Today's land developers are being forced to find new ways to manage storm water runoff, largely because of increasingly stringent regulations and skyrocketing land values. Hancor's LandMax storm water pipe system provides the ideal solution for efficient, effective subsurface storm water retention and detention.

  • For maximum design flexibility, the LandMax HDPE pipe system utilizes Hancor products that offer complete compatibility- including Sure-Lok® ST, and BLUE SEAL® complemented by a wide selection of fittings, joints, couplers and adapters.
  • Providing high strength without excessive weight, LandMax high density polyethylene (HDPE) components allow easy handling and fast assembly. The end result is construction schedule compression.
  • Installed below grade, LandMax subsurface retention/detention systems increase the usable land available, providing space for parking lots, playgrounds and other facilities to be built on top.
  • Completely inaccessible to the general public, LandMax systems decrease the safety risks and added costs associated with open ponds.

LandMax System Specifics

Hancor's LandMax system is comprised of Sure-Lok ST and/or BLUE SEAL bell-and-spigot HDPE pipe, with standard or custom-made header systems and fittings. The product is available perforated or non-perforated, and all components are installed below grade, meaning that parking lots or other facilities can be built right on top of them.

Hancor manufactures HDPE pipe in diameters up to 60", making our system one of the most versatile subsurface retention and detention systems available. What's more, Hancor offers technical support to assist you in specifying, designing, and value engineering LandMax systems.
