Introducing TechSpan® Precast Concrete Arch Systems
Geoquest USA offers a high-quality selection of TechSpan® precast concrete arches. This series was designed for ease of installation by minimizing heavy equipment use and bracing requirements without sacrificing the enhanced beauty and durability of optimized shaping.
Applications of TechSpan Precast Arches include:
- Short to medium span bridges
- Tunnels for roadway, railway, pedestrian, and mining site reclaim or access
- Culverts
- Ammunition storage facilities
- Above-ground earth shelters
Our Installation Process
TechSpan solutions feature half-arch units in a three-hinged precast system, allowing them to work in tandem with MSE walls. Geoquest USA’s straightforward installation process involves:
- Design: Geoquest USA engineers collaborate with your decision-makers prior to construction to establish a clear goal and a path forward. We use your specifications and aesthetic notes to create a cohesive, efficient plan designed to help you foster success.
- Footing placement: We use cast-in-place or precast footings as the foundation for your arch. After we place the first three units, the structure becomes self-supporting, which simplifies the installation process.
- MSE installation: Mechanically stabilized earth (MSE) walls add tremendous support for arches, facilitating lasting durability and strength.
Benefits of TechSpan Precast Concrete Arches:
- The finite element design provides for the development of the optimal shape based on loading conditions.
- Precast segmental arch units simplify shipping, delivery and installation.
- The self-supporting unit design and installation procedure minimizes heavy equipment usage and bracing requirements.
- Precast units are manufactured under strict quality control environments and tolerances to insure ease of installation.
- They are capable of supporting large surcharges in excess of 100 feet.
