Concrete is a strong and durable material, but that doesn’t mean additional structural strengthening won’t be needed. Over time excessive use and wear can cause a structure to become unstable. To retain it and maximise safety extra strength is essential. Having worked with many different concrete structures, our team have an unsurpassed knowledge when it comes to implementing safety measures such as these.
Fibre-reinforced polymer (FRP) composites have seen use in structural strengthening efforts across the world for many years. During this time, acceptance of these materials within the mainstream construction industry has increased dramatically. As a result, the number of projects that use FRP to add strength has risen as well.
This type of material is made up of top-level continuous fibres, including steel wires, glass and carbons, which are embedded within a polymer matrix. The fibres make up the prime reinforcement components while the matrix protects the fibres and transfers loads between and to them.
The composites can be created on site through the use of the wet lay-up process. During this operation, a dry fabric made of glass or carbon is mixed with epoxy and merged to concrete substrates. After they’ve been cured, FRP’s become a vital aspect of the structural element and act as an externally bonded reinforcement network.
FRP composites can also be fabricated beforehand at manufacturing facilities, where the materials are pultruded to develop unique shapes. These can be used for many structural strengthening purposes, such as on plates, rods and bars.
At Churchill Concrete Technology we have worked to strengthen numerous structures, including the likes of buildings, bridges and roads. In terms of both cost effectiveness and being undisruptive, we always work hard to provide the best solutions for our clients. This has helped us to become a leader in our field.
