Precast Concrete Advantages
The Advantages of Precast Concrete Stairs
Efficient. Elegant. Engineered to perfection.
Precast concrete staircases offer a smarter, faster, and more cost-effective alternative to in-situ poured concrete, all without compromising on quality or design. Whether you’re working on a bespoke home or a large-scale development, Kallisto’s precast stair solutions bring both aesthetic appeal and practical benefits to every project.
How Much Do Precast Concrete Stairs Cost?
Thanks to the efficiencies of a controlled factory environment, our precast concrete stairs are more affordable than in-situ concrete alternatives. The repeatable use of flexible steel moulds, combined with off-site precision manufacturing, reduces labour costs and eliminates on-site delays, delivering cost certainty and value.
How Long Do They Take to Install?
Our curved and helical staircases are typically installed within a single day, and often alongside the structural flooring. By contrast, in-situ stairs can take weeks to construct, cast, cure, strip, and finish. With precast, you accelerate the programme and reduce on-site disruption.
Are They Safe and Secure?
Absolutely. Kallisto stairs are designed to provide an immediate working platform upon installation, enabling safe access for follow-on trades without the need for alternative scaffolding or temporary solutions. In comparison, in-situ stairs require extended curing times and cannot be safely accessed during construction.
How Does Quality Compare to In-Situ?
Precast stairs are manufactured using precision moulds in a quality-controlled environment. This ensures consistent finishes, dimensional accuracy, and reduced waste. In-situ stairs, by nature, depend heavily on site conditions, which can introduce variability and weather-related delays. Our system also allows for formwork reuse, reducing environmental impact compared to single-use shuttering.
Construction Benefits at a Glance
Precast concrete staircases offer a host of construction advantages over in-situ poured methods:
Efficiency
Rapid installation, tailored to your specification. Precast accelerates your programme and minimises time on site.
Health & Safety
Once installed, our staircases provide immediate access for site operatives and can be used safely with temporary handrails in place.
Fire Resistance
All Kallisto precast stairs are inherently fire resistant, meeting high standards for safety and compliance.
Consistent Quality
Each stair is cast off-site in a clean, weatherproof facility — avoiding delays and defects caused by variable site conditions.
Cost Savings
Avoid costly and time-consuming on-site pouring. Precast offers a cleaner, leaner and more predictable construction process.
Design Flexibility
Suitable for steel-framed or concrete structures, our stairs can be tied directly into your floors using projecting reinforcement, allowing seamless integration into your build.
Precast Stair Design Meets Performance
Combining the versatility of concrete with advanced engineering and superior finishing techniques, Kallisto stairs are both beautiful and built to last. Our palletised formwork and shuttering systems, developed using leading Northern European technology, ensure a high-quality finish, every time.
Whether you’re specifying a curved, spiral, helical or cantilever staircase, our precast system allows you to realise even the most ambitious architectural designs without compromise.
