A sealed and thermally insulating tank for storing fluid has a wall including a supporting structure, a primary thermal insulation barrier and a primary sealing membrane lying against the primary thermal insulation barrier, contacting the stored fluid. The primary thermal insulation barrier includes a primary insulating panel which includes a bearing zone collaborating with an anchoring device bearing against the bearing zone of the external rigid plate holding it toward the supporting structure. The primary thermal insulation barrier includes a reinforcing insulating plug extending, in the thickness direction, from the bearing zone of the external rigid plate to a specific zone of the primary sealing membrane to take up the compressive forces on the specific zone of the primary sealing membrane. The reinforcing insulating plug includes a polymer foam layer having a compressive yield strength greater than that of the polymer foam layer of the primary insulating panel.
