Concrete Repair
GNWC crews have performed over 45,000 square feet of concrete repair on bridges, tunnels and other structures such as the underwater dome at the Seattle Aquarium.
We have been involved in multiple research projects to determine the best practices and products required to achieve a no- or low-shrink patch. We have achieved a 100% success rate on our concrete repairs given our commitment to quality and excellence. As an added level of protection, on many of our projects, we have installed embedded galvanic anodes in the concrete repair areas, to limit future corrosion of the rebar in the repair. Concrete by itself is extremely durable and very few natural compounds attack or degrade it. A testament to its strength and longevity can be found throughout Europe in still standing Roman era structures built from concrete. The steel used to reinforce and strength modern concrete is quite susceptible to corrosion though. The vast majority of concrete repairs we perform are caused by corrosion of the reinforcement steel within the concrete. To be able to properly repair the concrete and prevent future issues requires carefully analysis and consideration of the underlying issues in regard to protection of the steel reinforcement. GNWC brings a wealth of knowledge and expertise on how to tackle these issues. |
