Concrete Foam
Construction foam blocks (also known as polystyrene void formers) are an integral component in construction and civil engineering applications. Isolite – Polystyrene void formers are lightweight, rigid foam profiles or blocks cut to size made from expanded polystyrene (EPS) resulting in a material that is both durable and lightweight.
Applications for Using Concrete Construction Foam Blocks
The void formers are used in concrete construction to create gaps or voids within structures. Construction foam is often necessary in concrete to form a void or space for utilities or services such as pipework junctions within a manhole or block-outs in a concrete mould. The use of construction foam blocks or block-outs in precast concrete applications allow for faster turn-around times, the length or shape of an existing mould can be quickly adjusted reducing overall fabrication cost and increasing productivity.
Building Foundations
In foundation construction, construction foam blocks are used to create space for utilities or to reduce the weight of the foundation.
Floor and coffered slabs
In commercial buildings or parking structures, void formers can reduce the amount of concrete needed while maintaining structural integrity. This is particularly beneficial in high-rise buildings where weight considerations are crucial.
Retaining Walls
In retaining wall construction, sacrificial void formers can be used to create cavities within the retaining wall construction when removed, providing the opening or cavity required for drainage. Void infill blocks can be used to stabilise soils that reduce the load enhancing the stability and longevity of the retaining system.
Bridge Decks
(EPS), Void Formers provide significant benefits in terms of weight reduction, cost efficiency, and structural integrity. Engineers can optimise and enhance the performance and cost-efficiency of concrete bridge structures using Foam Tech Iso-lite foam profiles that are cast in-situ, resulting in less concrete being required. The reduction in weight decreases the load on supporting structures and foundations leading to improved overall stability and reduced structural demands.
Benefits of Using Construction Foam Blocks –
Weight Reduction
One of the primary advantages of using Polystyrene void formers is the reduction in the overall weight of the concrete structure. By creating voids, the weight of the concrete slab is significantly reduced. This reduction can decrease the load on supporting beams and foundations, leading to cost savings in structural supports and materials.
Cost Efficiency
The use of Polystyrene EPS foam can lead to substantial savings in large-scale construction projects by reducing the amount of concrete required for a project.
Improved Thermal Insulation
Polystyrene has excellent insulating properties. When EPS void formers are used in construction to insulate a concrete slab they can contribute to increasing the energy efficiency within the structure. This enhances the overall thermal performance reducing heating and cooling costs over the lifespan of the building.
Ease of Handling
Construction foam blocks or void formers are lightweight and easy to handle, which simplifies the construction process. They are easy to cut and shape on-site, allowing for quick adjustments and installation.
Environmental Benefits
By using Polystyrene void formers, construction projects can become more environmentally friendly. Reduced concrete usage lowers the carbon footprint associated with cement production, and the insulation properties of EPS can contribute to energy savings.
Construction Foam Blocks in Perth
Construction foam blocks offer a range of benefits that make them a valuable tool in modern construction. From reducing weight and construction costs to enhancing thermal insulation, these innovative materials contribute to more efficient and sustainable building practices. Whether used in foundations, floor slabs, retaining walls, or bridge decks, construction foam plays a crucial role in optimising concrete structures and improving the overall quality of construction projects. As the industry continues to seek out more cost-effective and environmentally friendly solutions, EPS construction is poised to remain an essential component in the future of the building industry.
