Magnacore Tieback Anchor

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.

Tieback and anchoring systems from Intech Anchoring are hollow, threaded, steel rods that can extend to any length in all soil and rock conditions to meet your project needs. The Intech Anchoring Magnacore® system is utilized to stabilize slopes, foundations, and structures at shallow or deep depths. This is a quick installation that combines drilling, placing, and grouting in one operation. This allows the system to be suitable for working in a limited space.

By utilizing Magnacore SDA’s for Tiebacks, you can save time and money with quick, efficient, all-in-one installation. Magnacore has high production capabilities, with minimal vibration or displacement of soil during installation. You can determine instant load capacity and continuously monitor torque with Magnacore Tiebacks. Because of Magnacore’s unique design, they can be used as earth shoring in areas of limited access.

Solid Bar versus Hollow Bar Anchors

Solid Bar

  • Predrilling required
  • Limited to shallow rock
  • Very stiff throughout soil strata
  • Casing needed in soft soils
  • Pre/Post grouting required
  • Several pieces of equipment

Magnacore Tieback Hollow Bar Achor

  • Rock at any depth
  • Can be installed in all soil types
  • Casing for lateral loads
  • Grouting completed during install
  • Only need rock drill & grout plant

Tieback Anchor Sacrificial Bits

The holes in each bit allow the grout/drilling solution to flow as the SDA is advanced, simultaneously creating the column.

  • Tungsten Carbide Button Bit for hard rock (Limestone, shale)
  • Tungsten Carbide Cross Cut Bit for softer rock (sandstone, soft shale, or fractured rock)
  • Clay Bit ideal for mixed fills and clay
