Newton PAC 500 Case Study – Museum of Jurassic Marine Life
The Museum of Jurassic Marine Life in Dorset opened to the public for the first time in October 2016. Home to over 2500 Jurassic fossils it uses a virtual aquarium so that visitors can experience what life was like underwater 150 million years ago.
The building was constructed in an area requiring radon protection. The protection measures required to provide this protection are described in the BRE Guidance Paper 211 (Radon Protection Measures for new Buildings) In the document Basic Radon Protection is described as providing a damp-proof membrane modified and extended to form a radon-proof gas-type barrier across the ground floor of the building and Full Radon Protection as comprising a radon-proof barrier across the ground floor supplemented by the provision of sub floor ventilation via a sump or sub floor void.
The water proofing requirements for the building as classified by BS8102 were to produce an Environmental Grade 3 dry environment and to do this a Type C internally applied system was selected. By installing the Newton PAC 500 Type C system both the waterproofing requirements and the radon protection were provided in one step. The central part of the system is a slim surface applied void former which is uniquely ventilated and the joints tracer gas tested during installation to provide a gas tight barrier which also waterproofs the structure.
