<p>Vacuum resin process for marble blocks in bags of flexible plastic material, covering the blocks with a draining layer for the resin with a series of gaps over the entire surface of the block inside which the resin can spread. A further covering with one or more layers of glass fibre (or similar)fabric aims at protecting the plastic bag from holes and ensuring a great mechanical resistance of the hard resin. The vacuum condition inside the bag lets the resin flow in all the gaps formed by the draining layer between the block and the plastic bag, so the resin can fill all the surfaces of the block and the glass fibre fabric. This process has the advantage to get a perfect penetration of the resin into all the pores and cavities of the marble block using as few resin as possible, and to get a structural protection around the block, perfectly made cohesive, permitting to cut even blocks of minor quality without any risk of breaking them.</p> |
