Raised ponds make excellent water gardens. These ponds are easy to install, and they will not collect debris, like in-ground ponds. But raised ponds do have a drawback -- the installer must provide a surround for the sides of the prefabricated pond, and a cap must cover the edges of the raised pond and wall surround. Nevertheless, the edges and sides of a raised pond can be covered quickly and with minimal cost. Most ponds can be finished within hours and most likely cost less than £65 to surround and cover.

Things you need
- Retaining wall blocks
- Wall caps or pavers
Purchase retaining wall blocks, as well as wall caps or pavers, from your local home improvement centre. Purchase an appropriate number of retaining wall blocks to cover the vertical surface area of the raised pond walls. Purchase enough wall caps or pavers to cover the perimeter lip of the pond walls. If your raised pond's sides are adequately covered or finished, skip to Step 3. Otherwise, move to Step 2 to finish the sides of the raised pond.
Stack the retaining wall blocks along the outside of the raised pond walls. Alternate the blocks with each course, creating a standard running bond. The retaining wall blocks do not need mortar, instead the blocks stack at a slight angle, or batter. This batter allows the blocks to stack securely, without need for reinforcement up to 4 feet. If your raised pond edges are higher than 4 feet, wall tie-backs will be necessary. However, most raised ponds do not stand higher than 2 feet. Stop stacking the retaining wall blocks when the top of the highest course is level with the edge of the raised pond.
Lay the pavers or wall cap over the top of the pond edge and the highest retaining wall block course. The paver or wall cap should completely cover both the retaining wall and the pond edge. In most cases, the paver or cap should extend slightly over the water and over the top course, creating a shadow line to obscure the wall surfaces below. In some installations, the pavers or caps will need to be tied down. Wrap heavy gauge steel wire to the bottom edge of the pavers or caps and secure them to the pond and retaining wall.
If the pond wall and veneer are concrete or standard masonry, you may prefer to set the pavers and caps in a thin mortar bed, securing the pond edge.
Adorn the finished edge and wall with planters, creeping plants or ornaments.
