Sample interview questions: Have you ever had to work on plumbing projects that required specialized trenchless techniques?
Sample answer:
Yes, I have experience working on plumbing projects that required specialized trenchless techniques. In these projects, I have demonstrated proficiency in utilizing various trenchless technologies, including:
Horizontal Directional Drilling (HDD): I have successfully employed HDD to install new underground pipelines with minimal disruption to the surrounding environment. This technique involves drilling a pilot hole along the desired path, followed by enlarging the hole to accommodate the pipeline.
Pipe Bursting: I have skillfully used pipe bursting to replace aging or damaged underground pipes without the need for extensive excavation. This technique involves inserting a bursting head into the existing pipe, which is then expanded to fracture and displace the old pipe while simultaneously pulling in the new pipe.
Cured-In-Place Pipe (CIPP): I have effectively applied CIPP to rehabilitate deteriorating underground pipes. This method involves inserting a flexible liner impregnated with resin into the existing pipe, which is then cured in place using heat or UV light to form a new, structurally sound pipe within the old one.
Slip Lining: I have expertly performed slip lining to renew damaged or leaking pipelines. This technique involves inserting a smaller-diameter pipe into the existing pipe, creating a new flow path while leaving the existing pipe in place.
Auger Boring: I have efficiently utilized auger boring to install new underground ut… Read full answer
