Secant forms with geofoam are becoming more popular as time progresses
Secant walls are often constructed with rebar cages for reinforcement or I-beams. Once drilled, the secant walls form equally spaced piles and create a deep drilled foundation that is beneficial in areas where there is limited space, such as between buildings or along roadways…reducing disturbance to adjacent structures.
Poly Molding’s EPS secant forms simplify the process and reduce the cost of laying out and drilling secant walls. To make handling and installation of the forms easier, the overlapping cylinders are typically manufactured in groups of 2 or more to reduce the number of units being handled at the job site.
