Under a Tower Hill Insurance policy, damage must meet a specific structural threshold to qualify as a covered sinkhole loss. Coverage typically applies to the building and its foundation when settlement or cracking is directly attributed to sinkhole activity (subterranean voids (e.g., limestone dissolution) beneath the structure).
Signs of structural damage covered by the policy include:
It is important to note that Tower Hill generally excludes cosmetic or non-structural damage, as well as damage caused by normal wear and tear, erosion from surface water, or gradual settlement unrelated to sinkhole activity. For a claim to be successful, a licensed structural engineer must verify that the damage meets these structural thresholds and is caused by a sinkhole.
The ICC-ES AC358 (Acceptance Criteria for Helical Pile Systems) provides the essential framework we use to evaluate and verify helical pile lateral resistance. Unlike standard design tables, AC358 evaluation reports are based on results from full-scale testing conducted by accredited…
Determining the lateral load capacity for ICC-ES compliance involves a multi-layered engineering approach that combines full-scale laboratory testing, shaft geometry analysis, and field validation. To meet ICC-ES AC358 standards, the lateral capacity of our helical pier systems is determined through…
During the continuous special inspection of a helical pile installation, our team and the assigned special inspector must record specific field data to verify that the as-built foundation aligns with the engineered design and IBC 2026 requirements. We record the…
To ensure a compliant helical pile submittal under IBC 2026, a comprehensive documentation package is required. This package must satisfy the geotechnical, structural, and quality-control standards established in Chapter 18 of the code. The core submittal documents include: As the…
When comparing Polyurethane Foam Lifting to traditional concrete replacement, the longevity of the repair is a significant advantage because it addresses the root cause of the problem. While new concrete provides a fresh surface, it does not fix the underlying…
