Pond Construction Materials

Pond Size

Ponds can be made to any size or shape but the general rule is the bigger the pond, the easier it is to maintain its water quality. This is because larger ponds have fewer fluctuations in temperature and other water chemistry factors and have a greater capacity to handle pollutants. When planning your pond investigate the overall cost including pumps and filtration systems.

Construction Materials

There are many options for those looking to design and build their own pond. The most popular of these is the lined pond.

Lined Ponds

Liner

When lining a pond, you need a product that will conform to the contours of the pond. Proliner EPDM liner folds and stretches with ease. It is available in widths of 3, 4.5, 6 or 9m and can be easily joined on site using a primer and double sided tape system. Proliner comes in two thicknesses - 0.70 mm and 1mm. The 0.70 Proliner is a versatile pond liner that offers a great balance of elasticity and weight. This is the best product to use for most backyard ponds as it provides excellent protection without being too heavy to manage.

The 1mm Proliner is ideal for larger jobs and where you may wish to place some extra-large boulders in your pond or creek-way. Joining and repairing EPDM liner is made easy with our range of accessory products. Further videos on  joining Proliner can be found on any proliner stock item, open one and scroll to the bottom.

PVC pond liner is another option when constructing a pond out of liner. It’s 0.5mm thick and is also suitable for most backyard applications. Whilst not as flexible as Proliner, it is a cheaper alternative. PVC liner is joined using PVC liner glue or Gold Label underwater sealant.

Plastic Preformed Ponds.

Plastic preformed ponds are ideal for the back yard novice. You need few tools and they can be installed with little effort. Plastic is tough which means you don’t have to worry too much about sharp objects penetrating the pond. Levels are easily achieved when installing preformed ponds by using a spirit level across the pond walls. Preformed ponds are also handy for renters, as you may take them with you when you leave.

Fibreglass Ponds.

Preformed fibreglass ponds have many of the same advantages as plastic preformed ponds and are installed in the same way. Custom designed fibreglass ponds are best left to the specialists. The down side of custom made fibreglass ponds is that they need to be re-sealed every few years which makes them higher in both cost and maintenance requirements than ponds constructed with pond liner.

Concrete Ponds.

Concrete ponds must have a physical barrier between the concrete and water to prevent lime in the concrete negatively affecting the pond’s water chemistry. Clearpond Pondshield starter or Pondshield Professional is ideal for this purpose. Pond liner can also be used for sealing concrete ponds. Concrete can be very unforgiving when it comes to installing the plumbing and electrical work and it can be quite expensive to alter a concrete pond once built.

Raised Brick Ponds

Raised brick ponds have similarities to concrete ponds in that they must be sealed with either fibreglass or a render and sealant. Brick ponds will also move over time resulting in cracks and the need to resealed every few years. Pond liner is the best option for sealing brick ponds because the pond can move and crack without affecting the liner. Liner can be glued, capped off by brick or tiles and a new product which is attached to the brick, Clearpond Liner Grip Clip, which clips the liner into place and can be trimmed neatly off.
