Case Study 

Impact protection of columns with S&P A-Sheet 120 (FRP 2013_04)

Solution 

The concrete columns in the warehouse storey need to be protected against impact damage. This must cover load combinations that include vehicles of up to 3.5 tons and forklift trucks. The static calculations show that the bottom 1.5 metres of the columns must be wrapped in a layer of S&P A-Sheet 120. The reinforcement mesh, made from aramid fibres (E-modulus 120 kN/mm2), is stuck onto the prepared substrate with the vapour-permeable epoxy resin S&P Resicem, forming a load-transferring adhesive bond.

Material 

per column, 8 m2 S&P A-Sheet 120, width of roll 300 mm
