Pond Liner FAQs

What are your pond liners made from?

Flexiliner Pond Liner Material and Construction
Flexiliner pond liners are manufactured out of LDPE (Low Density Polyethylene). An ultra-tight weave of tough fibres is sandwiched between two layers of rot/UV resistant laminated coating. This means that the pond liners are tough and strong, yet still supple and flexible enough to easily move into position when pond building.

Are your Pond Liners as good as other types?

Flexiliner (LDPE) Pond Liners vs Butyl or PVC Pond Liners
There are a lot of pond liner materials on the market and we have tried them all. But listening to landscapers we know that one real advantage of our Flexiliner is that they are reinforced. The more uniform material of the other pond liners means that a tiny puncture or tear can run when the weight of water is introduced to the pond. This does not happen with our liners as the inner weave acts as a reinforcement grid within the pond liner. Try cutting a sample with a pair of scissors and then try to tear it apart with your hands and you will see what we mean! You can be reassured by the fact that our pond liners are now employed successfully in thousands of pond installations across the world. Each one backed by us with a long-life guarantee.

How can you offer such low pond liner prices?

Remarkably Low Price Pond Liners
The clever construction method we employ means that a pond liner made out of a less expensive base material can last for just as long as other, more expensive pond liners. Plus, due to our success we can manufacture vast bulk quantities of these pond liners and this too helps to keep production costs low. We pride ourselves in offering the lowest liner price in the UK and fight to keep this position. Despite a raw material increase this year we have not raised our prices and will continue to offer the best price possible.

Why do I need a pond liner/ What choices are there?

Pond Lining – The traditional approach
People have been creating water gardens for hundreds of years. Vast water expanses and lakes were created for the great country estates in 18th Century Britain by the likes of famous landscape gardeners such as Capability Brown. Then, as now, thought had to be given to the question of lining the pond so that the water couldn’t escape. Traditionally water was retained by puddling pools in clay before they were filled. This method is rarely used today as it’s a messy and time-consuming task and clay ponds can be subject to cracking during drought.

The modern water gardener has much more choice:

  • Flexible pond liners
    If you’re after more than 4 square metres of surface water and a choice of depth then flexible pond liners are the answer. The types available are typically Butyl pond liners, PVC pond liners and LDPE Pond Liners. All modern flexible pond liners will give good long lasting results. The LDPE pond liners manufactured for have the benefit of being reinforced – this means that any tiny punctures created by rogue thorns/stones will not stretch and rip through the pond liners when the weight of water is introduced.
  • Concrete pond lining
    There is the possibility of manufacturing the pond liner out of concrete and this method does create a very good long-lasting barrier. However, there is a lot of on-site mess and disruption and it is an expensive option.
  • Rigid pond liners
    Rigid pre-formed pools made out of plastic (typically HDPE) can be used as pond lining for smaller projects. However as they are molded into a pre-selected shape and size they are only worth considering if they match the dimensions of the project that you have in mind..

PondXpert Solar Shower 150 Pond Pump


Rubbish. Only works in full sun and therefore not much use in NW England. When it does work it's like spitting in the wind and the flow is useless. Also very flimsy. Would not recommend for any size water feature.

Great value if a little noisy

PondXpert Blanket Weed Brush Set (PX0NETBWBRUSHSET)


This blanket weed brush is very good at picking up the blanket weed without disturbing the rest of the pond. The only problem is then removing the weed from the brush. This is why 4 stars and not 5. I am pleased with this brush but wish I could work out an efficient way to remove the weed from the brush.

PondXpert SolarAir 200 Solar Air Pump


Solar aerator does what it says. In UK in April the panel needs to be oriented towards the sun in order to perform but otherwise its doing the job as expected

PondXpert Solar Shower 150 Pond Pump


Purchased this as a beginner to supplement a small water feature in the garden. It does require a good bit of sunlight to work properly which I expected after reading other reviews. The adjuster didn't seem to make much difference to the flow so I put an extra couple of holes in the head to prevent losing too much water as I was only using a small pot. Would be really nice in a little pond so good value overall.

  • Customer also bought: .... :
  • Basic Underlay 4x4

4m x 4m liner had a join in it. Disappointing as it is only small and not what I expected for such a small piece

Basic Underlay 4x4

  • Customer also bought: .... :
  • 15yr pondliner 4x4

I ordered 4m x 4m underlay. The underlay I received was 2m x 8m so I had to cut it and overlap it. Turned out Ok but this is not what I ordered or was told I would get.

PondXpert Blanketweed Eliminator


Early days, have tried 2 applications. It seems to have made a difference but I will persevere and try some more.
