X, C and U Exclusions

Exclusions to Property Liability forms aimed principally at contractors and excavators. The exclusions deny payment for loss due to Explosion (X), Collapse (C) or Underground Damage (U).

Underground damage includes damage to wires, conduits, pipes, mains, sewers, tanks, tunnels, any similar property beneath the surface of the ground or water caused by and occurring during the use of mechanical equipment for the purpose of grading land, paving, excavating, drilling, burrowing, filling, backfilling, or pile driving.
