Benefits of building a raised pond
There are many benefits to building raised ponds compared to in-ground ponds.
Raised ponds are safer than in-ground ponds
Compared to in-ground ponds, a raised pond can be safer due to the elevated design. A raised pond is ideal if you have children or pets who like to run around and explore the garden. The raised nature of the pond means you do not have to worry about anyone accidently falling in.
A raised pond for your outdoor living space can also protect your pond inhabitants from the harm of other wildlife. Raised ponds can also prevent your children from interfering with the fish and plants in your pond.
Raised ponds are easy to manage
Raised ponds are easy to manage for an array of reasons; Initially because they do not require digging up the existing soil in order to implement them. Secondly, they offer easier access and visibility to rectify any issues if need be unlike in-ground ponds. Thirdly, cleaning the pond, feeding the aquatic life and checking the health of the inhabitants is much easier in a raised pond, particularly if you suffer from any accessibility issues.
Planning Your Raised Pond
A pond is a great way to enhance your living environment and requires planning for it to blend seamlessly in your garden or outdoor space.
Firstly, decide whether you are going to use timber, concrete blocks, or brick to build your pond and then come up with the detailed design including size and shape.
The easiest way to build a raised pond is with railway sleepers because it holds back the water pressure when it is joined with sealant. Therefore, decide if you are going to build a square or rectangular shape. Railway sleepers typically come in L-shaped sizes of 6″x3″ and you can create a 6″x6″ pond with them.
Brick or concrete block raised ponds provide the best strength and longevity, and therefore are optimal for a koi pond. Aesthetically, brick, railway sleepers and concrete will give you more of a rustic look whereas wooden ponds will create more of a contemporary look for your garden.
Materials and Tools Needed to Build a Raised Pond
The tools needed for building a pond will depend heavily on whether you’re building your pond from timber, concrete blocks, or brick so bare that in mind when ensuring you have everything you need.
For installing raised garden ponds you will need the following:
- Pond liners
- Measuring tape
- Spirit level
- Water filter and pump
Step-by-Step Construction Guide on how to Build a Raised Pond
Determining where to start when figuring out how to build a raised pond can be daunting. Here are step by step instructions to build a perfect pond.
Choose a location for your pond
You should consider the placement of your pond before building it. Ideally your pond should be in an area where it is visible and accessible. For example, a good place to put your pond would be within an outdoor seating area, like a patio or cabana in your garden. Also keep in mind that it should be close to a power point for the filtration system, or if this is not an option then decide how you will bring a power to the area where you are planning to install the pond.
Ensure the ground is level
Your garden pond installation should be in a location where the ground is even to ensure the water does not overflow on one end or side. It should also be protected from sharp objects that can puncture the lining and compromise its watertight nature, including stones, tree roots or any other hazardous items.
To check if the ground is even you can put a piece of wood on the area and place your spirit level on top. If it is not flat you can even out the surface with a shovel, but this is the most digging you’ll have to do which is a lot less labour intensive than compared to building an in-ground pond.
Build the pond frame
If you are building your pond frame with railway sleepers you should first set down the sleepers in your desired shape ensuring that each corner has right angles. Then, fasten the railway sleepers together with 90-degree angle brackets.
Once the first layer is complete and secure, continue to add layers of sleepers until you reach the penultimate layer in terms of your desired height of the pond.
Ensure that the sleepers are evenly stacked for sturdiness and that there aren’t any screws or sharp edges sticking out that could puncture the liner.
You can then add the pond underlay followed by the pond liner, measured with a little overlap, to prevent water from seeping through the pond or fish waste and sediment from pervading it. Next, you can add the final layer of sleepers on top of the excess liner to secure the pond liner, then trim the visible excess liner on the outside edges. You can also use timber capping for the top for a cleaner look.
The construction guide for building a pond with railway sleepers is similar to building a raised timber pond, or wood or decking. Measure the timber, wood, or decking strips from one corner to the other and cut it to your desired size, then use nails to connect the strips.
However, to secure your timber or decking pond you will need corner posts of the same height to withstand the weight of the water and provide extra support to your pond.
Fill the pond with water
This is the best step because you get to witness your pond come to life. Ensure that the water level does not reach past the point of the final layer of your sleepers or your timber capping where the liner overlaps when you fill it with water.
Finishing Touches and Maintaining a Raised Pond
Garden ponds and fish ponds are very popular at the moment. You can add fish or plants to your pond to give it more life. However, ensure that the species of fish and/or plants are compatible with each other so that they are able to thrive.
For a garden pond or wildlife pond you should add 6-8 inches of low nutrient clay soil at the surface of the pond to make it easier for your plants to grow. Ensure that the tall plants are planted at the back of the pond and the shorter plants in the front,
For fish ponds or a koi pond, you should install a water filtration system to ensure that the water quality is optimal for a healthy living environment that they can thrive in. The pond filter and pump will also ensure that all the fish waste is taken care of so ensure you purchase the correct pump type depending on the size and depth of your pond.
You should check the water quality and filters from time to time to ensure that the fish are well taken care of.
