Rope Access is 50-80% less expensive than scaffolding, cranes and other forms of at-height access. Fewer people are required to accomplish the same work, and the project is completed sooner because of the increased mobility and efficiency of rope access work. These factors work to minimize downtime, which in turn lowers costs.
Concrete structures are exposed to severe environmental influences over extended lifetimes. Corrosion is a major factor in concrete degradation. The reinforced steel or ‘rebar’ corrodes and causes the concrete to crack and come away from the facade. Untreated, this can become a major problem that can affect the integrity of the structure or can leak.
The Repair Process:
We begin the process by carrying out an inspection the effected area, removing all the delaminated (drummy) concrete and render, profiling the reinforcing steel to remove all traces of corrosion. The reinforcement is then treated with zinc-rich anti-corrosives. A fibre cement based system is then used to repair the patch and a render is applied to match the original facade. A paint coat may then be applied.
Complex rigging, lifting and fitting operations can be performed safely and quickly in otherwise impossible locations, or where scaffolding would usually be required. Setting up and de-rigging of rope access equipment takes only minutes in most cases allowing the work to start quickly, and also allowing work to cease temporarily if necessary, without any disruption to other work parties, processes, plant or equipment.
Potential applications for rope access continue to grow thanks to wireless technology and tools that allow technicians to complete old jobs in new ways.
