China Communication Construction Company engaged us for a critical infrastructure project on reclaimed land, which presented unique challenges due to its high water table. The project required the excavation and installation of an underground pipe network, necessitating innovative solutions to prevent water ingress and soil collapse. To address these challenges, we implemented a well point dewatering system to manage the sea water effectively, allowing safe and stable excavation. Additionally, the project called for the construction of manholes with strict waterproofing requirements to ensure long-term durability and performance.
