Prodemo overburden drilling systems offers three types of solutions for casing and drilling simultaneously,ODEX-P drilling, symmetric drilling and Concentric drilling , casing advancing in overburden has becomemore ingenious,Prodemo overburden tools enable simultaneous drilling-and-casing through overburden, passing easilythrough large boulders, soil, silt, clay, sand, and gravel not solid ground condition,Once the requireddepth is reached, the drill string is removed, leaving the casings in place to serve as channels for grout,cables or explosives.Prodemo overburden casings are always reused. Since the casings used with innovative systems can be light-weight and inexpensive.Prodemo three systems permit continued normaldrilling into the bedrock if required.
Today, drilled casings tools are used by more and more ground engineering contractors, which becomeone of the most popular methods for foundations, reinforcement work and well drilling. Which is designedfor urban work such as bridge,utility line, wharf and building construction.
