For engineers and owners, deteriorating bridges and concrete structures represent a major safety issue as well as imposing a growing financial burden. It is therefore imperative to find cost-effective solutions to investigate and optimize the maintenance of existing structures.

Our team of engineering specialists and experts can travel anywhere in Ontario to perform on-site inspections and offer in-depth insight into the often-complex problems of deteriorating concrete structures. HAL’s investigation techniques and methodologies used are always adapted in scope according to the complexity, type, and size of the structure being investigated.

Based on the review of available documentation, HAL classifies the type of damage observed and the level of severity and evaluate the source and mechanism of deterioration. For each element and associated damage classification, an in-situ activity (i.e., coring, inspection and/or NDT) and testing plan are developed.
