Cinder block enclosure

[Deigo]

Hi everyone,
I built a cinder block burrow but my issue is that Diego my desert tortoise is digging under the cinder blocks and I had to take him out because I am afraid the blocks will collapse on her. Any suggestions, please?

I have 1 inch square wire ( chicken wire type but stronger) as a base beyond the perimeter where Cinder block wall is. Then a layer of small pebble/ stones which i washed before putting in with substrate on top. Cinder box is the perimeter and I build up soil on the outside to wedge in place. Hope that helps?

Lots of people who have a burrowing species will bury a cinder block or two below the ground also.
