    The Ground Gas Waterproofing System Works

    Full testing of Newton PAC System – remarkable results, Radon levels down from 5000 bqm to 100 bqm

    This patented system combines the Newton System 500 Cavity Drain waterproofing system, installed by our Newton Specialist Basement Contractor Network, with a positive pressure air delivery system, installed by Prestige Air Technology. The Newton Specialist Basement Contractor undertaking the work guarantees both the design and installation of the system and these can be further underwritten by an independent insurance scheme. Prestige Air provide integrity testing for the gas resistance of the installed membranes.

    The system includes a durable membrane Newton 508, that doubles as a drainage membrane and void former to allow for throughput of the air pressure created by the Air Curtain.

    Newton 508 membrane, and its associated jointing and sealing products, have third party testing accreditation for radon permeability.

    Installation & Testing

    The system can be installed in clearly defined stages depending upon the levels of ground gas identified or expected. The ability to upgrade the system dependent upon post-installation testing makes the PAC system highly cost effective – one that can be tailored to each individual circumstance

    Guarantees for Design and Installation

    “Having carried out a series of Radon monitoring it was established that we had levels up to 5000bqm within our basement of our home. In addition to this our basement was also damp. After failing to get levels down to acceptable levels by using a standard type retrospective sump, Prestige Air and Protectahome jointly installed the Newton PAC system for both Radon and waterproofing. We now enjoy a dry basement with levels of Radon less than 100bqm.”
