ROMTECH® Lattice Girders in conjunction with shotcrete provide strata control for infrastructure tunnelling applications. Suitable for use in hard rock or soft ground conditions. ROMTECH® complies with all relevant Australian standards.
ROMTECH® Lattice Girders provide structural arch support in tunnelling applications. Suitable for hard rock and soft ground conditions, ROMTECH provides high strength-to-weight ratios and is available in a wide range of sizes that can accommodate complex radial geometries. When used with mesh or fibre reinforced concrete, they form a continuous reinforced concrete shell, which can support both temporary and permanent loadings. Lightweight and easy to handle on-site, ROMTECH® reduces shotcrete cycle times and shadowing. ROMTECH® Lattice Girders are available in a wide range of cross sectional sizes and designs.
