Liner Pools – The Pros and Cons Explored

At Compass Pool whilst we don’t install liner pools we have dealt with many in the past so we explore the pros and cons of this swimming pool construction method. 

What is a liner Pool?

A liner pool is essentially a swimming pool that uses a plastic or PVC liner in order for it to hold water. This opposed a concrete tiled pool or ceramic composite pool that uses either the concrete or composite material to ensure it is water tight. They can either be inground or above ground. The substructure of the pool is made of lots of different material explained below in how a liner pool is built. 

How to build a liner Pool

The pool construction of a liner pool can take many forms. The first and simplest – a concrete block shell is constructed from hollow concrete blocks that are then filled with concrete, or alternately the stepoc block. This is then rendered ready to accept the liner which has a felt backing between the pool and the liner.  Other forms of liner pool construction include insulated hi fibre plastic panels that are interlocked together or steel panel of a similar construction. All of these have their pros and cons when it comes to longevity, simplicity of installation and running costs.  Sometimes wood frames similar to a log cabin construction are used and installed in the ground although their lifespan is limited to 10 years.  The floor of a liner pool will typically be a non-structural screeded base straight onto the dirt. Depending on the wall construction they are reliant on the water pressure inside balancing the ground pressure outside so should not be emptied without an expert and ground water can cause “liner bulge”

The history of a liner pools

Liner pool origins in the UK date back to the early 1960’s as plastics technology started to improve and the vinyl liner was born. Marley Tiles who developed the lino floor tile in the UK first started a prototype above ground pool made of a similar material to their floor tiles.

How much does a liner pool cost?

The cost of a liner pool will range hugely depending on the substructure construction the access to your garden and cost of excavation. Typical costs from £20k for a self-build dig to in excess of £60k for a fully managed project. 

Why choose a liner Pool?

If you are on a budget that won’t stretch to a composite or tiled pool a liner pool is the answer. You should budget for the long-term costs of a liner replacement as this will typically last between 5-10 years.
