New style prefabricated drainage tile
We've come up with a new-style prefabricated drainage tile that does the job of expensive stone aggregate drainage with the ease of installation of plastic tile. It uses expanded plastic aggregate that's light-weight, eliminating the need for heavy equipment to transport stone. It consists of a -conventional plastic drainpipe surrounded by 3 in. of expanded polystyrene aggregate, which varies in size-from 3/4 to 2 1/2 in. in dia. Comes in 10-ft. sections that can be bent around corners. The plastic aggregate lets water through while restricting soil par-tides. No clogging occurs. Moisture retention and flow are equal to or better than stone. It's designed for drainage of farm fields, wetlands, golf courses, and can be used for septic drainage fields.
