MARINO, SA

This beachfront home in South Australia was plagues with ongoing water ingress and mould to the lower level for over five years, with the owner engaging multiple professionals to solve the issues, with no success. The room was constructed with zero boundary to two adjoining properties which made for a challenging repair.

Project Description

The structure is built with zero-boundary to two of the neighbours’ properties, meaning external excavation and repair was not a viable repair option without partly demolishing the neighbours’ home as well.  As you can see in the photos, water had entered continuously for several years causing complete soaking of the internal floors and walls, and extensive rusting of the metal framework.  The owner was at the point of considering demolishing and rebuilding the structure when he discovered Dryspace Solutions and their Cavity Drain solution.  After a short phone consultation, it was clear a solution was possible.    

After reviewing years of investigation reports, we were confident a repair was possible without excavation, so our Technical Manager flew to Adelaide to conduct a site inspection and was able to provide a detailed repair solution using a cavity drain system, with a genuine warranty, and without any external excavation! 

Design Solution

For health and safety all internal linings to the walls and floors were removed to allow the Newton System 500 Cavity Drain System be applied. The owner engaged his own builder who completed all preparation works in line with our recommendations.  This enabled a smooth handover to Dryspace technicians who completed the full installation within one week, ready for reinstatement works to be undertaken. 

The room had a ceiling height over 3m, which allowed the installation of a ‘Built-Up-Floor’ design using an insulating foam spacer.  This system allows the floors to accommodate the perimeter drainage conduit without costly and time-consuming concrete cutting and jackhammering for setting in the perimeter drainage channel. 

Works included the installation of Newton System 500 to the full-height internal walls using Newton Multiplugs, detailing of all penetrations, and installation of the membrane over the ‘built-up’ floors. The Newton Basedrain system was installed to the perimeters of the room with new drainage connections to divert any water out of the property and to the external stormwater connections. 

Reinstatement works are currently underway, being completed by the completed by the Builder.  For the first time in over five years the owner will again be able to utilise the space.
