Step 1

Saw the PVC pipe to the desired length (our tunnel is 2-1/2' long).

Step 2

Apply silicone sealant to the bottom of the pipe and attach it to the top of the edging block "road". Backfill soil or mulch over the top of the pipe, leaving a few inches exposed at the ends.

Step 3

Attach river rocks to the pipe ends with silicone; let dry. Gently backfill soil or mulch up the rocks.
