Eligible structural damage for sinkhole insurance coverage generally includes foundation distress caused by direct sinkhole activity. Because coverage specifics vary between standard sinkhole activity riders and catastrophic ground cover collapse coverage, the type and severity of damage determine eligibility.

Key aspects of eligible structural damage include:

• Foundation Cracks: A cracked foundation is a primary indicator of sinkhole activity and is often eligible for claim consideration if documented early.
• Broad Foundation Damage: Standard sinkhole insurance typically offers broad eligibility for foundation issues, including settlement caused by subterranean ground depressions.
• Structural Instability: This includes lateral movement, wall cracking, and overall foundation instability that requires stabilization.
• Severely Compromised Structures: Under Catastrophic Ground Cover Collapse coverage, damage is usually only eligible if the structure is condemned or so severely compromised that it is no longer safe.
• Approved Stabilization Methods: If a claim is approved, coverage often extends to engineered solutions such as helical pier systems or steel piers designed to provide load-bearing capacity and structural integrity.

To confirm eligibility, insurers like Tower Hill Insurance typically require a formal assessment from a licensed structural engineer and thorough documentation of the damage.
