The "Rotafix Method" is a system of repairing damaged structural timbers in buildings.

Background

The method of splicing new timber to old timber members was patented by Rotafix in 1996 and has become the industry standard across the globe and is often stated on repair scheme drawings or schedules as repair using the Rotafix Method. Timber Engineering and civil engineering training courses looking at Timber repairs training courses teach this method of repair.

Where Timber elements have been damaged as a result of rot, decay or infestation the Rotafix Method is used to replace the damaged section of timber.

The Rotafix Method is used extensively where there is a desire to retain as much of the original timber elements as possible, for example historic buildings, listed buildings, churches and period domestic properties or where the removal of the timber is likely to impact a significant feature such a roof, ornate ceiling or floor covering. Low disturbance and preservation are often the primary concerns when the method is specified by the Architect or Structural Engineer.

Method

The structural timber e.g. floor joist or roof joist are propped using supports. The damaged timber is then removed. A new timber piece is species and moisture matched to the original and cut to size. The two pieces are then connected using rods, bars or plates combined with an appropriate adhesive or grout. The connecting elements are normally made from Glass Fibre Reinforced Plastic, Carbonfibre or Stainless Steel. The adhesives and grouts used are classified as structural in nature with predictable performance characteristics that have been made within a controlled and certified process.

Applications

The Rotafix method has been applied throughout the UK, Europe, North America and Asia in historic buildings.
