Unusual Rigging, a supplier of rigging and technical solutions for the entertainment and events industries, needed an efficient and high performance concrete solution for the construction of a storage shed used to house components for the manufacture of rigging assemblies.
Sika and Hanson recommended the use of the Sika VisoCrete admixture to provide good workability, along with Sika Durus Macro Fibres, as an alternative to steel mesh, because the space on site was limited and the timeframe was crucial.
Steve Armfield, Product Development Manager at Sika, commented: “One of the main challenges on the project was speed of construction, with our recommendation to use macro fibres to replace the steel mesh. This made it easier to place the concrete without the hassle of setting up the mesh prior to pouring concrete.”
Used to enhance the toughness of the concrete, the Durus Macro Fibre S300 gave the contractor the benefit of placing the 250m3 of VisoCrete concrete into the restricted areas through a pump.
“Steel mesh is very labour intensive and can lead to an increased risk of health and safety issues during installation. Another drawback is that the steel can also corrode and rust, causing unsightly staining on the surface of concrete,” added Steve.
