| 41. | During the construction phase of the dam, river diversion was effected through two concrete lined diversion tunnels constructed on the left bank.
|
| 42. | Ponsolle said that repairing the 280-meter ( yard )-long damaged section will require restoring some of the concrete lining that chipped away.
|
| 43. | The tunnel at the headwater of the Zanja Madre was reconstructed and much of the conduit was either brick or concrete lined.
|
| 44. | Officials said that under intense heat in the tunnel, large chunks of concrete lining fell from the ceiling, further complicating rescue efforts.
|
| 45. | If a spillway had been built in the weathered sedimentary rocks at the dam site full concrete lining would have been required.

| 47. | At the site of the fire, the concrete lining of the walls spalled down to the ribs of the cast-iron primary lining.
|
| 48. | DID district engineer Mohamad Deris said the river reserve had 70 squatter houses which were holding up concrete lining work along Sungai Ampang.
|
| 49. | It is called engineering marvel because canal water reaches on elevated areas and canal has many pumping stations and NMC is concrete lined
|
| 50. | Malfunctions then forced the train to stop, and the tremendous heat damaged 1, 500 feet of track and 150 feet of concrete lining.
