- "Through the miracle of modern technology, this mill allows you to turn Stone into Blocks."
- — In-game Description
The Concrete Plant allows you to process Stone into Concrete, at an exchange rate of 2 for 1. Concrete is necessary for building more advanced structures which become available once you reach Level 15. This is also the focus of the mission A Concrete Plan.
The Adv. Concrete Plant produces concrete more efficiently and faster. Most players consider it worth the cost.
To maximize production, place your buildings where visitors (friends) will see them immediately when they open your world. This makes its easy for them to help you. Player should also consider building multiple Concrete Plants for increased production rates.
