How to make your plastic pond and waterfalls look like stone and rocks

Updated February 21, 2017

Plastic ponds and waterfalls fill landscapes with the tranquil sound of flowing water. Use them as a focal point in a flower bed or as a relaxing feature beside a patio. Water is a natural feature that fits right in among plants, but the plastic makes the pond stick out, emphasising that it is not a natural pond. PVC pond liners give homeowners the ability to blend the pond and waterfall with the surrounding landscape. A PVC pond liner coated with real pebbles or printed with images makes the pond and waterfall look like real stone and rocks.

  1. Lay the plain pond liner over the plastic pond and push it down into the grooves, removing as many wrinkles as possible; this liner requires no adhesive.

  2. Trim the edges of the plain pond liner to fit the size of the pond, leaving a 15 to 20 cm (6 to 8 inch) overlay around the pond edges.

  3. Lay the plain pond liner over the waterfall path with a 15 to 20 cm (6 to 8 inch) overlay on both sides. The liner should overlap with the pond at the end of the waterfall path so that water flows into the pond easily.

  4. Coat the the dry, plain pond liner inside the pond with pond-liner adhesive, and then coat the back of the PVC pond liner that has pebbles or stone pictures. If pebble or stone liners are only available in-single size sheets, use as many sheets as needed to cover the plain pond liner.

  5. Heat the adhesive on the back of the pebble or stone pond liner with a hair dryer on the hot heat setting. Heating the adhesive makes it easier to adhere it to the other pond liner.

  6. Put the pebble or stone pond liner in place over the plain pond liner, working from one side to the next. Smooth out the wrinkles as much as possible, and allow the adhesive to dry completely for about 1 hour.

  7. Add the pebble or stone liner to the waterfall path in the same way. Apply glue to the plain pond liner and the pebble or stone liner, heat the glue and smooth it into place.

  8. Cover the overlapping edges with real stones, rocks and pebbles; start by adding larger stones, and then fill in the gaps with smaller rocks and pebbles. Try to use stones, rocks and pebbles that match the pebbles and stones on the PVC pond liner.

  9. Fill up the pond, hook up the pump to the waterfall and turn on the water.

  10. Tip

    You may be able purchase pond liners with larger dimensions than needed for your pond, trim the excess liner, and then use this to line the waterfall. This saves money from purchasing two separate liners for the pond and waterfall. If the pond already has a plain, sheet plastic liner, simply wash and dry the liner completely and adhere the PVC pebble liner to it. PVC is a widely popular material for pond liners and adhesive is recommended to apply it to another pond liner. Pond liners made from other types of plastic may not require adhesive or a plain liner backing and can simply be laid in place over the plastic pond.
