Popular Sealing Methods
Bentonite Clay
Bentonite, often called “The Miracle Clay” is a pure, organic, natural product mined and produced in South Africa that has a wide range of uses, however here we will focus on using it mainly for the sealing of dams, ponds, streams, and other waterways.
Mineral Filled Polymer Composites
We utilise advanced mineral-filled polymer composites to create highly durable and flexible sealing solutions for dams and ponds. This innovative material forms a seamless, long-lasting barrier that adapts to ground movement while preventing leaks and water loss. It’s a modern, environmentally conscious alternative to traditional clay or cement sealing—engineered for strength, longevity, and performance.
Thin Rubber Linings
Dam Sealers offers thin rubber linings as an effective solution for dam sealing. These linings provide a flexible, watertight barrier that conforms to the contours of your dam, preventing leaks and water loss. Lightweight yet durable, they are quick to install and ideal for both small farm dams and larger water retention projects.
Flexible Cemintatious Linings
We use flexible cementitious linings to provide a durable, watertight seal for dams and ponds. This material combines the strength of cement with flexibility, allowing it to adapt to ground movements without cracking. It offers a long-lasting, low-maintenance solution for reliable water retention on farms, estates, and larger water projects.

Earth Dam Sealing & Construction Frequently Asked Questions
The cost of our dams is influenced by various factors beyond just size. The topography of your land, selected upgrades, the project’s location, the soil type, and the need for tree clearing can all affect the final price.
The ideal location for your pond or dam is usually in valleys or low-lying areas of your property. Installing atop a hill is not advisable. Additionally, ponds should not be placed near lagoons or septic systems, too close to public roads, neighbours, or within easements.
While we do not directly supply fish or wildlife, we have trusted partners who can assist you in populating your pond or dam.
Expect your dam to naturally fill up over approximately one year, depending on local weather patterns and water sources.
Our ponds and dams fill naturally, relying on sources like springs, runoff water from creeks, roads, slopes, roofs, and rainfall to reach full capacity.
We recommend a depth of 2 – 4 meters for a 4000 sqm pond to ensure a healthy aquatic environment and stability.
Permits are typically required for pond and dam construction. The property owner will need to contact the relevant authorities.
