GREY water drainage is important for water management. Drainage equipment must comply with certain principles to ensure proper drainage before treatment.

Our FRANCEAUX flooring product range meets these principles: to ensure a rapid evacuation of GREY water and to prevent the access to the premises of stale air coming from sewers.

Our drainage systems are easy to inspect and guarantee maximum hygiene for the most diverse applications. Our siphons and AVALOIRS are all made of stainless steel or cast iron, giving the products better properties and increased durability.


Our tiled manholes, made of galvanized steel, stainless steel or aluminium installed inside or outside the buildings, provide secure access to crawl spaces, basements and technical ducts. It is the ideal aesthetic solution to preserve the continuity of the tiled or paved aspect of your floor while preventing the rise of bad smells.
