Stone Restoration

During renewal jobs on old historic buildings, we are regularly face with stone restoration tasks.

Natural stone is the raw material of figurative ornaments: shields, statues, chalices, gate frames, capping stones and stairs.

Execution of the job itself is always preceded by diagnostics, and the restorer’s expertise is indispensible.

Mechanically damaged or crumbled surfaces are moved mechanically or with a machine applying TORBO technology. The TORBO method is a surface clearing procedure that exploits low-pressure-pot water cleaning or granule blasting to demolish eroded surfaces and layers with great care using rubbing movements.

The process of restoring and finishing material is always led by a trained restorer and implemented with stone-supplementing mortars. Colouring, tarnishing and impregnation of surfaces normally make up the last phase of the work.
