KORE EPS Void Formers

KORE’s EPS Void Formers are used extensively throughout the construction industry for major works such as motorways, underpasses, shopping centres, foundations and embankments. KORE Void Formers are suitable for domestic and commercial applications.

KORE EPS can be used as both void formers and void fillers. Void formers decrease the volume of concrete, reducing weight while increasing the strength of concrete. Void fillers are designed to fill a void with Expanded Polystyrene and are left in-situ.

KORE EPS Void Formers and Void Fillers are available in a range of compressive strengths to suit the needs of the project.

PERFECT FOR CIVIL ENGINEERING

KORE’s EPS Void Formers are perfect for civil engineering applications, such as motorways, underpasses, foundations and embankments.

MINIMISE THE WEIGHT OF CONCRETE

KORE Void Formers reduce the weight and enhance the strength of concrete and are available in a range of compressive strengths to suit the needs of your project.

EASY TO WORK WITH AND INSTALL

KORE Void Formers are manufactured to your exact project requirements and are easy to work with and install. KORE’s EPS Void Formers can be cut on-site without the need for specialised equipment.

RESISTANT TO WATER AND MOISTURE

Like all EPS products, KORE Void Formers and water and moisture resistant and will not absorb or retain moisture. KORE Void Formers are suitable for nearly all ground conditions.

WHY CHOOSE KORE VOid formers?

KORE Void Formers are the ideal solutions for applications that require the reduced weight of concrete when left in-situ. KORE Void Formers can also be used temporarily as part of a formwork system.

KORE Void Formers are made from Expanded Polystyrene – the same high performance material used for our extensive range of insulation solutions. Made from 98% air, KORE EPS is lightweight, versatile, water and moisture resistant, rot-proof and will not degrade over time.

KORE Void Formers are manufactured to the specifications required from each project and profiled before delivery to site. KORE Void Formers can also be cut on site without the need for any specialised equipment. KORE EPS can be used for both void former and void fill applications.

Applications for KORE Void Formers

Standard Formwork Solutions

KORE Arch Formers - Void Formers made from EPS

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.

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).

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 EPS for 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.

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

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

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

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.

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.

Embankments

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.

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 EPS Applications

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 Troughs

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.

Applications for KORE Void Formers

KORE Expanded Polystyrene void formers are used during the formation of foundations. EPS is the ideal solution as it will not absorb water. This ensures the adjacent concrete quality is unaffected. Our EPS blocks can be cut to suit individual site conditions.

KORE Void Formers are extensively used to reduce the dead-weight of a variety of structures, including pre-cast flooring beams and motorway bridges. By reducing the lateral forces, a simpler foundation design is possible.
KORE manufacture and supply trough and waffle moulds. These form the foundation of in-situ reinforced concrete ribbed floors. These moulds are both versatile and cost effective in their design.
KORE Void Formers are used during road embankment to reduce pressure on soil and are a cost effective solution for piled construction when traditional embankments are too heavy. The lightweight properties of EPS will provide the required load bearing foundations without causing settlement.
