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.
