Adhesive-bonded repair systems for structural timber

TRADA image

Although there is an increasing interest and application in using adhesive-bonded connections for new buildings, the main demand for this technology in the UK has been for repairs to structural timbers. The original concept was aimed at repairing historic structures. However, the technology is increasingly being used for repairing modern materials such as glulam and other engineered wood products.

These repair systems can preserve historic surfaces while maintaining the serviceability of the building. Moreover, where changes of use require greater load bearing capacity, these systems may provide the necessary reinforcement without altering the appearance of the original timber.

 

This Wood Information Sheet (WIS) is an overview of the ways in which adhesive formulations are used in repair work and offers guidance on the suitability of adhesive-repair techniques for surveyors, designers and owners or keepers of structures.


Contents:

  • Repair strategy
  • Applications of epoxy systems
  • Conditions of use
  • Functions
  • Structural action
  • Typical repair situations

 

This Wood Information Sheet was reviewed in July 2021 and minor amendments were made including changes to Table 1 and Figure 2.
