Developed for balconies, general outdoor decks and entertainment areas, ThresholdDrain stops rainwater transgressing past the entrance threshold of buildings and also collects runoff from doors during storms.  Its cantilever bracketing system is designed to be 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 the New Zealand Building Code for Surface Water – NZBC E2.  Furthermore, the system can be adapted to suit any width of drainage trench.

ThresholdDrain can accommodate seven grate types comprising five different grate pattern designs complying with Clause 9 – AS1428.2: Access and Mobility, which ensures safe passage of walking canes and wheelchairs.  High-heel-safe grate options are also offered, including the widely specified Heelguard grate.
