Newton 809-DPC

Application

  • Horizontal, vertical and stepped damp-proof course.
  • As part of the Newtonite Damp Proofing System when used in conjunction with Newton System 800 damp proofing membranes.
  • As part of the Newton CDM Waterproofing System when used in conjunction with Newton System 500 waterproofing membranes.

Description

A high performance damp proof course that will not extrude under extreme load, and will not affect the ability of a well designed and built wall to sustain and transmit compression. Compatible with all common building materials and suitable for all designs for different damp proof courses.


Features and benefits:

  • Extremely tough and durable.
  • Will not deform or extrude under high compressive loads.
  • A complete system includes cloaks and accessories.
  • Flexible at low temperatures.
  • Resistant to and shrinkage.
  • Effective barrier to water and water vapour.
  • Bond of Newton 809-DPC is greater than the bond between mortar and brick.
  • CE marked.


Suitable substrates:

  • Brick and block;
  • Stone;
  • Concrete;
  • High load insulated wall courses such as Marmox Thermoblock and Foamglas Perinsul.
