Shotcrete is often the most cost-effective solution for construction of structural walls that are placed against existing concrete/masonry walls, shoring systems or any other single sided forming situation. Examples of structural walls where shotcrete construction offers the greatest benefits are seismic shear wall upgrades, strengthening of existing walls with installation of sister walls, single sided forming concrete situations and foundation walls placed directly against shoring systems. As a result of the high cement content and density, pneumatically placed shotcrete can easily be designed to meet any standard concrete specification. Shotcrete installation of structural walls often can be completed at a reduced cost compared to concrete depending on the wall heights. As wall heights increase the cost savings shotcrete construction offers increases along with it. Substantial time saving can also be offered by shotcrete installation techniques.
