Concrete foundations require specialized machinery to process, transport, pour, and level and a large team to carry it all out. But Helical piles don’t require any specialized machinery to install, and the installation can be carried out by a small crew.
Any service or repair that a concrete foundation requires will call for the same specialized machinery and energy output that the installation required. But due to their size and design, helical piles can easily be replaced, repaired, expanded, or removed using simple machinery and techniques.
Concrete can be reused, but the act of removing old concrete and processing it into reusable concrete involves massive carbon emissions from the same specialized machinery. But Helical piles can be removed and refurbished, and reused as foundations at other worksites, without the massive impact of the concrete carbon footprint.
