    Pipe Eedment Materials The eedment material may be imported, such as a crushed stone, or it may be the ("native") material excavated from the trench to make room for the pipe. The eedment material should provide adequate strength, stiffness, uniformity of contact (i.e., completely envelop the pipe) and stability to minimize deformation of the pipe due to earth pressures.
