Steel ties and tongue & groove joints provide very rigid ICF forms that are easy to concrete.
Build it Fast!
Do not wait 3 or 4 months for a timber frame or bricklayers – the roof is on in weeks with ICF
Made in UK
Large stocks and UK manufacture ensures reliable delivery across the UK.
Why ICF.
What makes ICF Insulated Concrete Formwork better than traditional construction methods?
PolyBlok ICF is designed to form insulated, fireproof, sound resistant, draughtproof, indestructible walls that are very fast and easy to build and last a lifetime.

ICF Design & Installation
Why PolySteel.
The rigidity of our ICF forms, their simple installation and no need for complicated propping systems is why PolyBloks make ICF simple.
ICF Made Simple.
PolyBloks are delivered ready made and don’t require assembly unlike some other ICF forms which require complex kits and spare parts. The steel ties, precision tongue & groove jointing system and high tensile wire clips ensure simple and trouble free installation and concreting.

Reinforcement.
Polysteel Forms are certified for the use of plain concrete, therefore reinforcement is not required to build a normal house. When reinforcement is necessary, the rigidity of these insulated concrete forms makes them uniquely suitable for concrete compaction using a vibratory poker to remove any risk of voids being left that will allow corrosion of the steel bars.

Better than traditional methods.
Traditional construction such as timber frame and cavity walls have significant disadvantages. These are easily overcome or completely avoidable when insulated cement forms are used.
ICF Design.
Most architects and engineers are still unfamiliar on how to fully utilise the benefits of Insulated Concrete Formwork in project planning. The complexity of some ICF systems only makes this more difficult. Our ICF design services make full use of the advantages and ensure builders have all necessary information to quickly build and finish their projects.

ICF Projects.
RESIDENTIAL
Residential Buildings
ICF Insulated Concrete Formwork is ideal for novice & experienced builders. Buildings can be waterproofed within weeks, entire streets can be erected quickly and all ensuing trade visits completed sometimes in a single visit.
COMMERCIAL & AGRICULTURAL
Commercial, Industrial & Agricultural
ICF is ideal for the rapid construction of very economic buildings. In many instances the steel columns and their expensive foundations can be omitted and replaced with a few reinforcing bars in the insulated concrete form walls.
BASEMENTS & POOLS
Basements & Pools
Insulated cement forms are ideal for the design and construction of basements and basement swimming pools. The walls are easy to waterproof, quick to construct and do not need a team of highly skilled/costly tradesmen.
RETAINING WALLS & SMALL STRUCTURES
Retaining Walls & Garden Buildings
Insulated concrete form walls are ideal for the self-builder to construct garden offices, sound studios, garages, indoor swimming pools and retaining walls without the need for expensive bricklayers and carpenters
Why choose ICF?
Polysteel’s unique ICF system is simple and easy to use for any building project.
