5,000 tonnes of IKO Permaphalt Roofing overhaul to heritage building

Over 5000m2 of Mastic Asphalt roofing was scheduled by English Heritage/Historic England for an extensive overhaul at Hurst Castle.

Throughout the project there was very close consultation with all agencies, local and national suppliers to achieve like for like replacement of the original makeup, adjusting plans at short notice as variations were uncovered. The work included a complete strip up and reinstatement of the East wing with concrete repairs to structural cracks and 150 tonne of sand and cement screed under 300 tonne of IKO Permaphalt.

The West wing underwent extensive asphalt repairs throughout. The majority of work was carried out on a significant fall from 10%-20% on the gun emplacements, the asphalt detailing included upstands, downstands, vertical, capping, drips and gutters.

Challenges on this project came about due to the unique position of the castle, materials and waste were transported along a 1.5 mile gravel spit by tractor and were lifted on and off the roof by telehandler, including the three 2 tonne asphalt cookers which were used to prepare the IKO Permaphalt, personnel took the 20 minute ferry crossing to and from site daily.

The castle remained open to visitors throughout the project adding an extra planning element to the safe execution of this 6 month project. The site was well managed and an excellent H&S record maintained by the crew based there in liaison with the site agent.
