Our company specializes in the "Pneumatic Caisson" method. The "Pneumatic Caisson" is a construction method that applies the principle of preventing water ingress by using air pressure, similar to the state of pushing a cup upside down underwater while ensuring that the air inside does not escape. This cup is a large structure made of concrete (or steel in some cases), and high-pressure air generated by a compressor is sent inside while the structure is being sunk into the ground. *For more details, please download the PDF or contact us.*
