Under-strength columns

Column wrapping is a technique perfected by Weber using a variety of specialist unidirectional or woven fibre sheets bonded with a strong epoxy glue. Many bridges and buildings have been repaired using this novel technique.


Reinforced concrete columns carry and transfer load from beams and slabs down to the foundations of the structure. Additional loads or deterioration of the column can result in overloading of the column, causing buckling and cracking of the columns. Shear cracks can develop when the column is severely overloaded.


Use near-surface mounted reinforcement and sheetwrap

Install manual lamination sheet wrap using either carbon, aramid or glass sheet depending upon the specific design and/or use near-surface mounted reinforcement, NSM, cut-in laminates.
