Magnacore Micropile Self-Drilling Anchors & Hollow Bar Systems
Deep foundation work rarely goes to plan when crews hit collapsing soils, high groundwater, restricted access, or low overhead clearance, and conventional piling methods can stall in exactly those conditions. Magnacore self-drilling anchors and hollow bar systems from Intech Anchoring Systems give contractors and engineers a single-operation solution engineered for difficult ground, combining drilling, grouting, and reinforcement into one continuous pass.
Backed by deep inventory, equipment options, and hands-on engineering support, Magnacore hollow bar micropiles help project teams keep demanding foundations moving on schedule.

One System That Drills, Grouts, and Reinforces in a Single Pass
The defining advantage of the Magnacore system is efficiency. Conventional micropile methods often require pre-drilling, casing, and separate grouting and reinforcement steps, each adding time, equipment, and points of failure to a project. Magnacore self-drilling anchors collapse those stages into one continuous operation, drilling and grouting simultaneously so a completed, reinforced element is left in the ground in a single advance.
The performance keeps pace with the speed. Magnacore hollow bar micropiles achieve high load capacities and carry both compression and tension loads, making them suitable across a wide range of deep foundation and earth retention applications. Because grout is injected throughout installation, it encases the bar along its entire length, delivering corrosion protection as well as structural bond.
How Magnacore Self-Drilling Anchors Work
Magnacore anchors advance into the ground using a sacrificial drill bit threaded onto a continuously threaded hollow steel bar. As drilling progresses, cement grout is pumped through the hollow center of the bar and out through the bit, flushing cuttings, filling the surrounding void, and bonding the element to the soil in one motion.
The bar itself stays in place as permanent structural reinforcement, so a single pass produces a finished, load-bearing foundation element. For a deeper look at the mechanics and specifications, our hollow bar micropiles page covers the system in detail.
The Magnacore Hollow Bar System: One Technology, Many Applications
The same self-drilling hollow bar technology that makes Magnacore effective for micropiles adapts to a broad set of deep foundation and ground stabilization roles. That versatility lets a single, familiar system solve problems across the full scope of a project.
- Hollow bar micropiles: High-capacity deep foundations support for new construction, towers, and bridges where dependable load transfer is required.
- Underpinning and foundation repair: A proven option among the types of underpinning used to stabilize structures experiencing settlement or movement.
- Hollow bar tieback anchors: Earth retention and excavation support delivered through tieback anchors that install quickly in variable ground.
- Soil nails: Slope stabilization and retaining structures reinforced with self-drilling soil nails.
- Limited-access foundations: Foundation piles installed where headroom is tight or standard rigs cannot reach, without the multi-step process conventional systems demand.

Engineering and Equipment Support Built Around Your Project
Choosing the right micropile system takes more than pulling a product off a shelf, and this is where Intech sets itself apart. We are a supplier and technical partner rather than an installer, and our geotechnical engineers work alongside contractors, estimators, and project teams to match bar sizes, lengths, and configurations to real load requirements, soil conditions, and budgets.
The support extends to the tools and the timeline. Contractors can rent or buy the drilling and grouting equipment a Magnacore project calls for, so you are not forced to purchase gear for a single job. Deep inventory means that if you need to buy micropiles for one project or supply an entire program of foundation piles, the product is on hand to reduce lead times.
Frequently Asked Questions About Magnacore Hollow Bar Systems
Do Magnacore self-drilling anchors offer corrosion protection?
Yes, the grout injected throughout installation encases the steel bar along its full length, providing corrosion protection in addition to structural bond.
Can Magnacore be used for both temporary and permanent applications?
Yes, hollow bar systems are specified for temporary work like excavation shoring and tiebacks as well as for permanent foundations and retention.
What equipment is needed to install self-drilling anchors?
Installation uses a drill rig capable of rotary percussion paired with a grout pump, along with the couplers, bits, and accessories the system requires.
How do hollow bar micropiles compare to helical piles?
Self-drilling anchors perform best in hard, rocky, or highly variable soils and in limited-access sites, since they drill and grout in a single pass.
Can Intech help size and select the right Magnacore system for my project?
Yes, and it is a core part of what we do. Our geotechnical engineers help evaluate loads, soil conditions, and project constraints, then recommend the bar sizes and configurations that fit your requirements.
Why Contractors Choose Intech Anchoring Systems for Hollow Bar Systems
Since 1998, Intech Anchoring Systems has focused on helping deep foundation and geotechnical contractors complete demanding projects with quality products and knowledgeable support. That focus shows in our deep product inventory, which keeps Magnacore hollow bar micropiles and related systems available with short lead times, and in the geotechnical engineers who back every order with real technical guidance rather than just a price. Contractors return to us because we function as a partner on the project, not simply a source of material.
That partnership continues well past the sale, through equipment solutions, installation training, and responsive support when questions come up in the field. It is the combination of dependable products, engineering expertise, and a genuine investment in our customers’ success that has built our reputation across the deep foundation industry.
