UBBINK® offers the widest selection of pond liners on the market. Pond liners are made of two
types of material:
✓ PVC (thermoplastic type, flexible polyvinyl chloride): AquaLiner®
✓ EDPM (elastomer type, ethylene-propylene-diene terpolymer: AquaFlexiLiner®
These two flexible and waterproof geomembranes are available in several thicknesses and in
the form of rolls cut to the linear metre or in pre-cut folded bags of different lengths and widths.
With its experience gained over 40 years, all pond liners meet the EN 13361 standard. This is why

1. The shape 4. Laying the liner
After deciding on the location and shape of the pond, mark the out- Unfold the pond liner and pull it over the hollow. Lay the pool liner all
line. A garden hose and some stakes of wood will be useful. You can around, letting it extend by 30 to 50 cm. If you now fill the pool with
also mark the marsh and shallow areas in this way. During this phase, water, the pool liner will slip and gradually settle in the right position.
corrections can still be made without any problem. To prevent the pond from losing water unnecessarily, create what is
called a capillary dam: the pool liner at the edge is not simply laid flat
and covered with earth, which would allow water to escape easily, but
rather hold it upright and cut it a little above the ground level. The top
edge of the liner should always be higher than the highest water level.

2. Digging
Dig down vertically to mark the final outline. Remove the layers of soil
gradually. The marsh and shallow areas will be covered later with a
layer of about 10 cm of UBBINK® gravel or substrate, which is impor-
tant to remember when clearing. Keep in mind that the edges of the 5. Bank landscaping
pool must be level (check, for example, with a batten or spirit level). For the development of the bank area, it is advisable to use UBBINK®
culture beds, woven in nylon or coconut, as well as UBBINK® coconut
irrigation bags, with pockets in which the plants are installed to hang
in the pond. These plant beds and irrigation bags are fixed in the
ground with hooks. After some time, once the plants have taken root,
the edges of the liner will no longer be visible.

3. The substructure
The next step is to remove all sharp objects and roots from the
ground. A layer of sand must then be laid to protect the liner. We also
recommend UBBINK® pond geotextile felt, a particularly resistant and
rot-resistant synthetic material.
