Standard Formwork Solutions

KORE - EPS Arch Formers

Arch Formers

KORE Arch Formers provide temporary support to curved masonry structures until the structure is able to support itself. Arch formers are made from EPS, lightweight and can be reused where identical elements are needed.

KORE Spiral Staircase Formers

Spiral Staircase Formers

KORE EPS can be used for spiral staircase applications where complex designs require formwork. KORE Spiral Staircase Formers are customised to your exact project requirements and can be reused (i.e. between flights of stairs).

KORE Column Formers

Column Formers

KORE Column Formers are perfect for projects that require custom in-situ reinforced concrete columns. Made from KORE EPS, KORE Column Formers are reusable, allow for high quality exposed concrete finishes and manufactured to your exact specification.

Formwork for Ribbed Concrete Floors

KORE EPD Trough Moulds

Trough Moulds

KORE Trough Moulds are the perfect solution for constructing ribbed concrete floors with one-way spanning. KORE Trough Moulds reduce concrete requirements, can achieve longer spans than traditional flat slabs, are lightweight, reusable and are manufactured to exact specification.

KORE EPS Waffle Moulds

Waffle Moulds

KORE Waffle Moulds are the perfect solution for constructing two-way spanning ribbed concrete floors. Offering reduced concrete volumes and the ability to achieve greater spans, KORE Waffle Mould are lightweight, reusable and built to exact specifications.

Piling Solutions

KORE EPS Guide Wall Formers

Guide Wall Formers

KORE’s EPS Guide Wall Formers are used to form an in-situ, sacrificial guide wall to improve the accuracy of pile guide wall construction. Sacrificial guide wall formers are for single use in many civil engineering and construction applications.

Secant Pile Wall Construction

Secant Pile Wall Construction

KORE EPS can be utilised for secant pile wall construction (i.e constructing intersecting reinforced concrete piles). Secant piles are reinforced with steel rebar or steel beams and provide a number of benefits, including an increase in construction alignment flexibility and wall stiffness when compared to other solutions like sheet piles.

Temporary Access & Safety Solutions

KORE EPS - Temporary Access Ramp

Temporary Ramps

KORE EPS easily creates temporary ramps when access to floors of differing heights is required. KORE’s temporary ramp solutions are bespoke and manufactured to exact specifications, easy to install, lightweight and can be repositioned and reused as necessary.

KORE EPS Rail Platform Crossings

Rail Platforms

KORE’s EPS rail platforms allow for safe and easy crossing between platforms. Available in different grades of EPS, our bespoke rail platforms can easily accommodate varying loading requirements.


KORE EPS For Road Embankment

Road Embankments

KORE EPS can easily be used as a light fill material in road embankment applications. KORE EPS for embankment applications helps with both stability and and settlement issues with soft subsoil conditions and offers a reduction in load on the subsoil and settlement.

KORE EPS for Slope Stabilisation

Slope Stabilisation

KORE EPS provides slope stabilisation as a soil substitute fill to reduce driving forces. KORE Expanded Polystyrene does not degrade or absorb moisture, making in the ideal solution for slope stabilisation applications.

Additional Void Former Applications

KORE EPS for Marine Pontoons

EPS for Marine Pontoons

KORE EPS works exceptionally well for marine pontoon applications due to its buoyancy and water resistance. KORE EPS can be used for a variety of floating structures including docks, rafts, floating shelters, pontoons and slipways.

KORE EPS for J Feed Trough

J Feed Troughs

KORE EPS can be used to form concrete J feed troughs and other troughs that need to be durable, weather-resistant and strong.
