Tsala-RMS uses the world renowned VSL systems and components for all it's post-tensioning, retained earth and heavy lifting works. With a local team of specialised engineers and experts, combined with readily available international expertise, Tsala-RMS carry out complex and innovative engineering projects throughout Africa and the Indian Ocean islands.
Post-Tensioning
The bonded Post-tensioning system is used in heavy civil works, such as bridges, reservoirs, silos etc and allows a number of strands to be used in one duct or sleeve. The sleeve is then later filled with cementatious grout for bonding purposes and corrosion protection.
The unbonded Post-tensioning 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 sufficient strength.
Both systems allow structures to have greater spans as well as reduce propping time whilst the concrete is attaining it's 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.
Tsala-RMS Construction Solutions can be contracted to carry out one or a combination of the following:
- supply of materials only
- supply of materials, equipment and training
- full supply and installation
Design can either be done in-house or in conjunction with the professional engineer of record.
Heavy Lifting
The VSL Heavy Lifting System has been developed so as to provide safe and cost effective solutions for the lifting, lowering and horizontal movement of large and heavy loads. The flexibility of the system allows it to be applied to all types of structures such as bridge decks, silo roofs, mine headgears, power station turbines, etc.
Retained Earth
VSL Retained Earth is an advanced and economical soil stabilisation system. The system utilises three components - reinforcing mesh, precast facing panels and backfill material to create a composite soil reinforcing system. Project cost savings of up to 50% are regularly realized as well as producing an aesthetically and enviromentally pleasing structure.
VSL Bars
High strength fully threaded bars and components are available in the following diameters:
18; 26.5; 32; 36; 40 and 47mm.
