Types of Work Involved
Adamson Construction was contracted by a local hospital to refurbish an existing roof membrane, as the existing roof membrane had failed to cause water ingress. The first task was to erect the safety handrail and scaffolding access all around the building. Repair works were then completed to the existing guttering at joints and the drip beads were replaced all around with Galvanised metal drip beads. The existing de-bonded and failed roof felt was then stripped throughout and a new felt bridging membrane laid out and secured with Galvanised tacks. Galvanised metal primer was applied to the edge trim all round to ensure the Sikalastic adhered.
Two coats of Sikalastic 618 glass-reinforced roofing membrane were applied. The first coat was applied at 1.5L/m2 then the Sika Reemat dressed into embedment coat whilst still wet and back rolled to wet out. This was allowed to cure then the second coat of Sikalastic 618 was applied at approximately 0.75L/m2.
