Deep Foundations For T&D
Expertly designed, reliably driven. We are DFI, your one-stop steel piling source – and we’re proud to be your “foundation” for Transmission & Distribution infrastructure! From concept to cap, start to finish, consider it handled.
Realize the efficiency of year-round construction with steel piling, and expect a turnkey advantage when you choose DFI. We execute everything: design, civil drilling, surveying, pile manufacturing & supply, pile installation, pile testing, pile cap supply & install, and pile extraction.
T&D Piling Capabilities
DFI has the capability of providing steel piling for the following transmission and distribution applications.
Transmission Towers – To accommodate high lateral loads, we can install battered (angled) piles. In addition, we pride ourselves on the ability to install an industry leading uninterrupted pile length of 23 metres, avoiding costly splicing or bolt-together connections. Finally, our interchangeable attachments allow us to alternate between helical and driven pile applications, reducing mobilization costs.
Substations – Our proprietary line of purpose built in-house RGZ cranes can reach over existing infrastructure, which allows better access from one position and decreases the need for mobilization. Again, our interchangeable attachments allow us to alternate between helical and driven pile applications, further reducing mobilization costs.
Distribution Lines – We have the ability to install bucket piles (barrel size up to 152.4cm OD) for helical piling applications. If overhead restrictions exist we can install piles in sections. Cost savings will be realized as the helix can be shipped inside the barrel.
Circuit Breakers – We also provide sheet piling for containment pits.
