The micropile is formed in a single, top-down operation by the injection of a high-pressure, neat cement grout mixture, which is pumped through the bar and serves as the drill string. The neat grout mix exits through grout ports at the end of the sacrificial bit and permeates into the looser adjacent soils. This mix and permeation are what forms the competent reinforced grout column.
Magnacore anchors are self-drilling, meaning that there is no pre-drilling required and grouting is part of the installation process.
Magnacore micropiles are suitable for a variety of applications and are particularly useful with projects launched in areas with limited access or weak soil. Micropiles have become a preferred method of deep foundation stabilization for their reliability, versatility, and efficiency.
A tieback is a horizontal rod used to reinforce retaining walls for stability. With one end of the tieback secured to the wall, the other end is anchored into the earth with sufficient resistance. By utilizing Magnacore SDAs for tiebacks, you can save time and is more cost effective with the quick, efficient, all-in-one installation.
Earth retention systems are constructed to provide support where deep excavations are required or slope stability is a concern. The design of these systems must consider movement control, stability during construction, and wall drainage. Magnacore can be used for jobs specified to stabilize slopes, for soldier pile and lagging, and tieback anchors.
The holes in each bit allow the grout/drilling solution to flow as the SDA is advanced, simultaneously creating the column.
Magnacore has a full line of hollow bars anchor rods to meet your project’s needs including:
Our standard stock length of bar are 4.92 ft (1.5 m) and 9.84 ft (3 m). The standard bar is non-galvanized. Galvanized bars can be ordered custom.
Special orders can be placed for custom bar lengths, sizes, and bit sizes.
