    [siteorigin_widget class=”SiteOrigin_Widget_Slider_Widget”][/siteorigin_widget]

    Newton provide waterproofing products for all three types of waterproofing

    1. Type A System – Barrier Protection, attempts to hold water back by applying a barrier (tanking) to the walls and floors of the basement or

    2. Type B System – Integral Protection, the structure itself is constructed to be integrally waterproof and the primary resistance against water ingress or

    3. Type C System – Drained Protection, internal cavity drain system (drained cavity) which receives, depressurizes and then discharges water ingress.

    Our Recommendations for Structural Waterproofing

    When tasked to waterproof retaining structures in accordance with the New Zealand Standard, professional waterproofing designers should consider using more than one type of waterproofing to provide enhanced protection of the structure and achieve the necessary internal environment. Combination strategies provide increased waterproofing protection to the structure where the risk of leaking is high and the consequences of leaking are unacceptable.

    Whichever combination of waterproofing is chosen, to achieve a completely dry Grade 3 internal environment we would always recommend that one of the forms of waterproofing is a Type C internal cavity drain membrane system. A ‘maintainable waterproofing system’ where products are accessible and can be reversed if necessary. The choice of the other system is largely dictated by the type of structure.

    Newton System 500 is a Type C cavity drain membrane system that comprises wall and floor membranes, drainage as well as mechanical pumping systems, if required.

    Newton provide waterproofing products for all three types of waterproofing:

    Type B (structurally integral) protection – Newton System 300

    Type C (drained) protection – Newton System 500

    Newton 103-S used as a hard-wearing durable membrane for use in a car park specification. This can be used on a concrete deck which could be situated above a dry internal environment.

    “As a long-standing Newton customer, we’re always being kept up to date and supported with the latest product developments, like Newton 109-LM, and getting the right training for our contractors. The liquid rubber is something we’ve used before and it’s always really quick and easy to apply, regardless of how it’s applied or what it’s being used for. Using the drainage membrane alongside was good for this job too, as it meant the finishes could be put back in quickly. Gunwharf Quays was back in use swiftly.”
