Vibration Damage is a insurance issue, in that every time a home owners feels vibration from a construction project, the owner claims damage occurred. Frequently, the damage is obviously preexisting. But occasionally damage from vibration does occur. Any time a compaction roller gets closer than 25 feet to a residential concrete basement, built to just the minimum Alberta Building Code standards, the lateral forces are high enough to potentially cause damages. Drop weight concrete breakers and big back hoes which lift and drop concrete, pile driving operations, deep soil compaction, and well fracing all can cause damage.

Wet soils and vibration sensitive silts are particularly bad. Wet soils lateral pressures attenuation is low. Vibration sensitive silt can cause settlement at considerable distance.
