Structural Strengthening

The ability to obtain the solution not obtainable through traditional methods

Structural strengthening is the process of upgrading the structural system of an existing building to improve performance under existing loads or to increase the strength of the structural components to carry heavier loads. The effects of strengthening or removing part of a structural component must be analyzed carefully to determine their influence on the global behavior of the structure. Failure to do so may over-stress the structural elements surrounding the affected area, which can lead to a bigger issue and localized failure.

Design, Expertise, Experience

Delta’s approach to structural strengthening is innovative, structurally efficient and cost effective by using externally bonded FRP sheets. FRP provides high strength, light weight, non corrosive, cost effective solutions for new and existing structures. Composites in the form of paper thin fabric sheets and epoxy adhesives create strength up to 10 times that of steel.  In today’s world,  a steel alternative is cost-effective because the cost of steel is at an all time high.  At Delta, we have the key to success in FRP engineering. Delta analyzes, designs, engineers and applies FRP along with other strengthening methods to achieve optimal results.
