AWMS: Essential Non-Combustible Drainage Solutions for High-Rise Construction

2 mins

ALUMASC WATER MANAGEMENT SOLUTIONS (AWMS) is the UK’s leading manufacturer of integrated non-combustible rainwater and drainage systems encompassing the entire building envelope.

Its drainage solutions assist with compliance to the Building Safety Act 2022, specifically BS EN8579:2020—A Guide to the design of Balconies and Terraces, which emphasises the importance of fire safety in the drainage design of balconies and terraces. 

The AWMS system incorporates Harmer Aluminium Roof Outlets1 featuring new extended spigots connecting directly to a welded spigot on Alumasc’s Aluminium Downpipes, eliminating any potential incompatibility.

Both products have a well-established track record of use in the high-rise building sector. The Harmer Aluminium Roof Outlet range is suitable for all types of flat roof application, including balconies and terraces. Alumasc Aluminium Downpipes2 have a
history of specification on many high-rise projects, and are available in a range of popular profiles.

Harmer Roof Outlets and Aluminium Downpipes are both BBA-approved powder coated, making them A2-s1, d0 fire-rated, ensuring conformity to the new regulations in most applications. To complete the AWMS fire-resistant offer, the Harmer Modulock Pedestal System3 offers a range of non-combustible raised pedestals designed to create level flooring in any building application where sloped, stepped, or irregular surfaces present a challenge. They are manufactured from mild steel with a highly durable zinc nickel, corrosion-resistant finish, making them A1 fire-rated. This complete package of non-combustible outlets, downpipes and pedestals is 100 per cent recyclable.
