Rock Quarry Blasting Home Damage Lawsuits

When the quarries are blasted with explosives to break up the rock, some energy from the blasts escapes into the atmosphere. This generates air-blasts or vibrations. Repeated exposure to these vibrations creates damage to structures near the quarry. Additionally, some energy from the blast vibrates through surface soil and limestone.
