DEVELOPERS SHOULD BE AWARE OF THE REQUIREMENT FOR A PATIO OR PAVED AREA TO SLOPE AWAY FROM THE PROPERTY, AS STATED IN PART H OF THE BUILDING REGULATIONS


fl ooding of the external area from spreading into the dwelling without compromising the aesthetic. This is especially pertinent in cases where level threshold access is to be implemented. Bi-fold doors are a common staple in the entrance design, however, the running track at the bottom leaves a slot for rainwater to collect when the doors are closed. Therefore, a correctly- specifi ed channel should be installed at the front of the running track to percolate the water out to a suitable outlet. On the subject of disposal, this element cannot be forgotten when installing


drainage channels. ‘Phantom drainage’ is a prevalent example of poor practice across threshold drainage, whereby the linear channels are connected to nothing. Without a suitable outlet there is nowhere for the water to drain and it will continue to collect until the channel overfl ows. This is why housebuilders must always determine where the collected surface water will be disposed of when implementing threshold channel drains.


FINAL THOUGHTS


The parameters discussed are a vital part of home design in ensuring building

thresholds are both attractive and functional parts of the property. When placing these considerations front of mind, it is equally important that housebuilders consult drainage experts to ensure the right solutions can be put in place. To this end, housebuilders and developers will be better equipped to implement effective drainage systems across their projects.
