Near-surface mounted reinforcement

Strips are applied directly on the surface of a structure that is pretreated, e.g. by grinding or sand-blasting, using a two-component epoxy adhesive. Another technique is the so-called near surface mounted reinforcement (NSMR), which means that the strips are embedded into slits in the... 

An alternative or complementary technique based on near surface mounted reinforcements and called NSM consists in inserting FRP rods with an epoxy adhesive or cement grout into grooves cut in the concrete member (De Lorenzis and Teng, 2007).
