Segmented Sub-Horizontal Displacement Drain System

Solving Hydrostatic pressure relief & stability for soil embankments

Perforated pipe sections are coupled with a special designed open annulus coupling capable of receiving a well screen sized for a particular application while resisting the torque necessary for proper installation. Each section is perforated to allow the maximum water intake while maintaining the structural integrity of the system during installation and its performance.

The strength of the soil and/or minimum depth are determining factors for the drain system to reach its specified position within the soil matrix. Currently, the HydroHelical product is manufactured in 7 foot lengths to accommodate LTL shipping standards.
