Secant Forms

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.

Benefits of Secant Forms


As time progresses, construction businesses, architects, and engineers are gravitating toward geofoam as it is easy to work with, affordable, and requires a minimal time investment. In fact, it merely takes a couple of workers to move a large block of geofoam by hand. This is much more efficient than investing the time and effort necessary to fill the area with soil. In fact, the use of geofoam for roadbed or embankment support prevents the need for heavy construction.

Waterproof Membrane

Geofoam is also favored as there is minimal disturbance to the land along the exterior of the foundation. Geofoam is water-resistant, easy to put into perfect position and built to last. Secant pile wall construction with geofoam will be used in more and more civil engineering projects with embedded retaining walls. Geofoam facilities the stabilization of embankments basements and other storage spaces.

Long-term Stability

Furthermore, geofoam helps create secant walls that stabilize and protect subterranean tanks as well as other buried structures. As long as the groundwater table location, deflections, propping, soil conditions and other factors are reviewed appropriately beforehand, geofoam will prove optimal for secant wall construction.
