Newton PAC-500 System

Application

Can be installed to both new and existing projects, domestic and commercial to provides protection against:

  • Radon gas;
  • Methane gas;
  • Hydrocarbons and carbon dioxide;
  • Petroleum and diesel contaminated soils;
  • Water ingress.

Description

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 product 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.
