Concrete is a strong, durable material that can last a lifetime if properly cared for and protected from harsh environmental conditions. However, over time, like our skin and hair, it shows its age with cracks, discoloration and spalling. In many instances, these issues are merely cosmetic and do not affect the integrity of the concrete structure. However, it is important to recognize when cracks and spalling become a structural concern.Resource :

In these situations, Concrete Repair is needed to prevent further deterioration and prolong the life of the structure. A thorough inspection is recommended to determine the underlying cause of deterioration or damage and to select appropriate repair methods. The evaluation should include a review of design and construction documents, a visual inspection, destructive and non-destructive testing, laboratory results of chemical and petrographic analysis of concrete samples, and any maintenance records that are available.

Routing and sealing is a relatively simple concrete repair method that consists of widening the crack with a router then filling it with an appropriate sealant. This method is generally used for dormant cracks but can be used on active cracks as well if a suitable filler is selected. The V-shaped cut created by routing allows the sealant to better expand and contract with the movement of the crack thereby prolonging its lifespan.
