This could involve injecting epoxy resin to fortify the foundation wall, or even applying a waterproof membrane to prevent water penetration. It's vital to initially by assessing the root cause – substandard drainage, shifting soil, or tree root intrusion – as simply patching the crack without resolving the underlying cause will likely lead to recurrence. Always evaluate consulting a licensed structural engineer for a detailed inspection and personalized guidance before proceeding with any repair.
