Ground Pipe for Retaining Wall Posts (1" Sch. 40 Galvanized)

The ground pipe is the foundation anchor of the HomeBridgePC Garden Retaining Wall System. One pipe is driven into the soil at each post location, providing the vertical stability that holds the GFRC posts plumb and secure against the lateral load of retained soil — no concrete footing, no digging, no equipment required.
