Abstract: A kit for encapsulating a length of pipe features first and second foam sections cooperatively shaped to form a cavity with open ends in a working configuration of the foam sections for receiving the length of pipe therein. A low density foam, which is lower in density than the material of the foam sections, fills an unoccupied space in the cavity so as to provide cushioning for the length of pipe such that movement of the length of pipe within the cavity is permitted and stress on the length of pipe is reduced. The foam sections may be reinforced with reinforcing membranes carried in a main body of the respective foam section. The reinforcing membranes may act to hold the foam material of the respective section together and to prevent puncture along a full thickness of the foam sections from abrasive debris in the ground.
