Ensuring that products are fit for purpose is essential when selecting a drainage product for any membrane roof or balcony installation.

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 New Zealand-made membrane clamp ring drains and accessories for more than 30 years. In fact, the company began its evolution as a manufacturer of drainage products when it started supplying waterproofing products in the 1980s.

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 1990s. Since this time, it has significantly expanded its manufacturing capability and product range at its manufacturing base on Auckland’s North Shore.

This has enabled the company to offer an extensive range of membrane roof and balcony drainage products to suit every project, providing specifiers with options when selecting the best product for any project.

Working with industry, and using its manufacturing capability, Allproof is able to offer an end-to-end solution for specifiers.

Allproof designs and manufactures prototypes and tooling, injection moulds, and CNC machines and fabricates its range of waterproofing membrane drainage products.

The company uses a nationwide network of distribution outlets and salespeople, and quality is assured through independent certification of its manufacturing and products.

Throughout 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 use 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,
      and ceiling or soffit cavity space available for downpipe,

• Membrane type: thickness, adhesion method (glue or heat),

• Flow rate: catchment area, open or covered, and

• 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.
