Construction Solutions
VSL offers construction solutions relating to post-tensioning, retained earth, bridge bearings and heavy lifting using the internationally recognised VSL system.
For more details, you can visit the VLS Construction Website.
The parent entity is a Swiss specialist construction company that has developed proprietary post-tensioning and stay-cable systems.
Bonded post-tensioning systems
- Used in heavy civil works, such as bridges, reservoirs, silos etc.
- Allows multiple strands to be used in one duct or sleeve
- Cementitious grout is employed for bonding and protection against corrosion
Unbonded post-tensioning systems
- Slab and beam applications in reinforced concrete building structures
- Uses single strands contained in plastic sheaths
- Sheaths are cast into concrete and subsequently tensioned
Advantages of post-tensioning
- Enables greater spans
- Reduces propping time
- Significant cost and time savings
- Applicable to stay cables, external cables and ground anchors using strand or bar systems
The VSL Construction Solutions offering
- Supply of materials only
- Materials, equipment and training
- Comprehensive supply and installation
- Inhouse design or collaboration with the professional engineer of record
The unbonded system is generally used in the slab and beam elements of reinforced concrete building structures. This system makes use of single strands contained in plastic sheaths, which are cast into the concrete and then tensioned once the concrete has reached succinct strength.
Both systems allow structures to have greater spans as well as reduce propping time whilst the concrete is attaining its full strength. These advantages result in significant cost and time savings. The post-tensioning principle is also applicable to stay cables, external cables and ground anchors using strand or bar systems.
