The use of reinforced concrete elements within a structure remains one of the most economically viable methods of construction within Australia . Like everything else in life however it requires maintenance to prolong its working life. When reinforced concrete elements are subjected to aggressive elements such as chlorides (from sea spray or chemicals) or carbon dioxide from the atmosphere it can lead to catastrophic results. The reinforcing steel expands as it rusts deep inside the concrete resulting in cracks and spalling that decrease the strength of the structural elements. When this happens the damaged concrete needs to be repaired by specialists who understand the work methods and propriety materials that assist in redevelopment of strength and durability of the structure. Crest Restorations specialize in traditional hand applied concrete repair techniques as well as state-of-the-art repair procedures such as hydro-demoltion and gunite repair. Our expertise includes the use of electrochemical techniques such as cathodic protection and cathodic prevention. By using specialized titanium and zinc anodes a full design and installation service can be provided to ensure that corrosion is totally stopped in your structure or building.
