Newton 508

High-quality cavity drain waterproofing membrane, available in five variants.

Newton 508 is inert and non-polluting to drinking water, highly resistant to water, alkalis, saline solutions and organic acids, and not affected by minerals and hydro-carbons, and is resistant to bacteria, fungi and other small organisms. Newton 508R and 508 eco also exhibit high compressive loading stability.

Newton 508R is independently tested as an effective barrier to radon ground gases, with Newton 508R also tested as methane and carbon dioxide (CO₂) barriers, and these are the membranes used within the patented combined ground gas and waterproofing system, Newton PAC.

Consult manufacturer's literature for relevant preparation and surface protection.

Features and benefits:

• Used within Newton System 500, the internally applied waterproofing system that includes Newton drainage and pumping systems.
• Does not require extensive and damaging preparation to the wall surface.
• Quick installation.
• Provides vapour control, and when used with humidity control systems, is capable of delivering an environment to all levels within a Grade 3 environment to BS 8102: 2009.
• Resistant to rot, chemically aggressive groundwater, efflorescing salts and hydrocarbon contamination.
• Guaranteed against deterioration for 30 years and has a life expectancy of at least 100 years (has a service life that can be equal to the design life of the structure).

Suitable substrates:

- Walls:

• Concrete.
• Brick.
• Concrete block.
• ICF (with longer fixing plugs).

- Soffits:

• Concrete.
• Brick (arched or vaulted).

- Floors:

• Concrete rafts or slabs.
• Newton Fibran XPS 500-C closed-cell extruded polystyrene insulation.
