Dam Sealer becomes very slippery when wet. The use of gloves is suggested when hand spreading to keep DamIt™ Dam Sealer dry until ready for use.

The container must be well sealed in high humidity to stop absorption of moisture, by the polymer, prior to use.

Discard any polymer powder which has been wet, forms lumps, or a slippery gel consistency.
