LUN-DRAIN™ is a prefabricated, high flow drainage system that offers better drawdown of water than pipe while costing around 50% less to install. With a crush strength of 6,000 to 9,000 psf, LUN-DRAIN'S™ core easily withstands the pressures of backfilling and compaction during installation with no loss of flow area. And the multichannel structure of the formed polyethylene core provides significantly increased water flow. The tough non-woven, needle punched polypropylene filter fabric covering prevents core clogging while allowing water entry through every inch of its surface.

LUN-DRAIN LD 30 highway edge drain consists of a single cuspaded (1 sided) polymeric core surrounded by a geotextile filter fabric. Edge drain provides a positive and rapid drainage system for water that enters the highway pavement structure. It is a low-cost, easy to install alternative to aggregate drains for both new and existing highways.

LUN-DRAIN LD 20 strip drain consists of a double cuspaded (2 sided) polymeric core surrounded by a geotextile filter fabric. The fabric allows water to pass into the core while restraining soil particles which might clog the core. The core allows water to flow to designated drain exits.
