Structural Strengthening
Sika® CarboDur® CFRP plates and SikaWrap® fabrics that add load capacity to beams, slabs and columns — without adding dead weight.
Overview
How we approach it
Structural strengthening increases the load capacity of existing beams, slabs and columns — most efficiently with bonded carbon fibre (CFRP) systems that add strength without weight. It's the answer whenever a structure must carry more than it was designed for.
Buildings outlive their original loading assumptions: floors change use, openings are cut in slabs, codes are updated, or construction defects reduce capacity. Traditional strengthening with steel sections and concrete jackets is heavy, slow and eats headroom. Carbon fibre changes that equation.
We design and install Sika® structural strengthening systems: Sika® CarboDur® pultruded CFRP plates bonded with Sikadur® structural epoxies for flexural strengthening of beams and slabs, and SikaWrap® carbon fabrics for shear strengthening and column confinement. The systems add millimetres, not centimetres, install in days, and are engineered case-by-case with calculations submitted for the consultant's approval.
Our crews are trained specifically on these systems — surface preparation, epoxy mixing and fibre orientation are exactly where CFRP jobs are won or lost.

Common questions
Frequently asked questions
What is CFRP strengthening and when is it needed?
CFRP (carbon fibre reinforced polymer) strengthening bonds carbon plates or fabrics to concrete with structural epoxy, increasing load capacity without significant added weight or size. It's used when floor loads increase, openings are cut in slabs, codes change, or construction defects reduce capacity — anywhere traditional steel jacketing is too heavy or slow.
How much load capacity can carbon fibre add to a beam?
Flexural capacity increases of 20–50% are routinely achievable, and shear or column confinement gains can be higher — but the real answer comes from calculation, not rules of thumb. Every Talhi CFRP project is engineered case-by-case with design calculations submitted to your consultant for approval before any fibre is bonded.
Does structural strengthening require evacuating the building?
Rarely. CFRP installation is quiet, fast and low-disruption — surface grinding, epoxy application and plate bonding typically proceed area by area while the building operates. Most projects complete in days. Compare that with concrete jacketing, which means formwork, casting, curing time and significant noise and dust.
