Technical Letters

Technical Letters Quality Assurance Product Performance Third Party Verification Tile and Natural Stone

Although we reference sections of industry standards and guidelines in our email responses, sometimes a technical letter is needed on company letterhead to provide an official stance or explanation of standards to your clients when an email just won't do. The advantage of going with Riata Group's Letter Writing services is that we are a reputable third party organization that can verify and provide complete and accurate industry information without any bias towards the situation or parties involved.

Technical letters can include by way of example but without limitation to statements on:
  • Out of square tolerances for tile and stone
  • Allowable lippage allowance
  • OSHA respirable silica standards
  • Use of a particular product in a commercial/residential application
  • Sanitary covebase requirements where a health code exists
  • Warping tolerances
  •        Pattern offset and grout joint width recommendations by product type
  •        Calibers and shade lots - coordinating trim, patterns, reorders
  •        Raw ingredient information
  •        Slip resistance- DCOF and SCOF
