Averda is a multifaceted global company that operates in South Africa. The business specialises in waste management services, including recycling and landfill management. However, Averda offers other services too, such as cold cutting and hydro demolition. These processes involve using water to cut and demolish structures.
Both steel and concrete can be cut using highly pressurised water mixed with abrasive particles that jet out of a nozzle. Cold cutting and hydro demolition are methods that are safe for the environment.
They are most commonly used in sensitive or explosive environments where buildings and substructures, such as pipes, need careful deconstruction. Averda’s cold cutting and hydro demolition services use the latest machinery and technology. Our systems are fully-automated with a high production rate.
Advantages of cold cutting
Cold cutting is the best method for maintaining, modifying and deconstructing pipes that carry hazardous substances, such as hydrocarbons. Cold cutting technology has been developed to eliminate the hazards associated with thermal cutting methods – using a source of heat to cut pipes that contain flammable gases and liquids could result in an explosion.
Cold cutting ensures the safety of contractors, employees and bystanders. It also saves time as the cuts are much cleaner than thermal methods, which means that no additional weld preparation needs to be done on pipes. Using cold water jets to cut pipes also offers a good return on investment as the process is not as costly as thermal cutting.
Advantages of hydro demolition
Hydro demolition is a sustainable method for removing concrete and steel structures. It uses pressurised water to cut and blast concrete buildings, tar roads and steel rebar. Hydro demolition also provides a clean and smooth bonding surface that enables quick repairs to be completed if necessary.
Hydro demolition is an excellent method for exposing steel rebar within concrete structures, without having to remove all of the concrete. It allows contractors to repair and replace damaged or corroded rebar, then pour new concrete over the exposed steel. Unlike jackhammers and conventional concrete demolition equipment, hydro demolition does not produce vibrations throughout the concrete structure, which does not create microfractures and cracks.
Cold cutting and hydro demolition are safe for the environment
Both cold cutting and hydro demolition are safe for the environment because water is the primary cutting source. Both of these methods of deconstruction produce no dust pollution and they are quieter than conventional demolition equipment and tools. There are no harmful byproducts created by either of these methods.
The water used in the process of cold cutting and hydro demolition ban be collected and recycled. This expended water can be stored, cleaned and reused once again for demolition purposes.
