tunnels construction

Shotcrete is extensively used in tunnels and underground spaces for structural reinforcement. Its ability to bond well with rock surfaces makes it ideal for stabilizing walls and ceilings, particularly in mining tunnels and infrastructure projects. South African companies like Minecrete have employed this technology to line tunnels in complex mining operations, providing protection from weathering and structural weakening.

Thin Spray-On Liners (TSLs) are polymer-based coatings designed to adhere to rock surfaces, forming a thin, protective layer. These liners are used primarily in mining and tunneling to stabilize exposed rock faces immediately after excavation.

Tunnel linings refer to the permanent or temporary structural layers placed inside a tunnel to provide reinforcement and stability. These linings act as a barrier between the tunnel’s interior and the surrounding geology, minimizing risks like rockfalls, water ingress, and ground deformation.

When constructing tunnels, ensuring structural integrity and worker safety is paramount. Two critical elements in achieving this are shotcrete concrete and tunnel safety protocols. Let’s explore how these components work together to create safer, more durable underground environments.
