Industry Innovations for NAICS Code 237990-19

Recent groundbreaking advancements and milestones in the Caissons-Structural industry, reflecting notable innovations that have reshaped its landscape.

  • Use Of Micropiles: Micropiles are small-diameter piles that are used to support structures in areas with limited access or space. They are often used in urban areas where traditional foundation methods are not feasible. Micropiles are made of high-strength steel or concrete and can be installed quickly and efficiently.
  • Use Of Helical Piles: Helical piles are a type of deep foundation system that is used to support structures in areas with poor soil conditions. They are made of steel and have helical plates that are screwed into the ground. Helical piles are easy to install and can be used in a variety of soil conditions.
  • Use Of Precast Concrete Piles: Precast concrete piles are precast in a factory and then transported to the construction site. They are used to support structures in areas with poor soil conditions or where deep foundations are required. Precast concrete piles are strong, durable, and can be installed quickly and efficiently.
  • Use Of Composite Piles: Composite piles are made of a combination of materials such as steel, concrete, and fiberglass. They are used to support structures in areas with poor soil conditions or where deep foundations are required. Composite piles are lightweight, strong, and corrosion-resistant.
  • Use Of Jet Grouting: Jet grouting is a soil stabilization technique that involves injecting a high-pressure stream of grout into the soil. It is used to improve the strength and stability of soil in areas where traditional foundation methods are not feasible. Jet grouting is fast, efficient, and can be used in a variety of soil conditions.
