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 is 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. This sheet also outlines both the benefits of performing adhesive-bonded repairs as well as the considerations which must be made before committing to resin repair.
