Disassemble the paver blocks and set them aside. Tap the collapsed blocks free from the edging with a mallet.
Shovel the foundation of the paver wall to a depth of 8 inches. Fill the dug-out foundation with approximately 6 inches of gravel. Pack down the gravel in an up-and-down motion with a tamper.
Fill the remaining 2 inches of the dug-out foundation with sand. Lay the paver blocks end to end along the sand foundation. Place a level on each block and tap each block with a mallet to adjust it for level.
Stack additional layers end to end on top of the first layer of paver blocks. Stagger the joints so that the paver wall will be sturdier.
