This upgrade has been Architecturally designed by renowned Wellington based architects Alistair Cox Architects to be a habitable space with contemporary and high end finishes - so water ingress of any kind was not acceptable. Therefore Newton Specialist Contractor Riteway Waterproofing were bought in to waterproof the lower level and basement area of this sloping site.

This is a heritage building in an area of high earthquake risk. Also there is no ability to access or “dig out” the external side of the structure so all waterproofing had to occur internally.

After considering all of the above - Newton System 500 Cavity Drain Membrane (CDM) was recommended, designed and installed.

The Newton CDM System provided the internal Type C waterproofing solution, and the most failsafe and reliable form of waterproofing protection. This maintainable and effective system combines CODEMARK approved cavity drain membrane and drainage channels that encompass the space to create a solution that depressurises ingressing water before safely managing and removing it from the structure. As this property is on a sloping site then were able to utilise natural drainage to remove the water from property.

The selection of the Newton System 500 stems from its compatibility with historic buildings. Its application is gentle on the structure, with the added benefits of flexibility and reversibility.
