I'm almost finished my first garden RR and I am trying to finish up a small waterfall but I can not find a source of rubber for a liner to go under the rocks. Everywhere I have looked, they only sell rubber liners in large sheets and because my waterfall is small I only need a piece about 24" to 36" square. Is there anything I can use instead of the rubber liner, maybe a plastic tarp that you can find everywhere .

I used fiberglass cloth soaked in a UV protective resin. The fiberglass cloth is available from a plastics store, major home center and repair shops at a reasonable price. The resin can be colored.Cut the cloth to fit. Build a trough, partially fill with resin and pass the cloth through like you would for wallpapering. Place directly on the ground or base materials. The mess will harden in a matter of minutes and is water proof plus non toxic if you have fish. Wear gloves and make sure you work out doors, the resin vapors can be lethal.

I put a pond 8'x15'x 3'deep with a stream ( about 20')runing into it from a smaller pond 3'x2'. I tried comercial pond liners, they leaked, I tried heavy plastic tarps, they leaked. ( I think its because I have children. ) I found that you can by RUBBER ROOFING sheets that are garuented ( on roofs ) for 20 yrs or more. My kids havent been able to poke a whole in it yet! It is a little exspencive but you can by small pieces left over from roofing jobs pretty cheep. Check with your local roofers and see what you can work out. But take it from me, a little more money up front the first time is a lot easier and a lot less exspensive ( not counting work )than tearing apart and rebuilding a project 2 or 3 times

David, even if you use concrete for your pond, it is wise to use a liner under it for the time when it does leak (and it probably will). Go to Home Depot or other home supply company and look in the shower section for PVC shower pan liner. Sold by the foot in various widths. It will work.

$1.69 will buy you a sack of concrete and this will do the job. I constructed a lake, a river, and two rock waterfalls and it only required less than 11 sacks. The concrete can be troweled to any desired shape. No way could I have done this for the same cost with a vinyl liner.
