- Moisture-resistant mineral fibre board (no plasterboard!)
Until 1850, pure brick coved vaults were still made. Between 1850 and 1910 steel girders were used for the so-called Prussian coved vault.
From 1910, basement reinforced concrete ceilings made of in-situ concrete were common.
This was followed by hand-assembled steel-brick basement ceilings. For cost reasons, floor ceilings were designed as wooden beam ceilings until 1950.
