The proven strength and performance characteristics of precast concrete portal frames and UAN culverts, together with their excellent service life, make them ideal for a wide variety of civil engineering and construction applications.
UAN Culverts:
UAN culverts consist of two U-shaped sections, which can then be assembled on-site. A ball and socket joint is used between the two parts of the finished section. This option can be offered for larger culverts that are unsuitable for transport as a monolithic structure or if there are any site specific weight constraints.
The popularity of UAN culverts is growing, this is largely down to their immediate stability, quick installation, and the flexibility in being able to manufacture culverts for a wider range of applications.
Key uses include as an underbridge for road or rail, and in other road infrastructure projects.
- Adjustable moulds mean the product can be made to accommodate a range of projects
- Instant stability
- Mammal ledges can be added to allow wildlife to safely pass through the culvert
- The ball and socket joint is typically located mid-height.
- Used for road infrastructure
- Bitumen coating can be factory applied if required
Portal Frames:
The portal frame system provides a faster and more cost effective alternative to cast in-situ abutments and bridge beams. Portal frames either consist of an n-shaped upper unit and 2nr L-shaped footings per ring, or simply just an n-section. Units can be designed to specified loadings and fulfil Eurocode requirements.
- Alternative to bridge beam construction
- Ball and socket joint between wall and roof
- Designed per project requirements
- Reduced insitu works
- Used for road infrastructure
- Bitumen coating can be factory applied if required
