What procedure is recommended to stop cracks in bulkheads from widening?

The recommended procedure to stop cracks in bulkheads from widening involves drilling 1/4 holes at the end of the crack and plugging them. This method is effective because it essentially relieves the stress concentration that often builds up at the terminus of a crack and helps prevent it from propagating further.

By creating a small hole at the end of the crack, the technique not only interrupts the potential for crack extension but also allows for better management of any environmental factors such as moisture, which can exacerbate the problem. Plugging the hole can further seal the crack, minimizing the risk of water infiltration and subsequent damage.

In comparison, sealing cracks with epoxy or applying a layer of sealant might address the visual aspect of the crack but may not effectively prevent the crack from widening due to internal stresses. Covering the crack with a metal plate may provide a temporary solution, but it doesn't address the underlying issue causing the crack and can often mask ongoing stress problems. Thus, the drilling and plugging method is a more proactive approach to ensuring long-term structural integrity.
