Thousands of UK driveways are at risk of sustained drainage issues due to the under-specification of drainage channels with appropriate load-bearing capacity.
The warning, from ACO Technologies, one of the UK’s leading drainage manufacturers, is the result of increasing concerns that low load-bearing A 15 drainage channels are being incorrectly used for trafficked applications.
Phil Windus of ACO Technologies said "There is a concerning trend within the construction industry of low load-bearing capacity drainage channels, such as those designed for use on pedestrian footpaths, being used on driveway entrances, despite not having the load-bearing capacity to cope with vehicle traffic".
The issue likely stems from a lack of training amongst subcontractors and groundworkers about the designated purposes of drainage channels and their composite materials. Mr Windus continues "Both manufacturers and merchants have a duty to ensure the correct products are used and specified by housebuilders, driveway specialists, subcontractors and groundworkers. However, I would also encourage any contractor who is unsure as to what is the most appropriate solution, to have the confidence to speak directly with their merchant or the manufacturer to clarify what may or may not be suitable.”
