A seawall, made of rocks in Paravur near Kollam city in India. Seawall construction has existed since ancient times. In the first century BCE, Romans built a seawall or breakwater at Caesarea Maritima creating an artificial harbor (Sebastos Harbor). The construction used Pozzolana concrete which hardens in contact with seawater. Barges were ...
The Galveston Seawall is a seawall in Galveston, Texas, that was built after the Galveston hurricane of 1900 for protection from future hurricanes. Construction began in September 1902, and the initial segment was completed on July 29, 1904. From 1904 to 1963, the seawall was extended from 3.3 miles (5.3 km) to over 10 miles (16 km). [2]
Construction materials commonly used include wood pilings, commercially developed vinyl products, large boulders stacked to form a wall, or a seawall built of concrete or another hard substance. Coastal property owners typically seek to develop bulkheads in an attempt to slow large landslide erosion caused by wave action.

Cunningham continued supervising construction into his last days despite being ill and, on at least one occasion, went to check the seawall's progress still wearing pajamas. He died on 29 September 1963, long before the wall was finished, but remains the one most associated with the project, and a commemorative plaque can be found near Siwash ...
Cost comparisons between various seawalls are always site specific, but Seabees use approximately 22% the mass of rock for the same exposure. As the area of the unit is sensibly independent of height [aspect ratios in use vary from 0.4 to 2.5] the mass of the unit can be optimised for all stages of the production and construction process.
