Worried about crushing tarantula

[Zannee2000]

Hey so my spider has dug a little trench underneath this piece of bark in her container and it’s starting to shift downwards should I be worried it might crush her or does she know what she’s doing

Shes fine. Corkbark is super light, this behavior is really common with spiders. She probably has tossed some thin webbing under the cork which is super strong also.
