Repairing Animal Burrows Under Concrete Steps with a Block Barrier

Animal burrowed under concrete steps attached to foundation. Animal gone. How to fix and prevent recurrence.

Fix

1. Pack topsoil tightly into void with broom handle/shovel.
2. Dig 12 in deep trench along step base.
3. 2 in gravel base, compact.
4. Lay 4 in concrete blocks (cinder blocks) tight to step bottom.
5. Backfill soil to grade.

Why It Works

Blocks extend foundation downward. Animals would have to dig deep, around, and up—major deterrent. Worked for dog digging under fence.
