Waterfall Pond Liners

Including a stream or waterfall in your pond can have a great impact on its overall look and appeal, but it’s crucial to ensure you install the correct waterfall pond liner.

A waterfall or stream can also help keep the water aerated, reducing the likelihood of bacterial growth and providing oxygen for fish and plant life. Waterfalls and streams can take any number of shapes and designs, and can be very simple to install following just a few simple steps. Your waterfall or water feature can be constructed in a variety of ways, either using the natural ground where the pond is situated, or using a purpose built arrangement of rocks or brickwork.

Stephens Liners recommend and use aquaSHIELD Protective Matting for Waterfalls and Streams:

Waterfall Liners - Protective Matting


aquaSHIELD Protective Matting is used in conjunction with the waterfall liner to protect it against sharp rock edges and perforating the liner whilst in use.



The following examples make use of purpose built arrangements, but the steps to be used are the same in almost all situations when building water features.

Step 1: Protective Matting Installation

Once the shape for the waterfall or stream has been decided on, it is essential that a layer of aquaSHIELD Protective Matting is fitted under waterfall liners to ensure that the liner is protected against rocks or other sharp objects. This helps to avoid punctures and leaks in a waterfall pond liners, particularly due to moving water causing abrasion.

Step 2: Liner Installation

Where a waterfall or stream feeds into a pond extra care should be taken to prevent leaks when fitting.

We recommend that streams should be lined with the same material as the pond where possible.
In the case of waterfalls the cascading water should overhang the main pond liner sufficiently so that water cannot get behind the waterfall liner and cause damage or flooding.

Step 3: Joining the Liner

Rather than simply overlapping the waterfall liner into the pond, it is recommended that the waterfall liners are joined with appropriate tapes and adhesives, as shown below.

Step 4: Decorative Finishing

Where a decorative finish is required such as the use of stones or specialist precast waterfall products, an additional layer of protective matting or lining material must be placed on top of the liner to ensure the liner does not become damaged and torn. People sometimes mistakenly overlook this, but is a costly mistake and we always recommend adding this protection.
