The Newton PAC 500 (Positive Air Curtain) System is a combined basement waterproofing and ground gas mitigation system which successfully controls both water and gas levels within below ground / retaining structures. It can be installed to both new and existing projects, domestic and commercial.

The patented system combines the Newton System 500 cavity drain waterproofing system, installed by 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 provides integrity testing for the gas resistance of the installed membranes.

Provides protection against

  • Radon 

  • Methane 

  • Hydrocarbons and carbon dioxide

  • Petroleum and diesel contaminated soils

  • Water ingress

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

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.
