RIW Hydrocoat is a cold-applied, fast-drying two-coat black bitumen waterproof coating designed primarily for demanding civil and infrastructure waterproofing applications. It dries to form a durable water and water vapour barrier on concrete, masonry and steel substrates, and is rapidly resistant to rain after application — making it practical in exposed site conditions where weather cannot always be managed. Unlike some bitumen coatings, Hydrocoat requires no stirring prior to use, simplifying application on large-scale projects. Minor damage to the cured membrane is self-healing, reducing maintenance requirements over the life of the structure. It is applied by brush, roller or spray at a coverage rate of 6m² per litre per coat, across two coats. Benefits Hydrocoat is suited to high volume applications across significant surface areas on infrastructure projects Fast drying and rain resistant soon after application No stirring required, making larger scale projects easier Self healing against minor damage Good to know Can be applied via brush roller or spray Suitable for masonry concrete and steel
