Efflock, Maroubra, NSW

Efflock is an Australian-owned building product company specialising in advanced water repellent additives designed to protect concrete, brick, and masonry from damp, efflorescence, and moisture damage. Since 2012, Efflock has provided high-performance hydrophobic solutions used across residential, commercial, tiling, and waterproofing applications. Unlike surface sealers, Efflock works within cement-based materials to reduce water absorption while allowing natural vapour transmission, improving durability and long-term structural protection. The product is widely used in screeds, tile adhesives, grout, brick mortar, stone masonry, renders, and precast concrete systems. VOC-free and environmentally responsible, Efflock delivers permanent protection against salt attack, rising damp, and water-related deterioration. Based in Sydney, Efflock supplies trusted waterproofing solutions through authorised distributors across Australia.
