The "structural" alternative involves constructing a seawall, revetment, groyne or breakwater. In shallow water, revetment breakwaters are usually relatively inexpensive. It was shown that the earthwork had a consistent design, with stone or timber revetment. There were two adjacent taxiways along both sides of the runway with revetment areas. These are placed as a revetment over gravel or rock. The building was originally decorated with a marble revetment and mosaics, which disappeared totally. The marble revetment also closely mimics the source work. The cracks in the revetment of Ballia Nullah have to be repaired urgently. These included fuel testing, a gun revetment, hydrostatic testing, static testing, and many others. The facility featured three revetment compounds. South of the revetment, development is limited to one row of single-family residences. Sergeant Troy McGill occupied a revetment with his squad of eight men.
