Building Stone Existing Structures
Expertise is offered in stone consultancy by the Sandberg Consultancy Department to inspect, investigate and advise on remediation techniques to restore natural stone both externally and internally on structures.
Stone consultancy is UKAS accredited and testing is performed in-house to National and International Standards.
In-service failures of stone are not uncommon due to inherent natural characteristics, poor production methods or the fact that the material is unsuitable for its intended purpose. Typical failures, whilst not necessarily structurally damaging, can cause unsightly appearance or lead to personal injury. Examples include differential porosity/absorption, staining, high wear/abrasion of flooring, reduction in slip resistance and step edge failures.
Stone consultancy services include:
- Condition surveys
- Failure investigations
- roof tiles
- floor abrasion
- crack detection - fluorescence techniques
- Stone selection / Quarry evaluations
- matching for repairs
- colour uniformity
- grain consistency
- weathering characteristics
- Physical testing
- Durability testing
- Chemical analysis
- Cleaning method evaluations
- Restoration technique trials
- Expert witness/litigation reports
The appearance and careful restoration of natural stone, particularly to historic building facades and floors, is of great significance and importance both aesthetically and structurally.
