The project: G5RD-CT-2000-00233

Summary
All across Europe the long term deformation of marble cladding has resulted in safety and durability problems. This has resulted in increased maintenance costs, and reduced production, exports and employment. The assessment of facades at selected study sites, using monitoring systems, risk assessment and lifetime prediction, will be used to develop hypotheses for the observed deterioration. Repair techniques will be developed for existing buildings, thus reducing maintenance costs for existing problems. Research carried out on a large number of stone types will be used to explain degradation and develop European test methods. The test methods will be used for production control and screening tests to identify good and deleterious marble and so reduce future damage and promote use of natural stone for cladding, thus improving employment and increasing European competitiveness in this area.

The project has three clear-cut objectives being:

  • To establish a sound understanding based on natural sciences of the phenomena leading to poor field performance of marble clad facades.
  • To device a test method for determination of potential bowing of thin slabs of natural stone.
  • To develop a field monitoring, evaluation and repair guide for facade cladding, which will include risk assessment and service life prediction.
