History

A concise historical narrative of NAICS Code 237990-11 covering global milestones and recent developments within the United States.

  • The use of retaining walls dates back to ancient civilizations such as the Greeks and Romans, who used them to hold back soil and create terraced landscapes. In the 18th and 19th centuries, retaining walls were used extensively in the construction of canals and railroads. The development of reinforced concrete in the late 19th century allowed for the construction of taller and stronger retaining walls. In recent history, the use of retaining walls has expanded to include landscaping and residential applications, with the introduction of new materials such as interlocking concrete blocks and natural stone. In the United States, the use of retaining walls became more widespread in the mid-20th century with the growth of suburban development. The development of new materials and construction techniques has allowed for the construction of taller and more complex retaining walls. In recent years, there has been a growing trend towards the use of environmentally friendly materials and techniques in retaining wall construction, such as the use of recycled materials and the incorporation of greenery into the design.
