Post Tensioned Stone Staircases
Engineering Elegance
Post-tensioned staircases represent the most technically advanced form of structural stone. Using precision engineering, each tread is drilled to accommodate steel tendons which are tensioned after installation. This process places the stone permanently into compression, creating a staircase that is both structurally robust and visually striking. The result is a free-standing stone stair that appears to float, combining architectural ambition with proven engineering.

Design and Technical Considerations
There are a series of other important technical aspects and details which are all carefully considered and solved by design including: steel tendon geometry & curvature; tread interlock details; attachment bracketry; stressing and grouting specialists; load testing; temporary build frame.
Our Approach
Why AF Jones
We bring together centuries of stone craftsmanship with modern engineering expertise. Our experience in delivering both cantilevered and post-tensioned stone staircases sets us apart. By combining traditional skills with advanced technology, we can offer clients staircases that are both structurally assured and architecturally exceptional.
Next Steps
If you are considering a post-tensioned stone staircase, we recommend early consultation. Our team can provide guidance on design options, feasibility, and cost, as well as prepare workshop mock-ups to give certainty before site installation. Contact us to discuss your project or arrange a visit to view a mock-up in progress.
