Free Lime Inspections made easy with forward thinking New Yellow Channel

elta Membrane Systems Limited – today launched an entirely new product line designed to make channel inspections easier. With Delta’s new yellow channel ‘free lime’ can easily be identified and then treated. Free lime is generally white in appearance and can build up to a solid mass, with Delta’s new yellow channel this can easily be visualised during the inspection and appropriate action taken. Delta’s new yellow channel is complemented by a range of accessories such as Straight Connectors, 110mm outlets, Corner Pieces, T Pieces and Drainage Channel End Caps. What is a Cavity Drain System? A Cavity Drain Membrane System is a Type C Waterproofing solution. The concept of a Drained Cavity System is to collect and manage any groundwater which breaches the integrity of a structure by managing, collecting and discharging such free water via a suitable evacuation point such as a Delta Package Pump Station. What is a channel? Delta Channel is a water collection conduit designed to control water ingress in below ground applications and to make the system easily maintainable. What is Free Lime? With new concrete structures, there is a risk of excess free lime leaching out from the concrete as groundwater passes through the new structure, through joints, cracks and dry pack, in the form of calcium hydroxide (free lime). If untreated, this free lime can enter a cavity drainage system which can impede the flow of water and cause sump pump failure. BS8102:2009 The British Standard for waterproofing BS8102:2009 recognises the requirement of a Type C Waterproofing System or Cavity Drain Membrane System to be designed to be maintainable. The use of inspection ports within the drainage element of a basement waterproofing design is key for maintenance or the ability to carry out periodic inspection.
