Why Porosity Inhibiting Admixtures (PIA’s) Outperform Moisture Vapor Reduction Admixtures (MVRA’s) (Article 803)

Porosity Inhibiting Admixture (PIA)

  • PIA inhibits and stops the redistribution of concrete moisture in slab-on-grade and elevated deck applications. Effectively, eliminating the main source and/or cause of interior flooring adhesive failures.
    • PIA incorporates a project specific five-point quality control program that consist of (1) project warranty registration, (2) reviewing and approving all concrete mix designs that require PIA, (3) daily ASTM D-5084 onsite permeability testing, (4) photo verification of a ASTM E-1745 Vapor Retarder properly installed via ASTM E-1643, and (5) confirmation of positive “bond test” to enhance project specific warranty.
      • PIA encapsulates all of the sustainability and performance features cultivated through our Concrete Enhancement Technology® (CET) Research and Development Program.
        • PIA is recommended for inclusion in all buildings that are specified to have flooring systems adhered to concrete subfloors, projects with aggressive schedules, and projects with limited budgets for last minute change orders.
          • PIA Technology is 10-times less permeable (more effective) than MVRA Technology, and sodium silicate free.

Moisture Vapor Reduction Admixture (MVRA-CPS)

  • MVRA-CPS reduces the redistribution of concrete moisture in slab-on-grade and elevated deck applications. Effectively, weakening the main source and/or cause of interior flooring adhesive failures.
  • MVRA-CPS incorporates a project specific four-point quality control program that consist of (1) project warranty registration, (2) reviewing and approving all concrete mix designs that require MVRA-CPS, (3) photo verification of a ASTM E-1745 Vapor Retarder properly installed via ASTM E-1643, and (4) confirmation of positive “bond test” to enhance project specific warranty.
  • MVRA-CPS, at differing levels, encapsulates all of the sustainability and performance features cultivated through our Concrete Enhancement Technology® (CET) Research and Development Program.
  • MVRA-CPS is recommended for inclusion in all buildings that are specified to have flooring systems adhered to concrete subfloors, projects with aggressive schedules, and projects with limited budgets for last minute change orders.
  • MVRA Technology is 10-times more permeable (less effective) than PIA Technology and contains sodium silicates.
