Profile: Matvey Construction, Inc. specializes in providing foundation repair services for commercial, industrial and municipal applications. Our helical wall anchors include a long rod and a corkscrew-like helical shaft that mounts to the wall plate on the inside of the foundation walls. Large holes must be drilled in the wall during the installation process. The helical anchors are installed and anchored into the soil. Once the helical anchor is in place, the hole is refilled with concrete, and a wall plate is installed over the top. Helical piles are a factory-manufactured steel foundation system consisting of a central shaft with one or more helix-shaped bearing plates welded to the lead section. Brackets are used at the top of the piles for attachment to structures, either for new construction or retrofit applications. Helical piles are screwed into the ground with the application of torque. Helical piles are designed such that most of the axial capacity of the pile is generated through bearing of the helix blades against the soil. Helical anchors can be installed with hand-held equipment, mini-excavators, skid steers, backhoes, trackhoes, or crane-supported rigs.
