Plant Certification

Corinthian Cast Stone Inc. maintains a stringent quality control program. Our Plant personnel and field personnel have the appropriate certifications and licenses. Including the following:

  • OSHA 10 hour certification
  • NYC scaffold certification
  • NYC swing scaffold certification
  • New York State mobile laser operator’s license
  • New York State Professional Engineer
  • New York State Licensed Architect
  • WR Grace Dry Block II producer plant
  • Cast Stone Institute Certified Plant

This program is based upon:

  1. ASTM C1364 – 10b Standard Specification for Architectural Cast StoneAbstract – This specification establishes the physical requirements, sampling, testing, and visual inspection of architectural cast stone that may be made from…a homogeneous mixture, produced either by wet or dry casting. Conformances for raw materials, Portland cement, aggregates, coloring pigment, reinforcement, chemical admixtures, air entraining admixtures, water reducing and accelerating admixtures, ground slag, fly ash or natural pozzolan, and other consituents shall be precisely observed. Products shall also conform to specified physical and performance requirements such as compressive strength, cold water absorption, boiling water absorption, air content, field testing, resistance to freezing and thawing, and linear drying shrinkage.
    1. ASTM C1194 – 03 Standard Test Method for Compressive Strength of Architectural Cast StoneSignificance and Use – This test method is to be used in determining the compressive strength of cast stone. Compressive strength is one measure of resistance of cast stone to weathering and structural stress. This test method covers the sampling, preparation of specimens, and determination of the compressive strength of architectural cast stone.
    2. ASTM C1195 – 03 Standard Test Method for Absorption of Architectural Cast StoneSignificance and Use – This test method is to be used in determining the absorption of cast stone. Absorption is one measure of porosity of cast stone and, hence, its resistance to weathering and structural stress.This test method covers the sampling, preparation of specimens, and determination of the absorption of architectural cast stone.This test method describes two procedures: (1) cold water and (2) boiling water. The user of the test method should stipulate which is desired. If no stipulation is made, the cold water procedure will be used.
    3. ASTM C666 / C666M – 03(2008) Standard Test Method for Resistance of Concrete to Rapid Freezing and Thawing

      Significance and Use – As noted in the scope, the two procedures described in this test method are intended to determine the effects of variations in both properties and conditioning of concrete in the resistance to freezing and thawing cycles specified in the particular procedure. Specific applications include specified use in Specification C 494/C 494M, Test Method C 233, and ranking of coarse aggregates as to their effect on concrete freeze-thaw durability, especially where soundness of the aggregate is questionable.It is assumed that the procedures will have no significantly damaging effects on frost-resistant concrete which may be defined as (1) any concrete not critically saturated with water (that is, not sufficiently saturated to be damaged by freezing) and (2) concrete made with frost-resistant aggregates and having an adequate air-void system that has achieved appropriate maturity and thus will prevent critical saturation by water under common conditions.If as a result of performance tests as described in this test method concrete is found to be relatively unaffected, it can be assumed that it was either not critically saturated, or was made with “sound” aggregates, a proper air-void system, and allowed to mature properly.
  2. Cast Stone Institute Technical manual – Fourth EditionSignificance and Use – The Cast Stone Institute’s Technical Manual with Case Histories provides an introduction to the history of cast stone and its manufacturing disciplines and processes. The manual also provides a industry accepted specification as well as technical notes covering everything from anchoring to efflorescence to degrees of customization. There are of course detailed case studies with highly detailed plates shoeing successfully completed projects.
  3. Cast Stone Institute – Plant Certification program: Quality Control Procedures Required for Plant Certification

    Why choose a Cast Stone Institute Certified Plant?A CSI Plant Certification is your assurance that the manufacturing plant is continually subjected to the rigors of a proven, comprehensive, trusted and specified certification program. The inspection process is conducted by a third party engineer who addresses the following categories Safety, Personnel, the Manufacturing process, the Facility and with non negotiable results. Employees of the Company as well as Architects and Owners can rest assured that the Certified Plant is a Safe working environment that produces Consistent Quality Product.

  4. WR Grace DRY-BLOCK II certificationWhy WR Grace DRY-BLOCK II?An integral water repellent admixture specially designed to disperse throughout the mixture during manufacture of the cast stone units so that a uniform level of water repellency is achieved. Utilizing patented polymer technology, a long-term water repellency is developed.

    Corinthian Cast Stone is the ONLY WR grace DRY-BLOCK II Cast Stone CERTIFIED PLANT in the Country. Our products have been tested and Certified to have passed the stringent certification required by WR Grace.
