ACO ThresholdDrain
Description

ThresholdDrain is suitable for use on balconies, general outdoor patios and entertainment areas. It allows the finished areas outside a building to be made level with the floor levels inside the building.

This dramatically reduces the risk of surface water transgressing the entrance threshold and collects runoff from doors and windows during storms. Its unique cantilever bracketing system is anchored between successive concrete pours beneath exposed slabs, tiles or pavers.

ThresholdDrain is intended to be installed adjacent to entrance doors and complies with the prescribed requirements of Clause E2 External Moisture of the New Zealand Building Code. The system can be adapted to different drainage trench widths.

ThresholdDrain can accommodate four different grate pattern designs complying with Clause 9 — AS1428.2, Access and Mobility, ensuring safe passage of walking canes and wheelchairs. Three high heel safe grate options are also offered including the widely specifed Stainless Heelsafe Anti-Slip grate.

In-Service History

Continental Cars’ Ferrari dealership is a flagship store for the brand.

Strict corporate guidelines dictated many of the design decisions, however ACO was able to provide a solution for New Zealand specific level threshold drainage. The fit-out of the interior featured the signature Ferrari red, and liberal amounts of stainless steel.

Architects sought to link inside and out by using the Stainless Steel 5 star Heelsafe Anti-Slip grate at level thresholds. A combination of KlassikDrain KS100 for vehicle entrances and E2 compliant Cantilever ThresholdDrain for pedestrian entrances allowed a code-compliant solution. Matching grates across both products tied the project together with the aesthetic demanded by Ferrari.
