Sika CarboShear CFRP Strengthening
Slabtec recently completed a structural strengthening project at a School in regional Western Australia, utilising the Sika CarboShear CFRP shear reinforcement system to increase the shear capacity of existing reinforced concrete elements.
The externally bonded carbon fibre solution provided a high‑strength, low‑impact method of upgrading structural performance while minimising disruption to the operational school environment.
Adaptive Reuse – structural strengthening
As buildings evolve over time, structural elements may require strengthening to accommodate increased loads, updated design standards, or deterioration of original construction materials. Slabtec was engaged to provide a targeted strengthening solution for the School to existing reinforced concrete members that required additional shear capacity.
The project utilised a bespoke strengthening solution called Sika CarboShear, which is a preformed carbon fibre shear plate. The L‑shaped CFRP profiles are externally bonded to reinforced concrete beams using high‑performance epoxy adhesives, enabling engineers to increase shear capacity without extensive structural alteration or demolition.
Why CarboShear?
This was a unique solution to the structural strengthening issues at the school and has been deployed in Australia only a few times.
Sika CarboShear links offer several advantages for strengthening existing structures:
- High strength‑to‑weight ratio
- Small profile allows strengthening around existing fixtures and fittings
- Minimal additional structural weight
- Rapid installation with minimal disruption
These characteristics make CFRP strengthening particularly well-suited to operational environments such as schools, where maintaining safe access and minimising disruption are critical considerations.
Slabtec Specialist Installation
Slabtec has developed a unique capability for installing the Carbon-Shear system in Australia. Using our specialist knowledge of CFRP, structural elements, and technical design, Slabtec’s team delivered the installation on time and on budget.
These projects highlight how advanced strengthening technologies can extend the life of existing structures while avoiding the environmental and financial costs associated with demolition and reconstruction.
