FRP Concrete Strengthening Applications
Fiber reinforced polymer (FRP) has a wide range of consumer, commercial and public sector applications.
In the commercial and public sectors, the most common FRP application is concrete strengthening.
There are three common scenarios where FRP has proven to be more economical than traditional strengthening methods:
- Increases to a structure’s load capacity beyond the original specification or expectation
- Seismic strengthening
- Repairs to concrete structures that become damaged over time
In all cases, FRP has less spatial impact on the structure than traditional methods. It is a thin, yet high strength material. This translates into benefits such as not reducing a bridge’s clearance by more than the width of the material (less than 3 millimeters) plus the thin bonding and protective layers.
Low spatial impact can also mean not sacrificing any rentable space in a commercial structure such as a parking garage or a warehouse.
It can mean not decreasing the flow rate through a pipeline by a consequential amount.
Another benefit to FRP is that it can be used in tight work spaces that may be inaccessible with traditional methods and materials.

Concrete is just one of three substrates where FRP is commonly applied. Other common strengthening applications include masonry and timber.
