Structural Strengthening
When added load, a change of use or a construction error outruns what a frame was built to carry.
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.

A structural strengthening contractor
Delta is a structural strengthening contractor rather than a material supplier: the concrete strengthening described here is engineered, sealed and installed by one team. That matters most when composite turns out to be the wrong answer. A member short of stiffness rather than strength gets section enlargement, new distribution ribs or near surface mounted bars instead — specified by the same people, rather than a system recommended because it is the one being sold.
Systems we install
Carbon Fiber Strengthening
Carbon fiber strengthening is strengthening primarily for flexural applications due to it's high modulus for additional capacity with designed with the existing steel and concrete strength and can be coated to protect and also fire proofed.
Glass Fiber Strengthening
Glass fiber strengthening or e-glass is used primarily for shear applications and additional axial capacity on columns. It is also used in blast and flood protection because it can slightly flex and distribute the load.
