Description

The Newton PAC-500 System is a combined ‘Type C’ (BS 8102:2009) cavity drain waterproofing and ground gas mitigation system, developed by Newton Waterproofing Systems and Prestige Air Ltd. The addition of the PAC Positive Air Curtain to the System 500 waterproofing provides protection against water, gasses and hydrocarbon vapours from the ground within a single internally applied system. This system provides basement waterproofing across all environmental grades (Grade 1-3) in accordance with BS 8102:2009, as well a ground gas mitigation system that is integrity tested with tracer gas to confirm viability.

The Newton PAC-500 System consists of an 8 mm virgin HDPE void former/ in-line studded (cuspated) membrane applied internally to the floor and walls of the retained structure. A drainage conduit, Newton Basedrain, is installed in front of the wall membrane and below the floor membrane at the floor wall junction. A specially designed sump system, the Titan-Pro, is installed within the floor and receives two connections via sealed manifolds from the Basedrain System. All joints in the membrane and between membranes and the drainage and sump, are double sealed with butyl tapes. A conduit is installed behind the wall membrane at the top of the wall and again the membrane is double sealed to the conduit. A very low pressure, high volume fan introduces air behind the sealed membrane and pressurises the whole system.

An outlet pipe from the sump allows the pressured air to be removed to above external ground level. The continual flow of low-pressure air ensures that all ground gasses or hydrocarbon vapours meet a pressure air barrier as they attempt to enter the retained space. Ground gasses and hydrocarbon vapours that pass into the structure are received into the pressurised space created by the Positive Air Curtain and then safely pushed out of the property. Water entering the sump from the drainage channels is moved out of the structure with conventional pumps. The membrane system is protected by a screed to the floor and a wall lining system to the walls to provide the habitable space required.

The Newton PAC ‘Positive Air Curtain’ 500 System is a combined basement waterproofing and ground gas mitigation system which successfully controls both water and gas levels within below ground/ retaining structures. This patented system combines the Newton System 500 Cavity Drain waterproofing system, installed by the 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, 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.
