Solutions Pile Capabilities Applications Helical Piers A steel shaft with round helix plates that provides a foundation support for various types of structures. Resistance Piers Hydraulically driven sections of steel pipe that can be driven through unstable soil into load bearing strata. Underpinning The process of strengthening and stabilizing ar home or structure's foundation. Tie-Backs Commonly used along with other retaining systems to provide additional stability to cantilevered retaining walls. Micropiles Deep foundation elements constructed using high-strength, small-diameter steel casing and/or threaded bar. Sheet Piling Sections of sheet materials with interlocking edges driven into the ground to provide earth retention and excavation support. Boardwalks Installed to access sensitive areas requiring minimal disturbance, or walkways exposed to flooding and storm surges. Load Testing A geotechnical investigation to determine the bearing capacity of deep foundations prior to the construction of a building or structure.
