Magnacore® Self-Drilling Anchors
Intech Anchoring supplies contractors with the industry-leading Magnacore® Self-Drilling Anchor (SDA). Magnacore® is a hollow bar injection-bore micropile that serves as an economical solution for challenging soil conditions. Installing conventional Micropiles may not be the best option in situations with collapsible soils, large boulders, or other obstructions. The self-drilling anchor allows for placing, open hole drilling, and grouting in an all-in-one installation.
The Micropile is formed in a single, top-down operation by the injection of a high-pressure, neat cement grout mixture. The mixture is pumped through the bar and serves as the drill string. The neat grout mix exits through 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.
In addition to outperforming other anchoring systems on the market today, Magnacore puts money back into the pocket of the contractor. The material cost comparison of Magnacore®and other hollow bar micropiles is unmatched.
Because of its unique all-in-one installation process, contractors can save on labor costs, as fewer rig operators are required. Installation is a timely process, which saves on hourly wages.
