Sample interview questions: Can you explain your experience with using pipe bursting or pipe lining techniques for drain repairs in environmentally sensitive areas?
Sample answer:
- Pipe Bursting:
In environmentally sensitive areas, pipe bursting is a trenchless drain repair technique that effectively replaces old, damaged pipes with new ones. The process involves inserting a bursting head into the existing pipe, expanding it radially, and simultaneously pulling a new pipe behind it.
- Pipe Lining:
Pipe lining, also known as cured-in-place piping (CIPP), is a trenchless drain repair technique that involves inserting a flexible liner into the existing pipe. The liner is then inflated, cured, and hardened, creating a new, seamless pipe within the old one.

Experience in Environmentally Sensitive Areas:
-
Careful Assessment: Before undertaking any drain repair in environmentally sensitive areas, a thorough assessment of the site is crucial. This includes identifying any potential risks to the surrounding environment, such as sensitive plant species, water sources, or protected habitats.
-
Minimizing Environmental Impact: To minimize the environmental impact, pipe bursting and lining techniques are preferred as they require minimal excavation and disruption to the surrounding area. Proper planning and careful execution are essential to prevent any harm to the environment.
-
Proper Equipment and Materials: Selecting the right equipment and materials is crucial in environmentally sensitive areas. This may include using specialized bursting heads, liners, and resins that are designed to … Read full answer
