Frequently Asked Questions About Underground Bunkers

Can I install an underground bunker in North Alabama clay soil?

Yes, but clay soil requires special drainage considerations. We install French drain systems around the bunker and use waterproof membrane coatings on all concrete surfaces. Many Shoals area properties have limestone bedrock at 4-6 feet, which we can work with for bunker installation.

How deep are underground bunkers installed?

Standard underground bunkers are installed 4-6 feet below grade. The exact depth depends on your property's soil conditions, water table, and limestone depth. We assess all these factors during the free site evaluation.
