A concise historical narrative of NAICS Code 238910-21 covering global milestones and recent developments within the United States.

  • Mud jacking, also known as slab jacking, is a technique that has been used for over a century to repair sunken or uneven concrete surfaces. The process involves drilling holes into the concrete and pumping a mixture of water, soil, and cement underneath to lift the slab back into place. The first recorded use of mud jacking dates back to the early 1900s in Germany, where it was used to repair the foundations of buildings damaged during World War I. In the United States, mud jacking gained popularity in the 1930s and 1940s as a cost-effective alternative to replacing concrete slabs. Since then, the industry has continued to grow and evolve, with advancements in equipment and materials making the process faster, more efficient, and more environmentally friendly. In recent years, the mud jacking industry in the United States has seen a surge in demand due to the increasing popularity of decorative concrete and the need to repair aging infrastructure. The use of mud jacking to repair concrete surfaces in public spaces such as sidewalks, parking lots, and bridges has become more common, as it is a cost-effective and non-invasive solution that minimizes disruption to traffic and pedestrians. Additionally, advancements in technology have made mud jacking more precise and efficient, with the use of computer-controlled equipment and high-pressure pumps. As the demand for mud jacking services continues to grow, the industry is expected to see further advancements in equipment and materials, as well as increased competition among contractors.
