Install a garden pond: install

Step 1: Determine the location of the pond

To enjoy the benefits of the sun your pond must be facing due south. However, we advise you to install in the south of your pond a large group of aquatic plants in order to avoid that it warms up too much. The temperature of the water must never exceed 26 degrees, otherwise the inhabitants of the pond will be in danger.
Avoid installing your pond under trees, the fall of the leaves would cause a surplus of organic matter which would prevent the good development of the aquatic environment.

Step 2: Determine the dimensions of the pond

The area of ​​the pond will be decided according to the available space and your desire; pools of less than four square meters are strongly discouraged.
The depth must be greater than 80 cm in order to maintain a certain amount of frost-free water during winter periods.
The slopes must be gentle to allow animals to enter and especially out of the water.

Step 2: Excavation of the pond

Delineate with sand the contours of your pond
Then dig the interior of the lines to the desired depth
Set up a cornice on the pit contours approximately 30 cm deep and 25 cm wide.
The walls of the cornice should have a slope of about 20 degrees.

Step 3: the borders of the pond

Remove a strip of soil 45 cm wide and 5 cm deep outside the sand mark or you will install the borders of your pond.
Put a plank across the pond and install a spirit level on it. Check that the perimeter of the basin is perfectly horizontal.

Step 4: The bottom and the walls of the pond

Clear the bottom of your pit of any stones and other roots that could rip your tarpaulin.
Hand-compact the walls of the basin to prevent the "soft areas" from sinking.

Step 5: Installing the tarpaulin

Cut the tarpaulin to the desired size then put it roughly on the pit.
Temporarily lay bricks on the sides of the pit to hold the tarp in place.
Put some peat from a natural pond in the bottom of the tarpaulin and then pour a little water. Under the weight of the liquid, the coating will gradually follow the shape of the hole. Remove the bricks as you go and arrange the folds of the tarpaulin.
Fill the basin until the water reaches the edges of the hole.

Step 6: The edge of the water

Cut out the covering that protrudes from the pelvis to obtain a 15 cm hem on the contours of the pelvis.
Then bury the outer edges of the liner, letting it protrude 5 to 10 cm inwards. Tarpaulin
Finally, hide the remaining tarpaulin under the flagstones, leaving a few centimeters of tarpaulins on the inner edge of the pool.
All you have to do is decorate your pond with adapted aquatic plants. We do not recommend introducing exotic plants and animals that would endanger local flora and fauna.

If young children are going to your garden, we advise you to install safety barriers at the edge of your pond.
