Newton CDM 520 eco – 100% Recycled 20mm Cavity Drain Floor Membrane

The Newton CDM 520 eco is a high-performance, 100% recycled HDPE cavity drain floor membrane designed for use within the Newton CDM System—an internally applied Type C waterproofing solution incorporating drainage and pumping systems.

With a 20mm stud profile, Newton CDM 520 eco provides exceptional drainage capacity, making it ideal for areas with a high risk of severe water penetration. It is BBA-certified (No. 94/3010) and guaranteed against deterioration for 30 years, with a life expectancy equal to the building's design life (DIN 9001:2000).

Key Benefits

✔ High Drainage Capacity – 20mm stud profile handles significant water ingress.
✔ 100% Recycled HDPE – Eco-friendly, reducing environmental impact.
✔ Fast & Easy Installation – Optimized for rapid application.
✔ Durable & Chemically Resistant – Impervious to rot, alkalies, acids, efflorescence, and hydrocarbons.
✔ Vapour Control – Can help create a Grade 3 environment when used with humidity control systems.
✔ BS 8102:2022 Compliant – Meets UK waterproofing standards.
✔ Fire Resistance – Classified as Euroclass E for safety.
✔ Root & Bacteria Resistant – Unaffected by fungi and other microorganisms.

Typical Applications

🏗 Basement & Cellar Waterproofing – Used as a floor membrane within the Newton Type C CDM System.
🏠 New Build & Refurbishments – Suitable for both residential and commercial waterproofing projects.
🌊 Severe Water Exposure Areas – Provides a robust solution in structures vulnerable to high water ingress.

Compatible Substrates

✔ Newton Fibran XPS 500-C closed-cell extruded polystyrene insulation
