Today i decided to further my knowledge about the pipes that used at Putra Jaya. I learned about the specification of the design, construction and tests requirement for single & double wall HDPE corrugated pipe which is used primarily for underground cable installation in Putra Jaya.

In general, concrete of grade 15 is commonly used for underground cable installation in Putra Jaya.
Different classes are also used as the specified design and requirements.
