If there is excessive water loss, sealing the garden pond is particularly important, otherwise the biological balance will be disrupted. In order to locate all leaks, plants and fish must first be evacuated before the walls and floor are completely sealed.
How can I seal my garden pond?
To seal a garden pond, fish and plants should be evacuated, water drained and cracks identified. A foil seal is recommended for concrete ponds, while the same material should be used for patching foil ponds.
Primarily older ornamental ponds tend to leak over the years, especially if they are made of concrete and the first hairline cracks form. But liner ponds also show certain signs of aging and quickly allow large amounts of water to seep away. In masonry ponds, it is sometimes difficult to reliably locate theleaks If only the bottom area is affected, applying an additional layer of clay can help. Which in turn means that in order to seal the garden pond, many or even all plants and animals must first be evacuated from the pool.
Remove leaks from the garden pond
Once the water has been drained and the ground has been cleared, the search for cracks can begin. Roots that have grown through are often the cause of damage, which should now be easier to identify. Experience has shown that sealing a garden pond only leads to lasting success if the entire pond is renovated,instead of just patching individual damaged areasSince a general repair can usually only be carried out with an unreasonably high expenditure of time, materials and money, it is advisable to seal ponds made of concrete with films of the highest possible quality. Specialist retailers have several types available for this, the most common consist of:
- Polyvinyl chloride (PVC);
- Polyethylene (PE);
- Synthetic rubber (EPDM);
What to do if the liner pond leaks?
Here, too, a thorough cleaning is required first in order to then find out what type of pond liner it is if it is to be repaired by gluing or welding. Repairs will only be successful if they are made with the same material and the film thickness is identical. It is also important to ensure that the connection points of the film strips overlap as generously as possible. Starting at the edge of the pond and with sufficient overhang, the film is first laid over the embankment in the direction of the hollow and bottom to the opposite side - lane by lane. The protruding endscan be sunk into the ground or hidden behind additional paneling.
Tip
If you want to seal a cuboid garden pond, the strips are best cut to fit. The inlets and outlets of the pond must be insulated particularly carefully towards the foil so that water does not seep into the ground in an uncontrolled manner later.
