  • Sustainable Construction Material: Manufactured from verified recycled HDPE, reducing reliance on virgin polymers while maintaining full Type C waterproofing performance with the our 508 eco.
  • Chemical, Biological & Root Resistance: Inert, rot‑proof, and resistant to fungal and bacterial attack, root penetration, and a wide range of chemicals.
  • Integrated System Compatibility & Long Service Life: Designed for use with the Newton CDM System for walls, floors, and vaulted soffits, supplied with a 30‑year product warranty and a service life aligned with the building’s design life.

Championing Circular Sustainability – 508 eco

Made from 100% recycled HDPE, the 508 eco reduces our use of virgin plastic without compromising on performance.

This environmental benefit is amplified by our industry-leading Recycling Service, which collects used HDPE membranes, off‑cuts, and plastic packaging directly from site. Rather than going to landfill, materials are recycled back into production, reducing waste and creating new products like 508 eco.

Designed for use in the CDM System, 508 eco creates an 8mm drainage void to safely manage water ingress behind internal finishes. Independently tested to DIN EN 1928, the membrane is fully waterproof and integrates with our drainage and pumping components to form a complete ‘Type C’ internal waterproofing system for retaining walls, vaulted soffits and floors.

Inert and rot-proof, 508 eco resists roots, chemicals, and biological attack to deliver long-term performance. This is supported by a 30‑year product warranty and a service life suitable for the design life of the structure.

Our 508 eco is the trusted, sustainable choice for both new‑build and refurbishment waterproofing projects.

    1</sup< EN ISO 25619-1 test data obtained from Newton 508R. Newton 508 eco is manufactured to the same design and dimensions using the same production process and is expected to provide equivalent performance.

    *Screeds placed above non-bonded materials such as sheet HDPE membranes are categorised as floating screeds within BS 8204 & BS 13318 and require a section thickness of 65 mm or more for sand and cement, or 35–40 mm for proprietary liquid screeds. Check load capability with proprietary liquid screed supplier. Further information is included within the Protection Of The Membrane and Compressive Load sections on page 4.

    The above data is based on manufacturer-supplied information and, even where stated as tested to recognised standards, should be treated as indicative. Site conditions, system design, installation quality and protection of the membrane may affect installed performance.

    British Standard 8102:2022

    British Standard 8102:2022

    The British Standard 8102:2022 Code of Practice for Protection of Below Ground Structures Against Water Ingress is the main design guide for structural waterproofing in the UK.

    The Newton CDM System is a maintainable system, so it complies with BS 8102 requirements. The standard also specifies that: “a waterproofing specialist should be included as part of the design team so that an integrated waterproofing is created”

    Therefore, it is our recommendation that the Newton CDM System is installed by a Newton Specialist Contractor (NSBC).
