big daddy underground tree root and 1 reason why NOT to backfill with clay, eh

Eastpointe MI, block basement walls.
Underground root and clay caused multiple exterior cracks in block walls which ummm, then allowed water to enter the basement causing some mold and efflorescence on interior block wall.

Same house…
The SIDE wall was previously ‘done’… done by a moron. Backfilling with the same excavated clay is incompetent and not what’s best for the wall, for the homeowner. The soil SETTLES and as it settles it pulls down the visqueen and the tar that was applied to the dumb wall exposing the upper parts of the dumb exterior cracks in wall
