Abstract:
A method for consolidating a block of natural stone or recomposed material having fractures and internal cavities, the block having a bottom, side walls and a top, the method comprising the steps of:wrapping the side walls and bottom of the block to be consolidated with an impermeable sheath having spacers facing the side walls and bottom to define a free space between the sheath and the block; placing the block with the sheath thereon, in an autoclave; applying a vacuum to the autoclave so that the free spacer is exposed to vacuum; applying a fluid hardenable resin into the free space being exposed to the vacuum; thereafter removing vacuum from the autoclave so that rising pressure in the autoclave forces the resin to penetrate the fractures and internal cavities of the block; and allowing or inducing the resin to harden to consolidate the block.
