Drainage Blanket

The stabilisation of embankments, often in excavations with water infiltration, is treated with drainage blankets comprising a geotextile filter with rockfill on top.

The teracro® TD geocellular structure is the efficient, economical alternative. It allows the site materials to be re-used and ensures retention and drainage.
