A system (10) is disclosed for treating and consolidating with hard-enable resins stone blocks (1) comprising at least one liquid- and gas-tight sheet (2) adapted to form a containing housing (3) of a block (1); at least one permeable layer to the resin arranged between the block (1) and the sheet (2) adapted to create a distance between the block (1) and the sheet (2) through which resin can flow; at least one closing manifold (20), comprising a central body (5) and a cover (6), such closing manifold (20) being equipped with connecting means adapted to connect the interior of the containing housing (3) to at least one pressure control duct, at least one duct (15) connected to a first vacuum pump (21), at least one air inserting duct (19) inside the containing housing (3) and sealingly passing means of at least one resin supplying duct (17) supplied by resin storing, conditioning and mixing means; and an autoclave (13). A process using the system is further disclosed.
