Clay 20kg

A high-quality clay product for sealing dams, ponds, and water features that need a reliable, natural waterproof barrier.

Cement Australia Clay is a natural sealing clay designed to create an effective waterproof barrier in dams, ponds, irrigation channels, and other water retention features. Applied correctly, it swells on contact with water to form a dense, impermeable layer that seals leaks and prevents water loss through the base and walls of water features and earthworks.

The 20kg bag size makes it practical for smaller sealing jobs, repairs to existing water features, and targeted applications where bulk clay would be impractical to handle or transport.
