Construct & maintain
The challenge was to construct a large natural self-sustainable pond.
The initial stage was to create the shape and depth by removing the soil. A drainage system was then put in place under the pond to prevent water build up (excessive rain fall and flooding) between the soil and liner which could potentially lift liner making the pond overflow. This was done by another contractor working in conjunction with ourselves.
The profile of the pond was created by making shelves for deep water, midwater and marginal planting. We applied a layer of sand followed by covering with a protective pond liner underlay ensuring a shield from any sharp objects.
Once this is done we covered with the pond liner. We used a good quality Butyl rubber liner as this gives high flexibility to create natural contours to the pond profile.
The pond can now be filled. Once filled, the pond must be left for at least 48 hours to allow the chlorine to dissipate before any planting can take place.
After 48hrs has passed we can plant with the correct amount and type of plants to create a natural environment for a self-sustainable pond. After a minimum period of 72 hours, once the water chemistry and temperature of the pond had stabilised fish and other pond life can be added in stages over a few weeks.
