Paper by FAASEN from ISCR 7th 1994 Vienna Austria
A cycle track had to be laid quickly on a poor load-bearing subsoil, 18 m of peat. The usual design would have caused excessive subsidence and damage to the adjacent road. The chosen solution was a "floating" structure. In the design the upward pressure of the groundwater was considered to ensure that the equilibrium was maintained. It proved possible to achieve this by using aerated concrete with a very low density in the foundation, and laying the foundation to a depth of 0.80 m below the water table.
