• Allproof Level threshold solutions are designed to allow level entry to the building and be fully compliant with New Zealand standards set out in Building Code E2, External Moisture
• Allproof supplies a range of E1-compliant pits and sumps that the Perimeter Drain can be connected to in order to complete the system

Design:

• The grate system takes up the varying reveal between joinery overhang and slab
• The grates come in a selection of materials including Glass Filed Polymer (GFP), Cast Iron and Stainless Steel that can be used to create consistency with other surface drainage in the same project (Allproof Polymer Concrete)
• The grate selection accommodates for a variety of requirements including economy, performance (grate open area), safety (heelproof and slip rating) and customisation (aesthetics).

Allproof floor level threshold drainage products have been designed for compliance with the scope outlined in building codes listed above and to be installed as per published installation guides.

For draining aggressive chemical substances, careful product selection is required, see product details for further information.

Concrete encasement for appropriate load class requirements is needed, see installation details for further information.

Designed for pedestrian traffic, specific custom design is required for load classes B and above.
