In response to requests by architects and engineers to resolve consistency issues associated with quality levels of polished concrete surfaces, the Concrete Sawing & Drilling Association has released two technical documents — an industry standard and a Best Practice.
CSDA Standard ST-115 Measuring Concrete Micro Surface Texture uses surface texture instead of gloss to evaluate polished concrete. A collaborative effort between the CSDA Polishing and Standards & Specifications Committees, it identifies approved instrumentation for measuring surface texture and provides a benchmark measurement procedure for contractors and specifiers to follow. The document covers important steps in the production of a quality polished floor and gives useful guidelines associated with the testing and inspection of a finished concrete surface. In addition to all this, CSDA-ST-115 includes a standard process for documenting surface texture readings, a list of industry terms and definitions, and a section on codes, symbols and charts to assist concrete polishers.
The accompanying Best Practice, CSDA- BP-015 Green Polishing and Grinding Practices, has been devised to help concrete polishing and grinding contractors create a detailed plan for performing their work in a more environmentally friendly manner. It provides guidelines and recommendations for companies to employ on the job site, in the office or in the shop.
