Coral reef build with MakeMake Concrete Clay - safe for aquatic life.

Coral Reefs

Develop lifelike coral reefs and underwater formations using MakeMake ConcreteClay shaped over lightweight, water-compatible substrates. Sculpt intricate reef structures by hand or by using silicone molds for fine textures such as branching corals, plate formations, or porous surfaces. ConcreteClay offers excellent stability in aquatic environments, and when sealed with concrete paint (Colour Fix and Colour Pigments), it forms a durable, waterproof surface ideal for long-term submersion. Professional aquariums use this system to create modular reef elements that allow for easy installation, maintenance access, and stable coloration in underwater lighting.
