Repair Method

Cracks, shakes and fissures 5mm wide and below require injection rather than filling (for the filling of wider cracks see Filling & Dowel Fixing). The injection method uses an epoxy adhesive and may be supplemented with Dowels if the defect extends more than 30% through the timber. Consult a Structural Engineer before proceeding.

Clean out cracks with a saw blade and vacuum clean.

Fit injectors using quick setting paste and then remove blanking nail to open hole.

Connect injector via plastic tube to cartridge of epoxy crack injection resin.

Remove flanges, grind off paste and cosmetically finish, if appropriate, with epoxy mortar.
