In addition to building homes, shotcrete can also be used to build pools. Methods of Application Wet Mix All ingredients, including water, are thoroughly mixed and introduced into the delivery equipment. Wet material is pumped to the nozzle where compressed air is added to provide high velocity for placement and consolidation of the material onto the receiving surface. Dry Mix Pre-blended dry or damp materials are placed into the delivery equipment. Compressed air conveys material through a hose at high velocity to the nozzle, where water is added.
Material is consolidated on the receiving surface by the high-impact velocity.
Fibers - Control cracking, increase toughness values and improve impact resistance and energy absorption. Accelerators - Improve placement characteristics in adverse conditions, allow for thicker single pass applications, increase production capabilities and reduce the occurrence of fallouts on structures subjected to vibration. This system consists of prefabricated panels of polystyrene insulation sandwiched between two parallel sheets of wire mesh, and sprayed with concrete on-site. Incredible strength comes from the galvanized wire that pierces the insulation at acute angles. It is welded to both sheets of wire mesh to create a truss-like support system of incredible strength.
