Quality Assurance

>>>Tips for choosing a terrazzo contractor

To assure your client of a quality Terrazzo installation, we suggest that you consider the following when specifying Terrazzo:

The National Terrazzo & Mosaic Association consists of Terrazzo contractors and suppliers. These members must meet specific requirements for membership in this Association, as identified in the specifications that follow:

QUALITY ASSURANCE
  • Acceptable Supplier:
    • Suppliers shall provide materials in accordance with the NTMA standards.
  • Acceptable Installer:
    • Installer shall be a contractor member of NTMA or
    • The installer must be pre-qualified by the architect by submitting a list of five projects completed in the last two years of similar magnitude and complexity.
When NTMA specifications are included in the bidding document, it is assumed that the specifier's intent is that all work be executed in accordance with those specifications. Caution: Since not all Terrazzo contractors or suppliers elect to be part of the NTMA or follow the guide specifications, their actions are beyond the control of this Association.
