In certain cases particularly where the function of the component needs to be upgraded. The fissure and re-laminating technique can be supplemented or enhanced by installing shear dowels.
Figures 1,2 and 3 represent the current method of upgrading glulam beams that may have de-laminated due to inappropriate storage prior to installation or over drying due to air conditioning within the building, or over loading.
Step 1 Measure and drill holes from the under side at 30 ° from horizontal NB it is essential to use a guide jig.
Step 2 Inject pre-calculated amount of thixotropic adhesive Rotafix Structural Adhesive into the blind holes
Step 3 Install pre-cut rods into the resin filled holes. Remove excess adhesive. Cosmetically finish with wooden plugs or textured wood mortar TM3.
