What You Need to Know when considering a Micropile Deep Foundation System

Magnacore Micropiles are the perfect solution for a wide variety of deep foundation projects. Magnacore hollow bars are an excellent consideration when deep foundations are needed for projects such as micropiles for new building construction, foundations for bridges and towers to the repair or fortification of existing structures. They have become a popular choice thanks to their versatility and functionality in challenging soil conditions.

Micropiles Specifications for Deep Foundation Systems

Intech Anchoring recognizes there is no single deep foundation system that is the best fit for every situation. Soil conditions, obstructions, and access limitations can alter the needs of any project, and finding the right product requires recommendations from professional experts like the engineering team at Intech Anchoring. Some of the most challenging subgrade conditions consist of elements like buried construction debris, boulders, large areas of void or collapsing soil. When you encounter these conditions, micropiles are often the best option.

Micropiles themselves are small diameter (typically under 10” in diameter) grouted piles that have a central steel element for reinforcement. Load capacity of the micropile is accomplished through the skin friction between the grout and the surrounding soil as well as the bearing surface at the end of the element. Micropiles can be designed to handle high-capacity loads (in excess of 500 Kips). Magnacore hollow bar micropiles install quickly, even in the most challenging soil and site conditions.

Micropiles Offer Rapid Installation in Areas of Limited Access

The most significant reason that Magnacore Micropiles have risen to such prominence is their ease of installation. Thanks to their functional design, with segmented sections, they can be installed in situations with low overhead clearance. Where other foundation systems might require large, heavy machinery, micropiles are installed with smaller equipment such as a skid steer or excavator. Specialty Contractors turn to the cost-effective and high-quality materials of Magnacore micropiles as their first choice when you are faced with challenging soil conditions and on a tight timeline.

Another advantage of our Magnacore Micropiles is the efficient installation process. Featuring single, top-down operation with the grout being installed simultaneously with the drilling of the hollow bar micropiles, there is no faster installation process. This process allows the micropile to be drilled and grouted at the same time. The grout flows out of the ports in the sacrificial bit that is used to advance the hollow bars to depth.  This neat grout mixture actually permeates into the surrounding soil to create a dependable, reinforced grout column. Other deep foundation systems require the grout injection to occur separately after the hole has been completely drilled. With Magnacore, the single pass installation of both the hollow bar and the grout together saves significant cost on labor hours.

Micropile Applications and Projects

The competitive cost of hollow bar micropiles and their versatile applications make them a popular choice for a wide variety of projects. By eliminating the need for extra steps in the installation process, they make your entire project more cost effective. The advantage of micropiles includes:

  • Rapid, One-Step Installation
  • Simultaneous Drilling and Grouting
  • Utilzation of Smaller Equipment for limited access projects
  • Works in Low Overhead Conditions
  • Works within collapsible soil profiles
  • Extremely High Loads can be achieved
  • Provides a High Skin Friction
  • Grout encasing the steel hollow bar increases the Corrosion Protection

Magnacore Micropiles are the optimal choice for a variety of situations, including:

  • Limited Access Areas / Low Overhead
  • New Construction and Retrofit
  • Design/Build
  • Cased and Uncased Applications
  • Challenging Site Conditions
  • Rock and Obstructions below grade
  • Tower and Bridge Foundations
  • Tiebacks and soil nails
