Industry Leading Roof & Balcony Drainage Systems

When selecting a drainage product for any membrane roof or balcony installation, you need to ensure that the product is fit for purpose. When specifying the best drain for any waterproofing membrane installation, correct product selection needs to consider the type of membrane, the location and detail of the install, the required flow rate and the project budget.

Allproof has been supplying NZ-made membrane clamp ring drains and accessories for over 30 years. In fact, Allproof began its evolution as a manufacturer of drainage products when it started supplying waterproofing products in the 1980’s. Identifying the importance of specialist drainage products for waterproof membrane installations, Allproof began developing and manufacturing its extensive range of roof and balcony drains in the 1990’s. Since this time, Allproof has significantly expanded its manufacturing capability and product range at its manufacturing base on Auckland’s North Shore. This has enabled Allproof to offer an extensive range of membrane roof and balcony drainage products to suit every project, this provides specifiers with options when selecting the best product for any project.

Working with industry, and utilising its manufacturing capability Allproof is able to offer an end to end solution for specifiers. Allproof designs, manufactures prototypes and tooling, injection moulds, CNC machines and fabricates its range of waterproofing membrane drainage products. Allproof utilises a nationwide network of distribution outlets and sales people and quality is assured through independent certification of its manufacturing and products.

Through its history, Allproof’s solution focused approach has led to the development and introduction to the New Zealand market of products such as injection-moulded plastics for heat applied waterproofing membranes, integral drainage overflow systems and the Allthrough balcony drainage system. These products all utilise various fit-for-purpose material components that Allproof manufactures including Plastic, Stainless steel and bronze.

Each project is different and factors relating to the specific installation details can have an impact on the selection of a roof outlet for a particular project. When selecting from Allproof’s extensive range of roof or balcony membrane drainage products issues to consider include:

Spatial: width of gutter, proximity of downpipe to wall or corner, ceiling or soffit cavity space available for downpipe

Membrane Type: thickness, adhesion method (glue or heat application)

Flow rate: Catchment area, open or covered

Environmental: Coastal or sea spray zone, geothermal, extreme temperatures

Considering these details, Allproof’s range has developed to include small or larger diameter drain bodies, side outlet and scupper options, dome or flat grate options, membrane, tile or raised deck finishes, overflows and balcony Allthrough drains. All these products are independently flow rate tested by a NATA certified laboratory for piece of mind. Combined with years of infield service, Allproof’s product warranty and after sales service, a specifier or installer can be confident that the products are fit for purpose and meet the needs of the application.
