Technical Statement
Product Description
Scope of use
The Allproof Perimeter Drain has been designed to specifically work in level threshold situations. The channel creates a 180mm x 200mm channel along the building line, the extra 30mm depth provided in the channel allows for a 1:200 screeded fall along the channel towards the outlet.
The adjustable bracket system with legs supported on the channel from the external side allows for a 12mm drip line along the joinery.
This system is designed to be customisable on site to create a tidy reveal following joinery lines around the building. Customised stainless steel grates can be manufactured to fit this product.

Product Criteria
Design requirements
The cleverly designed bracket and grate system takes up the varying reveal between joinery overhang and slab.
The grate selection accommodates for a variety of requirements including economy, performance (grate open area), safety (heelproof and slip rating) and customisation (aesthetics).
The grates come in a selection of materials including Glass Filed Nylon (GFN), Cast Iron and Stainless Steel that can be used to create consistency with other surface drainage in the same project (Allproof Polymer Concrete).
Installation requirements
When installing the system it is best to work from the centre out and to pre-plan the install understanding the lengths and cuts required.
To achieve an optimum aesthetic finish ensure that the channel runs parallel to joinery and not the building line so that grates do not have to be tapered to fit.
A full install guide is available from allproof.co.nz/drainage/level-threshold/perimeter-drain
Maintenance requirements
The grates have been designed to lock into place on the bracket with screws, these can easily be removed for maintenance purposes such as cleaning the channel to remove debris as required.
The stainless steel channel edge and grates (if applicable) can be maintained by following our SS maintenance guide, however this is purely for aesthetics and does not compromise the performance of the system.
