Hiding Barrel Waterfall Top: Rock Stacking & Cement Board Fix

A 55-gal barrel waterfall shows its ugly top — wood boards rot, faux rocks cost too much. Solution: build a rock facade using the barrel as structure.

Cheap, Natural Fix

1. Stack smaller rocks around barrel base — mortar or dry-stack.
2. Place flat rock across back (where opening shows) — spans top.
3. Stack more rocks on flat rock — irregular, natural look.
4. Adjust until water flows over rocks, not barrel lip.

If Wood Board Rots

• Replace with **cement board** (HardieBacker, Durock) — $10/sheet, won't rot.
• Cut to size, screw to barrel rim, stack rocks on top.
• Seal edges with silicone.

Pro Tip

Use **waterfall foam** (black expanding) between rocks and barrel — locks rocks, seals gaps, directs flow. $15/can.

Your pond is beautiful. The barrel's a smart core. Dress it with rock — it disappears.
