During recent renovation work at the Cwm Primary School in Swansea, South Wales it was noticed that one of the main structural timber support trusses was badly damaged. The schools major concern was the Health & Safety of the it’s children, and turned to Rentokil Property Care to investigate the problem and provide an effective solution that would prevent any further damage to the roof.
Local Rentokil Property Care surveyor Huw Jones carried out a thorough survey inspection and swiftly identified the problem as Dry rot (Serpula lacrymans). This had severely affected the bearing ends of the beams, as a result of moisture ingress over time.
Rentokil’s cost effective solution was a combination of protective treatment and sensitive repair. Any evidence of the Dry Rot fungi (mycelium) was removed from the timbers, and a localised fungicide treatment was completed to help prevent any further infestations developing. Repairs were sensitively carried out to the tie beam and associated rafter. This was done by forming slots in the parent beam and using a Timber Resin Splice (TRS) with structural bars and epoxy resin. Prior to the Timber Resin Splice sections installation, the end grain of the original timbers were treated.
Belinda Helme, Local Property Care Branch Manager, commented: “The use of a Timber Resin Splice allowed us to repair the damage that the Dry Rot had caused, at a cost effective price for the school.”
This was a considerable benefit, as the only other viable, alternative to the Resin Timber Splice would have been to replace the entire roof truss. This would have resulted in a great deal of additional cost and time in replacing these timbers. Cwm school now also benefits from a Rentokil Property Care 30 year guarantee, which means the school has peace of mind that the completed work is guaranteed for the foreseeable future.
