Method and apparatus for protecting drainage pipe installed underground
A pipe protection apparatus includes a sheet of permeable material having an inner surface and an outer surface and a longitudinal direction and a width direction defined by two edges of the sheet along the longitudinal direction. A fastening structure is configured to join the two edges to form a seam as the sheet of permeable material is wrapped in the width direction around a drain pipe configured to be installed underground to form a sock along the longitudinal direction. The sock is configured to be installed underground with the drain pipe about which it is wrapped, yet to remain for a service life in non-bonding contact with the pipe.
