Newton DampSafe 809 HP DPC – 300mm x 20m

High Performance Physical Damp Proof Course. Newton DampSafe 809 HP DPC is a high-performance, radon-rated DPC which will not extrude under load, up to the point of the compressive failure of the wall. It will also not adversely affect the ability of a properly designed and built wall to sustain and transmit compression. Available in 20-metre rolls and in eight widths from 100 to 900 mm – this option is a 300mm x 20m roll. 

DampSafe 809-HP DPC is compatible with all commonly used building materials and is suitable for horizontal, vertical and stepped damp proof courses, including cavity trays, in cavity or solid masonry walls, and is also suitable for extending the floor membrane through internal and spine walls within the Newton CDM System for cavity drain waterproofing.

Key Benefits: 

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

Typical Applications: 

• Horizontal, vertical and stepped damp-proof courses 
• As part of the Newtonite Damp Proofing System when used in conjunction with Newtonite System damp proofing membranes 
• As part of the Newton CDM Waterproofing System when used in conjunction with Newton’s cavity drain waterproofing membranes

Suitable Substrate: 

• Brick & Block 
• Stone Concrete
• High load insulated wall courses such as Marmox Thermoblock and Foamglas Perinsul
