Geobear implemented a controlled geopolymer injection programme to improve ground stiffness and re‑establish uniform support beneath the carriageway.
Small‑diameter injection points were drilled through the pavement to introduce a two‑component geopolymer beneath the affected areas. Upon mixing, the material expanded to fill voids, bind loose materials and increase bearing capacity.
Injection was monitored in real time to ensure precise improvement and, where necessary, controlled re‑levelling of the pavement.
