Mainmark used a bespoke engineered solution, including their proprietary Terefil to reline, repair and future-proof the $1.6 billion Toowoomba Bypass development’s key drainage. Terefil’s lightweight, cementitious fill material, consisting of cement slurry and pre-formed hydrocarbon foam, provided stability and longevity to one of the largest infrastructure investments in Queensland history.
