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 Epoxy Glass
Rods, often called '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 hammer-in plastic injectors to 10mm diameter
holes. These have
one-way valves inside to prevent resin backflow.
Inject Thixotropic Epoxy Injection Resin, slow
set version, using a Syringe.
Once the resin has set the injector head can be
cut off, or drilled out and filled.
