Why We Build Swimming Pools With Reinforced Concrete

Not all Pool structures
are created equal.

ClipBlox combines steel reinforcement and concrete to create a 150mm monolithic reinforced-concrete pool structure — with lightweight permanent formwork that makes it faster and easier to build.

A POOL IS A STRUCTURE

A swimming pool isn't a bath, it's a water retaining structure

A pool holds tens of tonnes of water, it has to withstand constant pressure from the inside, earth and groundwater outside, temperature changes and the loads from the surrounding landscaping, terraces and buildings. 

​

They're exactly the engineering problems reinforced concrete is designed to solve.

Steel Reinforcement

Untitled design (23).png

Provides tensile strength and mitigates cracking

Steel reinforcement works with the concrete to create a strong, stable structure, helping the pool shell resist movement and control cracking over the long term.

Structural Concrete

Untitled design (17).png

Creates the mass and compressive strength

Concrete surrounds the steel reinforcement to create a solid, stable structure capable of resisting the forces acting on the pool shell.

Monolithic Construction

Untitled design (22).png

Turns reinforcement and concrete into one structure

The concrete and steel work together throughout the shell, creating a continuous structure designed to act as one.

We're not adapting a product to behave like a pool structure.

CLIPBLOX POOL SHELL

A Monolithic Structure. Built for the Long Term.

Clipblox creates a 150mm reinforced

concrete wall with permanent

lightweight formwork. The result is a

strong durable and flexible pool 

structure built on site.

Monolithic concrete pool shell

Faster and easier to build

Design freedom shape and size

Simple logistics

Wide choice of finishes

Long term sustainable solution

SPRAYED SHELLS

A concrete shell, sprayed
to different shapes

Sprayed concrete pools are formed by applying concrete over steel reinforcement. They can be extremely strong structures, but they require specialist equipment and experienced application.

Only as good as the application

More prone to surface variations

Requires a lot of timber

A lot of joins in the concrete

Needs to be rendered

Can be a messy job on site

TRADITIONAL BLOCKWORK

More Labour. More Materials. Slower to Build.

Traditional pool construction

involves laying hundreds of individual

masonry blocks and mortar joints

to create the walls.

Labour intensive

Many joints 

Slower construction

Higher risk of cracking

Hard work. Lots of labour.

Needs rendering

ONE PIECE POOLS

Designed for the lorry
Not your garden

One-piece pools are manufactured

in a factory and must be transported

to site and lifted into position, which

can limit access and design options.

​

Requires road access and crane

Restricted to set sizes and shapes

Difficult or impossible on many sites

Limited design flexibility

Finish limited to the factory shell

Classed as a rigid liner

ICF POOLS

Concrete Strength.
With a foam sandwich

ICF systems also rely on a 

reinforced-concrete core, with

permanent layers of EPS insulation

on both sides of the concrete

Thick layers of EPS insulation

Higher Material cost

Finishing options difficult

More complex detailing

Environmental impact of EPS

Not guaranteed against bursting

PANEL POOLS

A Collection of Panels Not a Monolithic Structure.

Panel pools use prefabricated wall

panels joined together. The structure

relies on mechanical connections

and a separate waterproof finish system.

​

Multiple panel joints

Design limited by panel sizes

Liner finish only

Timber doesn't last forever

Not suitable in all ground

Can't always be emptied
