Most do, but we have a selection of patio ponds that have been created for a flat surface, therefore no digging is required.
We also have more Self-contained units that can be placed on a patio area.
Alternatively you can dig your pond into the ground half way and landscape around the protruding other half, this creates a nice raised effect and results in less digging.
Want to see a real example of a water feature built without a traditional dug pond? Take a look at our pond-less water feature installation project.
