Studioverket has created the Subterranean Concrete Orgy. All panels were made by pressing concrete in-between two layers of Sealed-Air bubble. High strength EXM concrete is used. The leaf-thin layers of concrete – where bubbles have connected, can either be removed for transparency or be kept for translucency. In case of vegetation, mineral substrate is held in place behind the panel and the created sandwich is watered by a dripping hose at the top.
