The wooden support beams of a deck are a critical part of its construction. If a beam develops a crack, you need to repair it as soon as possible so the deck doesn't collapse. Use an epoxy adhesive to fill the crack. This adhesive is flexible and will contract and expand with the deck. If the deck cracks further after it's been repaired, you'll need to replace the beam or call in a professional.
