Patent ID: 7900576

Claim:
A system for treating and consolidating with hardenable resins monolithic or multi-layer stone blocks, the blocks comprising a plurality of stone layers, the system comprising: a) one or more than one liquid-tight and gas-tight sheet forming a containing housing of a block, wherein the containing housing comprises an interior; b) one or more than one resin-permeable layer arranged between the block and the sheet creating a space between the block and the sheet, wherein hardenable resin can flow through the layer; c) one or more than one closing manifold comprising a central body and a cover, wherein the closing manifold further comprising connecting means connecting the interior of the containing housing with one or more than one pressure control duct, wherein one or more than one of the pressure control ducts is connected to a first vacuum pump, wherein the one or more than one closing manifold further comprises one or more than one air inserting duct inside the containing housing and sealingly passing means of one or more than one resin supplying duct supplied with resin by a resin storing, conditioning and mixing means; and d) an autoclave comprising one or more than one supporting platform of the block wrapped in the resin-permeable layer and in the sheet; and wherein the containing housing which contains the block and the autoclave defines two different and separate environments which communicate with each other to keep a pressure in the containing housing lower than a pressure in the autoclave for counteracting a hydrostatic pressure of the resin inserted in the containing housing and pressing the sheet against the block.
