Helical Pile Contractor Toronto

Zetta Construction is proud to use CHANCE® products for new foundation systems, for new deep foundations helical piers are installed at intervals between the footing forms and tie into the rebar gridwork prior to pouring concrete.

Advantages of helical piles

  • Quick installation and can be loaded immediately upon completion
  • Can be modified in the field
  •  Reach competent soil below active zone
  • Predictable via torque-to-capacity ratio
  • No excavation or spoils to remove
  • Installs in limited access
  • Installs in any weather condition
  • Loads may be immediately applied
  • Installs in limited access

Zetta can support a wide range of commercial, industrial, institutional and residential structures. We provide the expertise and support to assist geotechnical and structural engineers in designing and constructing deep foundations and specialty shoring systems. We utilize helical piers and micropiles to resist compression, tension and lateral loads.

Helical piles and micropiles can be utilized for new foundations from light to heavily loaded structures in densely populated residential areas, congested business areas and easily accessible construction sites.

Foundation Repair and Augmentation Systems for Residential, Commercial and Industrial applications

For stabilizing/lifting foundations or retrofitting to increase load capacity, CHANCE® steel piers are installed at intervals around the perimeter at affected locations. Independent of the structure, the piers are extended to depths which attain the installing torque correlated to the required load bearing capacity. Special brackets are located where needed around the perimeter and secured to the concrete foundation. Then a steel pier is torqued into the soil through each bracket. The brackets permit lifting by hydraulic jacks. Tightening the nuts on the bracket vertical bolts locks off the load.

 

In a soil nail application, the Soil Screw® Retention Wall System constructs a gravity wall to reinforce in-situ soil with screw anchors nearly horizontal. Anchor sizes and grid spacing are determined by soil conditions and load requirements. A reinforced shotcrete veneer often is applied to the face.

To remove the performance uncertainties and associated costs of grouted soil nails in soils of low shear strength, a Soil Screw® anchor acts as a bearing device. This load-bearing mode is its fundamental superiority compared to a grouted anchor which relies on friction between the soil and the grout.


Zetta is equipped with TORQ-PIN a monitoring and data logging system that can fit any type of drive head. Where conventional differential hydraulic pressure readings can be 30 – 50% out, the TORQ-PIN monitoring system offers true torque readings that are 98%+ accurate! There is absolutely no loss of boom height which give us better access on low headroom spots.
