MacLeanCivil offers a broad range of steel foundation piles used to support walkways and boardwalks in environmental sensitive areas.  These piles can be installed to permit wildlife to pass underneath the raised walkway.  No roadway is required and minimum disturbance to the environment during construction. We offer many time proven solutions with experience in anchoring since the 1920's.  It is important the product and installation meets stringent requirements to insure the quality and workmanship of the manufactured product and installation is performed by qualified and certified technicians to insure the foundation will perform as expected.

Helical foundation piles are installed by rotating into the soil using manual, portable or other suitable equipment.  A bracket is added to the installed pile and the walkway or boardwalk sections are placed on top of the installed pile bracket.

MacLeanCivil has qualified relevant products to meet the IBC (International  Building Codes) ICC AC358 Acceptance Criteria for Helical Foundation Systems and Devices.  This should be an important criteria when selecting the supplier to protect your investment for years to come.

A typical helical pile for a walkway application consists of a 1) lead, 2) one or more extensions and 3) a bracket to support the walkway.

The lead is either a solid round corner square shaft or pipe with one or more helices or circular plates welded to the shaft.  The helices provide the bearing area to support the structure.  The shaft type and size and length are determined by the soil, installation depth and structure load requirement.  The lead is installed with a variety of hydraulic torque motor equipment.  The lead (similar to installing a wood screw into wood) is rotated vertically into the soil to a suitable depth until competent soil is reached to develop the required load bearing capacity.

The location, number and type of helical foundation piles are selected by the engineer or certified MacLeanCivil Distributor or installer.  Torque monitoring by a certified MacLeanCivil installer assures each helical pile is installed to the required specification.

Extensions are used to advance the lead to whatever depth is required.  The total installed depth may range from near the walkway bottom to 50 or more feet.
