How to Repair Glulam

Glulam is a kind of artificial, composite wood, consisting of laminated bits of timber glued together. It used in the building of domestic houses as well as larger buildings. It is particularly strong and has even rivaled steel structures' strength-to-weight ratio. Often, glulam beams are used in the ceilings of houses; just as often, these structures can crack, weakening the integrity and support of the ceilings. It is important to have an idea about how to fix such a problem. However, it is suggested one has an advanced understanding of home repair before tackling this problem single-handed and independent of professionals.

Things You'll Need

  • Electric drill
  • Various drill bits (sizes 1 3/8 inches and 3 inches)

Instructions

  1. Repairing the Glulam Beam

    • 1
      Repairs to a building's glulam beams can be done with the right materials.

      Locate the cracked or otherwise defective glulam beam. Drill six 1 3/8 inch holes in the sides of the beam, from near the underside of the beam to 6 inches above the highest cracks on the beam. Drill six large portholes, using the 3-inch bit; three holes along the underside and three holes on the top of the beam.

    • 2
      Keep the epoxy from leaking out of the beam by applying sealant.

      Squeeze sealant onto the sides of the beam, in preparation for the six rebars. The epoxy paste used has a low viscosity and will travel along drilled-in holes and cracks in the beams; sealing the sides of the beams earlier will not allow this liquid epoxy to escape.

    • 3
      Rebars further reinforce the structural integrity of the glulam beam.

      Fill the six 1 3/8 inch holes with the liquid epoxy. Before epoxy is dried, insert the six 1-inch rebars fully into the six epoxy-filled 1 3/8 inch holes.

    • 4
      Seal the 1 3/8 inch holes.

      Squeeze sealant over the dried epoxy-and-rebar filled 1 3/8 holes.

    • 5
      Use epoxy to fill the portholes for added structural support in the beam.

      Squeeze epoxy through the lower port holes to the point of exiting through the upper port holes on the beam. Allow to dry. This will provide further support to the beam.
