South Lodge Hotel & Spa, Horsham
Following the introduction of the new British Standard BS8102: 2009, it is common for a combined system to be installed to provide a ‘belt and braces’ approach to mitigate the risk of water ingress into basement areas. This is typically achieved with the installation of an externally applied waterproof system together with an internal cavity drain (water management system).
