Things You'll Need:

- Pump
- Pond liner
- Waterproof adhesive

Step 1
Decide which style of slate water wall you would like to build and purchase the materials at your local garden supply store or home improvement store. Stacking slate creates a beautiful water wall with nooks and crannies for the water to meander through, but it requires a lot more material than the tiling method. The pond liner is your water wall's reservoir and may be decorated with stacked slate or other stones. Read the manufacturer's specifications and get a pump with enough power to send the water all the way to the top of your slate wall. River rock works as a fill for the reservoir, or you could fill in with plants.

Step 2
Clean the exterior wall if you plan to tile the slate to the wall. You can use mastic or other adhesive formulated for exterior use. Grouting the slate is not necessary if you place the slate so that the panels touch, or you could use spacers and grout as a design element for your slate water wall. Let the mastic dry before you grout and make sure the grout is dry before you turn on your water wall.

Step 3
Dig a hole for the pond liner or build your water wall reservoir with stacked slate. Place the pump in the reservoir and attach the plastic tubing. Run the tubing up the side of the slate wall or unobtrusively through the stones to the top. Wide slate water walls may need more than one pump for complete water flow coverage.

Step 4
Add plants in and around your water wall reservoir added appeal. Water lilies and cattails bring natural beauty to your pond reservoir.
-
Step 5
Fill the reservoir with water before you plug in the pump.
