3-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.

The Good News About Fiberglass  Koi Pond Liners :

courtesy to :

If you’re thinking about installing a koi pond and aren’t sure which of the various types of koi pond liners is best for your pond, then let me tell you why fiberglass is a great choice!


There are advantages and disadvantages to each type of pond liner and only you can decide which one is right for your pond.


I personally like the fiberglass koi pond liners because they are are both versatile and strong.


They also give you an advantage in designing your koi pond because you can join them together to make a variety of shapes and sizes. You should, however, keep maintenance in mind when planning your design to insure having the best possible water quality for your koi.


You don’t want to have nooks and crannies where decaying organic matter can get caught up or stagnant areas with no water flow.


Fiberglass pond shells are fairly easy to install. Simply excavate, level the shell on 2″-3″ of sand base, install any plumbing you are going to need or want and then backfill the area around the pond.


If you decide to purchase a pond kit, everything you need for your pond should be included and you will have step by step installation instructions. Or you can choose to have your fiberglass pond professionally installed.


Either way it is smart to do some preliminary research so you know what the necessities are and which optional pieces of equipment you might want to include, some of which make pond maintenance a bit easier.


Whatever you do DO NOT neglect to install a bottom drain. It is one of the most important pieces of equipment for keeping your pond clean!


Fiberglass pond liners have several advantages over plastic or rubber flexible liners, and even cement koi ponds, which are often thought to be the longest lasting.


Unlike flexible liners, fiberglass is not subject to rim erosion and punctures, making it structurally more sound. As a result of this it is a more permanent and durable solution.


Fiberglass also resists root damage and sabotage from burrowing animals. Either of these will sometimes cause extensive damage to other pond lining materials.


One of the main reasons I prefer fiberglass over cement is because fiberglass lined ponds are not prone to cracking due to minor ground shifting and settling like cement ponds are. They can also be safer for your koi because they are chemically inert and don’t cause changes to water chemistry and pH like cement can.


Fiberglass is much easier and less expensive to repair than either flexible liners or cement, saving time, work and money!


So, even though cement is the first choice for many, and flexible liners are the least expensive, I personally prefer fiberglass koi pond liners.



4- 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.

Once the concrete has set, you can construct the walls, trapping the polythene membrane between the inner and outer skins as they are built. Although laying concrete blocks and bricks requires skill, it is not beyond the capabilities of the amateur, provided care is taken. Use a simple running bond, each block or brick being overlapped by half of the one above. Build up the corners first, using a spirit level and a set square to ensure that they are vertical and true right angles.

All block and brickwork must be laid so that the faces of the walls are vertical and the individual courses truly horizontal with uniform mortar joints. This may not be particularly easy for the newcomer to achieve, but constant use of the spirit level will help. Moreover, strings can be stretched between the corners to indicate the top of each course.


Another easily made aid is a gauge rod, a wooden batten marked off to indicate several courses with an allowance made for mortar joints between them. Generally speaking, the joints should be about 1cm (3/8in) thick.


After rendering the inner face of the walls, the coping should be put in place to finish the structure. The result will be a neat and watertight construction for a permanent raised pond. A waterproof sealant should be applied to the walls in order to prevent the escape of free-lime into the water.


USING A pre-formed pond


When incorporating a pre-formed pond in a brick surround, it is only necessary to construct concrete strip foundations for the walls. These should be about 20cm (8in) wider overall than the thickness of the walls and about 10cm (4in) deep. When the concrete has set, the pond should be placed in position and its outline marked on the foundations in a similar manner to that used when setting a pond in the ground. Using the marks as a guide, you can build the walls, leaving enough room around the pond to permit it to be backfilled. Again, use sand or pea gravel for this purpose, as you would with a pond in the ground. Then the edge can be finished and capped.


The disadvantage of this method is that the wall and capping create a rather broad edge at the top. While this may be perfectly acceptable with a large pond, this is often not the case with a small structure. In this case, it is better to secure the pond in position, then build the walls closely around it. This secures the pre-formed pond within the walls and makes the edging a relatively simple brick overhang.




If a liner is to be used within a brick or block enclosure, proceed in the same manner as when using a waterproof render and polythene membrane, but omit these from the structure.


Once the wall is nearing completion, the liner can be installed, its edge being trapped beneath the coping stones or a final row of bricks. To prevent any abrasive damage between the liner and the rough masonry, secure fleece or geotextile matting to the surface of the brickwork, using an industrial adhesive.


As an alternative, an attractive raised liner pond can be constructed using timber. This requires a level base slightly larger than the pond’s overall dimensions. Although the timber must be treated with preservative and can be laid directly onto the ground, if the base is concreted this will further reduce the likelihood of the timber rotting.


Such a raised pond can be made from old railway sleepers, although any clean timber with a minimum cross-section of 10 x 15cm (4 x 6in) can be used. Cut the timber to size, carefully notching the ends to form halving joints. Use a set square to ensure that the corners of the structure are at right angles, then fasten them together using dowels or rustproof screws. Make sure that each length of timber is level before positioning the next. Build the timbers up until the desired height is achieved.


The interior of the wooden structure can be lined with fleece to prevent any damage to the liner. Simply tack this to the timber. Then lay the pond liner in place, making substantial folds in the corners if the liner has not been welded to the required shape. Rubber liners are unquestionably the best, but both PVC and LDPE can be used to good effect. Secure the liner either by trapping it beneath the uppermost timbers, or by nailing narrow wooden laths around the top, just above the proposed water level.




1. Mark out the area of the pond with pegs and excavate a foundation for the retaining wall about 10cm (4in) deep and 10cm larger all round than the external dimensions of the pond.

2. Place some crushed hardcore into the base of the foundation trench. Finish off with a level layer of concrete of the same mix as that used for a concrete pond set in the ground.

3. Build up the walls starting from a corner and use a traditional English bond. The wall must be both level and upright. Check levels regularly with a spirit-level.

4. To prevent liner damage from abrasive brickwork, secure fleece, geotextile matting or polystyrene sheets to the surface of the brickwork, using an industrial adhesive..

5. Install the liner, taking care to fit it neatly to the corners. A welded rubber liner is the best option. Turn the liner over the top edge of the brickwork so that it can be secured.

6. Finish the top of the wall with coping stones, or with a final row of bricks, bedded on mortar. The top edge of the liner will be trapped beneath this, just above the proposed water level.

5- wood containers  Ponds

Ponds don’t necessarily have to be in the ground. By adopting some of the techniques and materials used in the wood foundation industry, you can build a pond above ground a whole lot faster and easier. An above-ground design may be safer, too, but always supervise small children around any type of pond.


Raised garden ponds can be placed on any surface and, because they are raised, require no excavation with no excess soil. Choose the area for the pond before assembling as they can be quite heavy and difficult to move once assembled. 


It can be a very practical solution for the limited spaces like balconies or patios
