    Abstract: A protective shield for elongated underground utilities such as an elongated underground utility strand or pipe is disclosed. The protective shield includes a foldable elongated flexible sheet of shock absorbing material adapted to both overlie and underlie the elongated underground utilities. The foldable elongated flexible sheet of shock absorbing material includes at least one longitudinally extending fold line that extends in the same direction as the elongated underground utilities and may be transversely offset from a longitudinal midpoint of the foldable elongated flexible sheet of shock absorbing material. In some instances, the foldable elongated flexible sheet of shock absorbing material may include two longitudinally extending fold lines that are transversely offset on each side of a longitudinal midpoint area of the foldable elongated flexible sheet of shock absorbing material.
