Subac is a high-strength, easy-to-mix, cement-based concrete and masonry patching compound designed specifically for placement in tidal zones and underwater applications. Subac will set and form a permanent bond to virtually any underwater surface. It is resistant to chemical attack, freezing and thawing, and can be used in all types of water.

Divers prefer Subac because, unlike other underwater cements, Subac does not separate or “smoke” in water, making it easy to apply under virtually any conditions, providing divers with maximum visibility to complete their work.
