Construction processes require very specific approaches and techniques, especially wherever repurposing old materials are concerned. When it comes to working with concrete, and more specifically, the re-bar beneath it, repurposing can be tricky since the materials need to be painstakingly prepared for use. This means that all old and unused materials need to be stripped from the bar, and it needs to be done in such a way as to not damage it. There are a number of approaches to doing this, and most of them pose a significant risk of causing damage to the materials they are preparing, hydrodemolition on the other hand, provides one of the safest and effective ways of doing so. But what is it? How does it work, and which industries stand to gain the most out of using this technique?
What Exactly is Hydrodemolition, and How does it Work?
Hydrodemolition is a process by which excess or old materials are cleared from a surface by means of high pressure water spraying. The process is far safer than other more traditional means of surface preparation, and is also more efficient and effective. It is best used for the removal of concrete, asphalt and grout, and is therefore a great approach to a necessary step when repairing roads, concrete structures and many other surfaces that are otherwise too durable to be removed with ease.
Through the process, top layers of surfaces are removed so that repairs can be made on them. Typically, only around a quarter of an inch of the top-layer is removed, though depth will depend on the task at hand.
Maintenance and repairs on bridges often require the top-layer of concrete to be removed, and when doing this, all efforts should be taken not to damage the layer of rebar below it. For this application, hydro blasting provides one of the safest and more effective means of doing this, while also ensuring that the bridge can be made usable in the shortest amount of time.
Harbour Repairs and Maintenance
Maintenance and repairs around harbours requires the removal of grout from boats and surfaces that may be easily damaged if done with the wrong approach. It is because of this
Water blasting can also be used to good effect when conducting road repairs. They can significantly extend the amount of time it takes before complete repairs need to be made by continually refreshing the layer of rebar beneath the road’s surface. The process can also be used on runways to remove rubber from the strip without damaging the tarmac or making it uneven.
Buildings and Construction Repairs
Where construction is concerned, water jetting is an excellent means of repairing damaged structures since it has a more versatile reach and has the ability to remove micro-fractures from a rebar’s surfaces, so that a fresh layer of concrete can be applied to it in a structurally sound manner.
