Large garden pond construction on very steep site
A series of images showing the construction of a large garden pond designed to sit in a steep hillside.
Large garden pond installed in a hillside. This image was taken when the pond was less than one year old.
The pond on the day we finished it. Planting was made in the margins about one month later. Turfing to be completed by others.
This is the hillside as it was - and the only access through a 1.10 metre wide gate!
Having stripped off the topsoil, the next step was to excavate to water level. All the arisings from the excavation are going to build up a geogrid-reinforced bank on the downhill side.
Another view of the pond at about 10 months old.
A view of the finished pond and jetty/deck on the day we removed from site.
The upper tier of the downhill bank being built up. The lower tier is covered with polythene to keep the elements at bay. The soil on this site became extremly unstable if it was worked when wet. Reinforcing geogrid was used throughout the bank building process.
At last, we're excavating the pond! Note the built up bank on the downhill side.
Split level jetty/deck made from green oak.
Excavation nearly complete and build up of bank. Ramped path nearly finished
The downhill bank and path dressed in with saved topsoil.
