How a seamless Liquid 10 waterproofing system made a flat roof in Putney fully watertight — edges, upstands, outlets and every junction included.
The flat roof at this Putney property needed a new waterproofing layer across all of its areas. Like most flat roofs, the weak points were the details — perimeter edges, upstands, abutments and outlets — so any new system had to seal those as thoroughly as the open roof surface. Access was only possible from the side of the property, so safe access had to be set up before any work could start.
Give the whole flat roof a seamless, fully watertight finish — including every edge, upstand and outlet.
Scaffolding was erected at the side of the property to give safe access to the roof and a secure working area.
The existing roof areas were thoroughly cleaned to remove dirt, debris and surface contamination.
The flat roof surface was prepared for the new system, along with all perimeter details, upstands, abutments, outlets and junctions. All surfaces were left clean and dry before application.
The Liquid 10 waterproofing system was applied across the roof in line with the manufacturer's installation requirements, covering edges, upstands, outlets and penetrations.
Critical areas and roof details were reinforced as the system specification requires, then the required coats were applied for a seamless, durable finish.
