Deep Foundations

Deep Foundations Solutions

Deep foundations services transfer structural loads through to competent soils or rock when shallow foundations are not feasible due to weak, compressible soils near the ground surface. Micropiles, helical piers and underpinning, driven piles, and pulldown Micropiles are deep foundations elements.

Intech Anchoring has experience with a full range of deep foundations repair services, techniques, and products to provide the most cost-efficient and technically appropriate solution for any deep foundations project. We have relationships with multiple manufacturers to provide the best solution for your situation.

Micropiles (also referred to as mini-piles) are deep foundations, small diameter grouted piles typically consisting of a central steel reinforcement member and commonly includes steel casing. They are designed to carry very high capacity loads.

Unlike a drilled pier, micropiles derive a large percentage of their load from the steel reinforcement. This, paired with achieving their load in skin friction, makes micropiles perfect for both tension and compression loads.

Micropiles can be used on a variety of projects, including the creation or fortification of foundations for bridges, towers, and new buildings. Their versatility has led to their increased popularity and their use in difficult construction conditions such as in areas of low clearance, restricted access, or collapsing soil types.

Compared to other foundation products, micropiles are customizable and cost-efficient because they eliminate the need for pre-drilling during installation.

Intech Anchoring offers a variety of projects for micropile system installation, including Magnacore SDA’s, and CHANCE Anchors.

The helical pulldown micropile (HPM) is a system for constructing a grout column around the shaft of a standard helical pile foundation system. The HPM does not require removing spoils from the site. By combining both end-bearing on the helical plates and skin friction along the rough surface of the grout column, the result is a higher capacity pile system.

The HPM brings the advantages of the pre-engineered helical pile to higher load applications. It can provide an additional 50-100% capacity when compared to an ungrouted helical pier in similar soil conditions.

By “pulling down” a flowable, expansive grout as the foundation is screwed into the soil, the micropiles create a deep foundations with a friction-bearing central shaft and end-bearing helical plates in competent substrata.

Other benefits of HPM include:

  • Speed: 40-50 piles per day / per crew
  • High capacity
  • Cost-effective
  • No pre-drilling
  • Resistance to buckling in weak soils

Micropile Applications

Helical Piers And Underpinning

To reverse the signs of a sinking foundation, the most effective way is to use a process called underpinning—also known as piering or piling. There are many piering systems available, but the most effective solution is to transfer the weight of your home to a more stable soil than the soil it is currently resting on.

Helical piers contain helices that serve as end-bearing plates for the weight of the house. The flights are welded to a central steel shaft that acts as a screw that is rotated into the soil.

Helical piers are used to secure many structures:

Hollow Bar Micropiles

Because drilling, grouting, and installation happen simultaneously, hollow bar micropiling requires no pre-drilling or pre-/post-grouting, not only reducing the number of steps but also the amount of equipment needed for installation.

A rock drill and grout plant are generally all that’s required for hollow bar micropiling. Even with less equipment, however, it’s still possible to maximize micropile strength by increasing grout pressure to enlarge pile diameter.
