The method is for supporting and sealing an earth area involves a spigot board (10) and a sieve device (14) installed in the ground until the lower end has penetrated a ground layer (18) with reduced water permeability. Then the spigot board is withdrawn, so that a slot (19) is formed in the earth area, in which a sealing concrete suspension is injected through a tube (12). Finally, the spigot board is pressed back into the filled slot. On hardening, the concrete suspension forms a concrete surround at the lower end of the spigot board, which is connected in a sealed manner both with the surrounding earth and the spigot board. |
