Preformed ponds

UBBINK® offers the widest selection of preformed ponds on the market. They are made in three
types of material:
✓ polyethylene by a stamping process.
✓ high density polyethylene by a rotational moulding process.
✓ polyester by a contact moulding process based on a polyester catalysed resin.
The pond shapes vary greatly: some are strictly geometric, others have natural forms with banks,
marshy areas and planting levels at different depths. With more than 40 years of experience, all
preformed polyethylene ponds are TÜV certified. This is why UBBINK® can unhesitatingly offer a
10 or 15-year guarantee for preformed ponds.
