Concrete Canvas® GCCM* in Action: Renewing Concrete Water Canals Across Hungary
In November 2018, Concrete Canvas® (CC) GCCM* was used to remediate a 200m long section of an existing concrete irrigation channel connected to the river Tisza in Tiszafüred, eastern Hungary. The section in question is part of a large 36km long canal constructed around 80 years ago, which feeds off onto several smaller canals. The total length of this canal network is more than 80km. The canal is operated by Middle Tisza District Water Directorate, who manage more than 4300km of canals, rivers and waterways across the area, which are mainly used for irrigation, supplying water to farms, fisheries and so on.
Several stretches of the canal showed severe damage to the concrete in places, which were drastically impacting the hydraulic performance of the canal and causing fairly severe leaks. This project was carried out on a trial basis to establish how well CC would perform in this application. This particular 200m stretch was chosen as it was closest to urban land facilitating transportation issues. This section of canal is also situated on an embankment, so monitoring the result of the repair would be easy to carry out. Should the trial prove a success, the client will look into using CC for remediation of other damaged sections of the canal network.
