Lithonplus Steinmanufaktur, Germany, teamed up with Tecnocom for their new production method to manufacture L-shaped retaining walls. The new patented way to produce the “L-Tec System Angle” took five years of development but leads to a high quality precast element. Beside the fact that the production is now automated the finished product itself offers advantages such as easier handling, quick installation and a high-quality shape without any conicity but constant width over their entire height.
