Sika helps waterproof hospital

Published by , Assistant Editor
World Cement,

Sika will supply a comprehensive waterproofing and concrete reinforcement system to a new district general hospital in Scotland.

The £270 million unit on the outskirts of Dumfries and Galloway will contain 350 beds as well as a new emergency care department, a combined theatre complex fro day surgery, endoscopy and surgical patients and consolidated ambulance care.

Specified by architects Ryder Architecture and the project’s contractors Laing O’Rourke, a total waterproof solution for the hospital’s basement and below ground floor will be provided using 18 000 m2 of SikaProof-A. This unique and easy-to-use waterproofing system contains a pre-applied sheet membrane facility, the surface of which is embossed with a grid pattern containing a sealant and is topped by a thin layer of fleece which forms a mechanical bond to the concrete when it dries. The grid pattern is also unique. It provides additional protection, due to the integrated sealant, which bonds tightly with the surface of the concrete, forming mini watertight compartments. Therefore, even if the membrane is damaged or pierced, moisture or pressurised water cannot spread between the membrane and the concrete structure as it is contained within the small damaged grid square.

Sika will also supply approximately 7000 m3 of its Watertight Concrete system for the project. Cost effective in comparison with membranes and other solutions, and able to deliver maximum usable area to the occupier, the product complies with BS 8102:2009 Type B Construction. It comes with a 15-year guarantee, providing peace of mind for the client, specifier and contractor. Sika’s waterproof membrane system was selected over competitors due to its high performance abilities in both water and gas resistance. The product range is complimented by the service offered by the operational team who provide excellent onsite advice adding to the overall performance not only as a product, but also a company.

Building work on the hospital – which will also include a heli-pad and 980 parking spaces – is due to be completed in 2017.
