Water walls are amazing water features. Their gentle flow can be extremely soothing while adding a great deal of style to your garden. However, there are common mistakes in the installation process that can turn your soothing water wall into a massive headache. Here are four mistakes that are easy to avoid with a bit of forethought and planning. For more advice on avoiding these mistakes and others, talk to your local water features supplier.
Installing the Wrong Water Wall Type
There are two types of water walls. Sheet descent water wall troughs have water that flows over a lip or spout and down the surface of the wall into a catchment. Projecting water walls send the water out in an arc, falling up to 20cm away from the wall, to be caught in a pond. One of the most common water wall mistakes is installing the wrong type of wall. Sheet descent and projecting water walls have very different effects. Sheet descents are quieter with a subtle look and projecting water walls create more sound as the water splashes down into the pond and have a more dramatic look. You’ll be much happier with your water wall if you know what effect you want beforehand.
Incorrect Trough Installation
The trough is a crucial part of your water wall. It is where the water flows from to form the sheet of water. If the trough isn’t installed correctly, the sheet of water doesn’t form properly. The trough needs to be completely level to create an even flow of water. It also needs to be the correct level make sure it isn’t too high. Sheet descent water walls should be at most 2 metres over the pond or catchment, and projecting water walls should only be 1.2 metres high. Installing the trough above those heights will lead to an uneven flow of water and a loss of the sheet effect you are looking for.
Wrong Size Pond or Catchment
The pond or catchment is what the water falls into at the base of the water wall. A pump in the catchment sends the water back up to the trough to cycle through the water wall again. Your pond needs to be large enough to catch all the water from the water wall including the splash. Otherwise, you’ll be constantly losing water. A supplier can tell you the smallest size pond or catchment that will work for you.
Water is constantly running down the surface of your water wall. This makes it crucial for your wall to be properly waterproofed because if it isn’t, water will find a way past your cladding. You’ll then be dealing with rot, warping and other damage. Use a high quality waterproofing membrane to protect your wall.
