Adhesive-bonded repair systems for structural timber
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.

This Wood Information Sheet was reviewed in July 2021 and minor amendments were made including changes to Table 1 and Figure 2.
Following the publication of two revised standards, this article outlines the changes that have been made and what action should be taken for compliance.

Refurbishment of buildings that are structurally sound is increasingly popular. Timber over-cladding is often chosen to refresh elevations, in order to improve their appearance or weather resistance or protect additional insulation applied to the exterior of a building.
This Wood Information Sheet (WIS) describes cladding over existing masonry-clad buildings where...
In this extract from BM TRADA's Best practice guide to Timber in high-specification buildings, Dr John Williams discusses what to consider when assessing the condition of existing structural timber elements in refurbishment or conversion works.
