Inverted Roofs For Concrete Slabs
Inverted/Wet Insulated Concrete Roof Application. Important – this is the most basic inverted system and does not include the bidm cloth or drainage system.
As noted, we can customize the complete system to suit the architects and clients requirements as needed.
Once the torchon is completed with the protective aluminium coating, this system is installed.
Advantages – it protects the waterproofing layer (the buried system does not require 3-yearly service intervals), insulates the building structure very well and is extremely pleasing to the eye.
Process Concrete slab applications
Any and all concrete slabs. As noted we do not do the actual slab and building up of the concrete slab that would be the builders/developers scope of works.
