Resin repairs to timber structures

Abstract Resin methods to repair timber structures are relatively new with a history of use of approximately 25 years. Architects and engineers have mixed feelings about their use with reservations such as: (1) unknown or unreliable structural performance, especially with timber at high moisture contents, and (2) unproven durability and inability to conform to conservation recommendations. This paper discusses tests carried out to assess the performance of resins used in timber repair and discusses conservation recommendations which also prevent more widespread use of the technique.
