Product information

Product name

Ram Jack Helical Foundation Systems and Devices

Product description

The products consist of a lead (shaft) section with helical-shaped blades that have an extension with or without helical blades. The lead section and the corresponding extension consist of a 73 mm or an 89 mm outside diameter steel pipe that has a nominal wall thickness of 5.51 mm or 6.35 mm, respectively.

The lead and extension sections are connected by a solid internally threaded pin and box connection that is welded on the trailing end of the lead section and each end of the extension. Helical-shaped blades that are shop welded to the shaft advance the pile into the soil when rotated. The helical blades are 203 mm, 254 mm, 305 mm or 356 mm in diameter and are 9.5 mm or 12.7 mm thick. The helical blades are pressed using a hydraulic press and die to achieve a 76-mm pitch prior to being welded to the lead (shaft) section.

The lead shaft and extensions are coated with a polyethylene copolymer coating with a minimum coating thickness of 0.46 mm.

  Conditions and limitations

The CCMC’s compliance opinion is bound by this product being used in accordance with the conditions and limitations set out below.

  • The product under this evaluation is intended to be used as a foundation system to support the following types of construction:
    • Single storey residential buildings within the scope of Part 9 of NBC 2015;
    • Accessory buildings such as sheds, gazebos, sunrooms, carports, and decks/porches within the scope of Part 9 of NBC 2015.

    Other applications are beyond the scope of this evaluation, wherein a professional engineer skilled in such design and licensed to practice under the appropriate provincial or territorial legislation must determine the pile capacity and other design parameters.

  • The product may be used as a foundation system to support various constructions provided that it is installed according to the manufacturer’s current instructions and within the scope of this Evaluation Report.
  • Where the product is installed in granular soil or silt, there is a direct relationship between the applied torque and the allowable compressive loads, which are indicated in the tables:
  • Where the product is installed in a cohesive soil such as clay, the relationship between the applied torque and the allowable compressive load is not predictable; as such, the allowable compressive loads must be confirmed by on-site load tests. These load tests are also required if the allowable loads exceed those stated in the tables under the Technical information section. The tests must be conducted under the direct supervision of a professional geotechnical engineer skilled in such design and licensed to practice under the appropriate provincial or territorial legislation.
  • In all cases, a registered professional engineer skilled in such design and licensed to practice under the appropriate provincial or territorial legislation must determine the number and spacing of the auger-installed steel piles required to carry all the loads. A certificate attesting to the conformity of the installation and the allowable loads for the piles must be provided.
  • All welding is to be done by welders that are certified.
  • Where conditions (soil and environmental) are determined to be corrosive to steel, protection of the steel shall be provided. The determination of the presence of corrosive conditions and the specification of the corrosion protection shall be carried out by a registered professional engineer licensed to practice under the appropriate provincial or territorial legislation”. If the determination of the presence of corrosive conditions is not completed before installation, the product, including all its accessories, is required to be hot-dipped galvanized, meeting the requirements of CAN/CSA-G164 (ASTM A123/A123M-17) with a minimum thickness of 610 g/m2, or another method that provides an equivalent level of protection and abrasion resistance deemed acceptable by CCMC.
  • The installer must be certified by Ram Jack Distribution Systems to be permitted to install the product. The installer must follow the manufacturer’s installation instructions, use approved equipment, and heed the uses and limitations specified in this Report. Each installer must carry a certification card with their signature and photograph.
  • Each product of auger-installed steel pile must be identified with a label containing the manufacturer’s identification and the phrase “CCMC 14039-R.”

CCMC-TG-316615.13-15ACCMC Technical Guide for Augered-Installed Steel Piles

General

Ram Jack Distribution Systems provide the products in diameters of 73 mm or 89 mm. The piles were tested in accordance with:

  • ASTM D1143-81(1994)e1, “Standard Test Method for Piles under Static Axial Compressive Load,” and
  • ASTM D3689-90(1995), “Standard Test Method for Individual Piles Under Static Axial Tensile Load.”

The installation torque is directly used to calculate the allowable bearing capacity of the pile by applying the direct correlation method. For the allowable compressive and tensile loads noted in the tables below, the factor of safety is 2.

The protective coating used on the piles was also tested; it performed well during the tests.
