DIY Gasbeton Nativity Scene: Easy Carving Guide 2026

Creating a nativity scene out of gasbeton (aerated concrete) is easier than you might think. The soft blocks of this material are even less problematic to carve than wood, having no grain or knots. Corrado Cacciaguerra shows us how it's done.

Aerated concrete blocks are now very common and you can easily find them in construction site leftovers or, at worst, buy a few at a building supply store for a negligible cost. The tools needed for the work are very simple: a wood saw with a used blade (since gasbeton quickly dulls the teeth), some knives (pointed and rounded), and a bottle of vinyl glue for finishing.

Preparation

After deciding on a height for the figures, cut a prismatic piece of appropriate dimensions from the gasbeton block. Taking inspiration from existing statues or images easily found in books and online, proportion the figure by tracing the outline with a pencil on the block.

Rough out the statuette with your saw, removing waste parts both transversely and frontally. It is preferable to use an old blade, which can still cut the soft aerated concrete, since friction quickly causes loss of sharpness.

With the knives, remove material until the desired shapes emerge. Gasbeton is very yielding, so you can sculpt either by cutting "slices" of material or by scraping the surface to obtain the smallest details.

To stabilize the surface of the statuette and prevent the concrete from crumbling during handling, immerse it in a fixing bath by mixing water and vinyl glue in equal parts. After drying for a few hours, the figure is ready to populate your nativity scene.

Cork and Sand Hut

The statuettes of this gasbeton nativity scene deserve a wide frame to highlight them properly: the cave expands to encompass the entire nativity scene with all the figures. The base is made of 10 mm plywood while the walls and vault are obtained from a single ring of cork bark, opened and trimmed as needed.
