FLEXIARCH
FlexiArch is a patented precast concrete arch bridge system that combines the efficiency of modern construction with the durability of traditional masonry arches.
Engineered for speed, strength, and sustainability, FlexiArch offers a cost-effective and low-maintenance solution for a wide range of bridge projects.
What is FlexiArch?
FlexiArch is a modular precast concrete bridge system designed to replicate the performance of traditional stone arch bridges while providing all the benefits of modern precast methods. It is ideal for road bridges, pedestrian crossings, railway structures, and sustainable infrastructure projects.
How does FlexiArch work?
The system is built from precast concrete voussoirs (tapered blocks), each manufactured with the correct taper for the required span and rise. These blocks are linked with a flexible polymeric membrane, allowing the arch to naturally form into its correct load-bearing shape when lifted into place by crane.
How is FlexiArch delivered to site?
A FlexiArch bridge is delivered flat-packed on flatbed transporters, making it easy to transport and handle. Each delivery includes:
- Precast flexible arch rings for the required bridge width
- Precast spandrels, which can feature decorative finishes
The spandrels form the external face of the bridge and act as permanent shuttering for the concrete infill. While they do not carry traffic loads, they provide durability and aesthetic appeal.
Why is FlexiArch a sustainable bridge solution?
FlexiArch is designed for long-term sustainability:
- No steel reinforcement is required
- 100% compression structure – self-supporting without mortar
- No risk of steel corrosion, expansion, or concrete cracking/spalling
This results in a low-maintenance bridge with a long service life, reducing whole-life costs and environmental impact.
