Pouring The Concrete


When you come to the point where it is time to pour the concrete base, it is also time to reflect for a moment to make sure everything is ready.

Shaping The Base


When the base is in place and the walls build up to a certain level the floor can be shaped or benched. Some people feels that it is not necessary to shape the floor, stating that if the return flows into the pond is angled correctly, waste will be forced towards the bottom drains. It may be true in some cases, but I have yet to see a pond with a level floor that do not have an accumulation of waste matter at one place or the other. The motto should be: “Do it right first time!” Believe me; to change any aspect of a pond’s design after the pond has been stocked is expensive and frustrating. Housing fish in temporarily accommodation while you effect changes, more often than not leads to complications and losses.

The Concrete Base


There are many ways to design and construct a concrete base for a pond. The specific design will depend on various factors, but mainly on the skill and experience of the pond builder. The base can be constructed in layers or as a single cast base. A more advanced method includes the curved bottom. All these will be demonstrated individually in this article. Benching the floor will be discussed elsewhere in this series.

Getting The Levels Right


When sufficient progress has been made with the excavation work for the pond, it will be necessary to determine the levels. The most important thing to consider is the height that you want the final water level of the pond to be. Every measurement will be taken from that specific point, even the levels that must be determined later like the filter system

Digging the Pond



Now you have done your homework and considered all the options. The excavation area has been marked and adjustments have been made. Adjustments always happen, don’t worry. It is time to bring the spades or if you can get it to the site, an excavator. For various reasons, a pond should be as deep as possible in South Africa. The reason may be from ensuring temperature stability, protection against extreme climate and larger volume of water to keep the fish in. There are also different views on the effect of pond depth on the development of the fish, but the advantages of a deep pond are so obvious that it makes the whole debate about development of Koi in deep or shallow ponds obsolete.
