For this project, Aaron FM’s engineering team delivered a complete roof waterproofing system including:

• Removal of existing chippings to leave a chip-free surface and release and re-seal all blisters
• Making good any defects in the roof covering and removing all superfluous materials, dust, and debris to leave the roof in a clean and dry condition
• Supply and application of SPV High Bond Primer to the existing waterproofing
• Supply and installation of 15mm thick bitumen-impregnated recovery board bonded in bitumen to the primed surface
• Supply and torch application of SPV 3mm Elastomeric Underlay
• Supply and torch application of SPV 4mm Elastomeric Mineral Cap Sheet
• Inspection and maintenance of upstand details with primer application
• Application of new waterproofing to upstand details comprising SPV 3mm Elastomeric Underlay and 4mm Elastomeric Mineral Cap Sheet
• Removal and disposal of lead, with the new felt system encapsulating the parapet detail

The works were completed within the 25-day programme, delivering a high-performance waterproofing system that will protect the building for years to come.
