How are micropiles structured?
Micropiles are small-diameter grouted piles with steel reinforcements. They have two main sections in their structures:
- Standard Lead Section: This section contains various drill bit types, and it enters the ground first.
- Steel Reinforcement/Casing: This section strengthens the pile so it can withstand high-capacity loads.
How do micropiles work for foundation repairs and rehabilitations?
When you install micropiles in a compromised foundation, the installation transfers the load to the micropiles. Then the micropiles transfer their load to more competent soil or rock surrounding the foundation’s compromised parts.
What other applications do micropiles have?
Along with foundation repairs, micropiles work well for deep foundation construction. They also stabilize adjacent structures around deep foundations. Micropiles work well for these applications because they stabilize difficult terrain, such as sloping rock and Karst formations.
Do micropile projects require large budgets?
No, they do not. Drilled pier foundations often overrun their budgets because they require extra rock coring to complete the foundation. Micropiles avoid this problem by extending down into the rock formation and transferring the loads away from the drilled piers using skin friction. Once you apply micropiles to your foundation project, you have mitigated the risk of running over budget.
What types of construction projects benefit from the use of micropiles?
Micropiles work well in a variety of construction projects. They help bridges, towers, and new buildings maintain solid foundations. However, micropiles’ popularity has grown in recent years because they work well in difficult construction projects. These projects include ones with restricted access, weak soil, and low clearance. Micropiles are also customizable and cost effective, and these factors also contribute to their popularity. Overall, micropiles benefit construction projects that need to strengthen their foundations and that have restricted budgets.
What benefits do micropiles offer?
Micropiles offer the following benefits to construction projects:
- Quick installation process
- Consistent, reliable results across different project types
- Control of wear and tear and corrosion caused by soil
These benefits create a stronger foundation and overall structure in the long run.
