BS EN 17418:2021

This standard BS EN 17418:2021 Two-component epoxy and polyurethane adhesives for on-site repair of cracked timber structures. Testing, requirements and repair strength verification is classified in these ICS categories:

• 83.180 Adhesives

This document specifies test methods and requirements for two-component epoxy and polyurethane adhesives for on-site repair of cracks in timber structures made of strength graded structural timber with rectangular cross-section, structural finger-jointed timber, glued solid timber and glued laminated timber made of softwood species by injection of the repair adhesive with glue line thicknesses up to 8 mm. The adhesive can also be used to rehabilitate cracks in the area of joints made by nails, screws, dowel-type fasteners and dowels with threads. The adhesive can also be used to fill gaps between the faces of structural components. This document addresses exclusively adhesives which fulfil the requirements according to Clause 8.

This document also covers the repair of surface treated wood. It does not cover the repair of preservative treated wood, modified and stabilized wood with considerably reduced swelling and shrinkage properties, e.g. acetylated wood, heat treated wood and polymer impregnated wood.

The adhesive is intended for the repair of load bearing timber structures not subjected to temperatures more than 60 °C over a longer time in service classes 1 and 2 according to EN 1995?1?1 which are loaded predominantly static or non-fatigue quasi static, see EN 1990 and EN 1991?1?1. A verification of quality and bond line integrity of the on-site repair bonding is given in an informative Annex A.
