In addition to the initial out-of-roundness, placement and compaction of the soil beside the pipe can cause elongation (an increase in the vertical diameter) of the pipe. The elongation is dependent on the pipe stiffness, the type of compaction, the percent compaction, and whether or not the pipe is strutted [4].
