Hong Kong Airport completes third runway with advanced marine environmental protection

By PulseAugur Editorial · [1 sources] ·

Hong Kong International Airport has completed the construction of its third runway, employing innovative deep cement mixing techniques to manage contaminated sediment and avoid environmental damage. This method, unprecedented at this scale, involved injecting cement slurry into the seabed to solidify mud pits, thereby containing pollutants while anchoring the reclaimed land. The project also incorporated numerous other environmental protection and enhancement measures, including the installation of eco-enhanced sea wall blocks, artificial reefs, and the release of fish fry, contributing to the establishment of the North Lantau Marine Park.
