Sandberg offers a comprehensive building stone consultancy service covering all aspects of selection, evaluation and quality, from initial source evaluation through testing and suitability to on-site inspection and verification during installation.

Technical appraisal of natural stone for both internal and external cladding systems and decorative surface applications (eg tiling and flooring) can be provided. Expert consultancy advice is offered on the suitability of material, especially with respect to long-term durability or in-service characteristics such as slip resistance of floors.
