Over the past 10 years, the wet shotcrete method has become increasingly used in the repair of vertical and overhead concrete surfaces. The wet shotcrete admixture products, Spray-Con, are mixed on-site with locally supplied sand and Portland cement. Spray-Con's silica fume enhanced and fiber reinforced formulations make it easy to control air entertainment in shotcrete - an important requirement for freeze/thaw durability and salt-scaling resistance.
