Type C

(Drained Protection)

Type C waterproofing protection manages water that penetrates the external shell of a structure, by collecting it in a cavity formed between the external wall and an internal lining/wall, directing it to a suitable discharge point, e.g. drains or a sump for removal by gravity drainage or mechanical pumping.

BS: 8102:2022 defines Type C waterproofing as “drained protection” where water leaking through the structure is accepted into voids and air spaces, created by cavity drain membranes that are strategically placed to the inside of the structure, depressurizing the incoming water and safely removing it from the property.

This maintainable basement waterproofing solution is ideal for both new-build basements and refurbishment projects. The system comprises of CodeMark and BBA approved cavity drain membranes, drainage conduits, sump chambers, pumps, and associated control and telemetry systems.

Consideration to compliance with the New Zealand Building Codes, may include performance clauses such as:

  • Clause B2 Durability: B2.3.1 (a), B 2.3.2 (a)

  • Clause E2 External Moisture: E2.3.3, E2.3.5, E2.3.7

  • Clause F2 Hazardous Building Materials: F2.3.1

  • The Membranes

    Enhanced Strength and Durability: Heavier and stronger than standard 8mm membranes, CDM 508R provides robust protection with a 30-year guarantee, CodeMark and BBA Certification

    Dual Functionality: Serves as both a waterproofing membrane and a gas barrier, effectively protecting against radon, methane, CO2, and hydrocarbons.

    Chemical and Biological Resistance: Inert and non-polluting, CDM 508R resists water, alkalines, saline solutions, organic acids, minerals, hydrocarbons, bacteria, fungi, and small organisms.

    Comprehensive System Integration: Designed for use with the Newton CDM System, including drainage and pumping systems, ensuring a complete waterproofing and gas protection solution for earth-retained walls, vaulted soffits, and floors.

    Tested and Certified: Independently tested for high compressive loading stability and effective ground gas barrier performance, making it ideal for demanding environments and integrated protection with the Newton PAC-500 system.

  • The BaseDrainage

    Efficient Water Management: Designed to effectively collect and discharge water ingress within the Newton CDM System, preventing water accumulation and ensuring a dry basement environment.

    Comprehensive Integration: Works seamlessly with CDM XPS-500C insulation boards, utilizing the 18mm holes for optimal water entry from beneath and within the spacer zone.

    Enhanced Drainage Performance: The strategically placed holes on both sides and the top surface of the profiles facilitate efficient water flow into the drainage channels, improving overall system performance.

    Reliable and Durable: As part of the Newton CDM System, CDM BaseDrain and FloorDrain are built to provide long-lasting and robust drainage solutions, ensuring consistent performance and protection against water ingress.

    Supports Safe Water Discharge: Channels collected water to a Newton Basement Pumping System or safe drainage, providing a reliable solution for managing water ingress in below-ground structures.

  • The BaseBoard

    Reliable Water Management: Effectively captures and redirects water at the critical wall/floor junction, reducing the risk of internal water ingress.

    Ease of Installation: Designed for a fast and secure fit using clip-in hangers and jointing pieces, saving time on-site and minimising disruption.

    Integrated Waterproofing Solution: Works seamlessly with the Newton CDM System, including membranes and adhesives, for a comprehensive, professional-grade waterproofing setup.

    Above-slab drainage conduit that is designed to capture water that is entering properties via the wall/floor junction for removal to an appropriate drainage medium.

  • The Pumping Systems

    Optimised Integration: Specifically designed for use with the Newton CDM System, ensuring seamless compatibility and performance.

    Adjustable Installation: The adjustable neck allows for precise installation at a fixed height relative to the slab, ensuring consistent connections to the Newton drainage system and pump discharge line.

    Flexible Pump Configuration: Supports single and twin pumps, as well as twin pumps with twin discharge lines, offering scalable options for enhanced pump efficiency.

    Versatile Connection Options: Unique sump shape and multiple inlet and outlet positions allow for flexible connections to side walls or corners, providing adaptability for various installation scenarios.

    Enhanced Water Management: As part of the comprehensive Newton CDM System, Pump Systems ensure efficient water discharge, maintaining a dry and protected basement environment.

  • The Back up

    Reliable Power Backup: Converts battery-stored DC energy into 230 VAC power, ensuring uninterrupted operation of Newton Pumping Systems during power outages.

    Tailored Solutions: Available in three sizes, providing customised power backup options to match the specific needs of different pumping systems.

    Advanced Control and Monitoring: Includes a range of ancillary components for enhanced system control, telemetry and cloud based, offering comprehensive management and peace of mind.
