Cracks in Foundation

[Michael Campione]

My property is in the Dallas Metroplex and everyone knows how the soil and foundations are a problem to begin with.
If a tenant is responsible for keeping the lawn watered and the irrigation clock was turned off every time I checked it.
(They also complained that it used too much water.) I told them numerous times they needed to not tamper with the clock and they have denied tampering with it. Now that they have moved, I have a crack in the patio. Can I hold them liable for the repairs.
