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
drainage solution 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.
