Guniting is an effective technique, which is extensively used in the rehabilitation of structurally distressed concrete work. There has been case of heavy rusting of the mesh in the form of powder or in the form of a sheet coming out. Distressing before restoration is possible only in case of overheads tanks which can be restored when the tanks are empty. Guniting is also known as Shotcrete or Pneumatically applied mortar. It can be used on vertical and overhead, as well as on horizontal surfaces and is particularly useful for restoring surfaces spalled due to corrosion of reinforcement. Gunite is a mixture of Portland cement, sand and water, shot into the place by compressed air. Sand and cement are mixed dry in a mixing chamber, and the dry mixture is then transferred by air pressure along a pipe or hose to a nozzle, where It is forcibly projected on to the surface to be coated. Water is added to the mixture by passing it through a spray injected at the nozzle. The flow of water at the nozzle can be controlled to give a mix of desired stiffness, which will adhere to the surface against which it is projected. A cement- sand mix, in the ratio 1:2 or 1:3 depending upon the requirement, is applied at high pressure over the surface with the help of specialized equipment. Guniting treatment gives results in few days and make concrete strong to resist water or moisture. We assure to provide the quality work of Guniting to our customers at very reasonable charges.
