Case Studies

Rotafix in association with the Malaysian Timber Industry Board and Woodfields Group of Companies are pioneering the use of Glulam in construction. Glulam is bonded, laminated timber beams and this short film shows how it works.

The Ballycopeland Windmill in Millisle, Co. Down is prime example of low disturbance methods reducing the cost and time associated with making an essential repair. The main beam on the fan table supporting the rear fan had decayed and needed to be replaced. This case study outlines the repairs using TG6, Rotafix Structural Adhesive, Bonded in Rods and Timber Resin Splice.

The Coronarium Bridge in the basin of St Katharine’s is a cantilevered rising public footbridge with each side consisting of two arms and a counter-weighted section supported by a pivot on top of the portal beam. Over the years the bridge has been subjected to the general usage, weather as well as the occasional knock from an errant boat that has resulted in a number of structural issues that have led to decay and failure. This case study outlines the repairs using TG6, Rotafix Structural Adhesive, Bonded in Rods and Timber Coatings.

Chigwell School in Essex is a Grade 1 listed building dating back to 1816. A leaking roof has led to long term decay to main structural elements of the roof structure. Using TG6 as a bearing surface it was possible to repair in situ the roof structure with minimal disturbance.

Chetham’s Library, which was founded in 1653, is the oldest surviving public library in Britain. The building that houses Chetham’s is even older it was built in 1421. The beautiful old sandstone buildings house a magnificent Library with rooms lined with ornate oak paneling to the walls and ceilings. Previous attempts to strengthen the roof have failed. This case looks at the sympathetic strength upgrading using TG6 and carbon fibre plates.

This case study focuses on the repairs to the log cabin suffering from water ingress as a result of wet rot, open joints, and fissures in the timber. The Owner uses RSA, Borotreat and Timber inserts to effect essential repairs.
