a padding is placed around an underground irrigation pipe which allows the irrigation pipe to flex and bend when the irrigation pipe is struck or compressed . the padding is preferably a synthetic polymer that substantially reverts back to its original size after the compressing force is removed and is not affected by the elements . the padding is used over the irrigation pipe in areas of heavy traffic over the pipe or areas where the pipe may be struck . the pipe can be inserted into apertures in the padding or slits can be made in the padding to allow insertion of the pipe into the apertures . these channels can be prefabricated or cut into the padding as needed .
