New CSDA standard and best practice documents for polished concrete

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.
