Performance and service life of repairs of concrete structures in The Netherlands
conference paper
In 2010, an inventory to the performance of repairs in the Netherlands has been executed, in response to reported low performances of repairs in Europe. Extensive records were collected concerning, among other, the age of the repairs and their current conditions in a similar way as in the European inventory conducted five years earlier. The results indicate that the failure rates of the Dutch repairs are similar to that of the European failure rates: ca. 20% failed within 5 years and 90% failed within 25 years. The failure of the repairs mostly was contributed to an insufficient execution (50%), in contrast to the European investigation. Here, more than 50% of the failure was contributed to incorrect diagnosis or incorrect design of the repair. The service life of most repairs was difficult to establish since either it had not yet ended or because the precise moment of failure (inside or outside the required service life) could not be established. © 2012 Taylor & Francis Group.
