Specifying Balcony Drainage Systems in Multi-Residential Design
Published

Balcony design, and in particular drainage systems are a critical design consideration for multi-residential developments.
A common error in specifying linear drains on balconies is to indicate a standard linear drain for threshold areas where a specific Threshold drain is required. If this error is only discovered at a later stage of the building process, it can lead to costing problems for the whole building project. At worst the building project will be delayed because of the wrong drainage specified, which can lead to costly variations.
Threshold drainage is an ideal solution for protection against water from the outside while still providing a continuous accessible path between the inside and outside. A threshold drain consists of an external linear grate which sits externally beside the door track. An integrated, concealed, sub-sill collects water and condensation around the doorway and conveys it to the external drainage system. As the door systems drain the water to the outside of the building at the sill, the linear drain can be positioned on the outside of the door to capture that water while not impacting the designed water performance of the door system.
Popular placements for standard linear drains is at the outer edge or across a balcony in cases of extreme water exposure or for design considerations.
