Shotcrete is a construction method that involves spraying concrete onto surfaces at high velocity. This technique is often used for building structures like tunnels, swimming pools, and retaining walls. The application can be done using either dry or wet mixes, allowing for flexibility depending on the project requirements. The primary advantage of shotcrete is its ability to conform to complex shapes and provide a strong, durable finish. It is particularly effective in areas where traditional concrete pouring is challenging. Additionally, shotcrete can be reinforced with materials like steel fibers or mesh to enhance its structural integrity.
