Use this CSI 3 part SimpleSpecs™ master specification to specify interior natural stone flooring and associated bases.


Stone may be either thin or thickset. A thick setting is used over irregular substrates where the thick setting bed can level the stone. A thick setting is also used where slope must be built into the setting bed.


Special setting materials and methods are included for large and heavy stones.


A waterproof membrane is recommended where plumbing leaks could occur over occupied spaces.


A crack isolation membrane prevents cracks and joints in the substrate from telescoping through the stone.


Sound isolation membranes are used under-stone where sound transfer to a lower floor must be reduced, such as in hotels.


For assistance in selecting and detailing stone flooring to refer to the  Handbook for Ceramic, Glass, and Stone Tile Installation by the Tile Council of North America (TCNA), available at www.tileusa.com.

Stone Flooring

The SimpleSpecs™ master specs concept
Adding More Words Does Not Make Specifications More Enforceable.    
Design professionals are accustomed to seeing lengthy project specifications, so why is SimpleSpecs™ so short?
Specifications have grown evermore wordy over the years for several reasons:
  1. The mistaken belief that specifications must be lengthy and legal-sounding to be enforceable.  In fact, quite the opposite is true.  Having shorter, easily understood specifications makes us less likely to have problems in the field.
  2. A belief that having lots of words protects us from a Contactor making mistakes.  There is no way to include enough statements to protect yourself from a bad contractor, regardless of the length of your specification.
  3. Our desire to be in control of the project by specifying means and methods instead of including simple, enforceable statements.
Easier to Edit

SimpleSpecs™ is written as a series of Microsoft word files that include statements that affect construction costs or overall quality and are far simpler to edit than other master specification systems.


Each SimpleSpecs™ specification section is non-proprietary and includes three manufacturers that meet the specified reference standards, descriptive, or performance-based requirements. They are written to allow any listed manufacturers to provide the specified products.

Hidden Guide Text

Each SimpleSpecs™ specification section includes hidden text to inform and guide users in editing the specifications to suit project conditions.

Streamlined Editing

SimpleSpecs™ sections are edited using pre-defined options that are contained in [brackets] or by selecting optional text separated by "OR" statements. Paragraph and page numbering are included as automatic codes, eliminating the need to renumber when revisions are made manually.  Global changes to headers, footer, terms, font colors and phrases are easily updated using a third-party search and replace software, available through ZeroDocs.com.
