Technical Data

Architectural specifications, material properties, installation guides, cleaning and dampproofing, and reference material for genuine Indiana Limestone.

Architectural Specifications

Indiana Limestone masonry is specified under these CSI MasterFormat sections:

  • Division 04 Masonry, Section 044308 — Limestone Masonry
  • Division 04 Masonry Veneer, Section 044311 — Limestone Masonry Veneer, and 044313–18 — Adhered Limestone Masonry Veneer
  • Division 32 Exterior Improvements, Section 321440.11 — Limestone Paving

Material Properties

  • Weight: approximately 144 lb/ft³
  • Compressive strength: 4,000 PSI minimum (ASTM C170)
  • Moisture absorption: minimum 7.5% rated; production values run closer to 4%, classifying it medium density
  • Grades: select, standard, rustic and old gothic — structurally essentially identical
  • Reserves: estimated at 500–600 years at current extraction methods

Installation & Technical Guides

Per-product installation diagrams and technical information exist for the three Building Veneers finishes, and guides exist for each Trim & Accent and Landscape Stone product:

Installation Detail Drawings document veneer product applied over wood stud, metal stud, or concrete block wall construction, with details for foundation, parapet, floor line and shelf angle, expansion joint, window and door, limestone-to-other-material transition, corner condition, and corbeling/racking conditions.

Cleaning, Dampproofing & Sealing

  • Pressure clean at no more than 1,200 psi, nozzle held at least 1' away, fan tip approximately 12" wide
  • Dampproof unexposed areas at grade up to 12" and totally below grade
  • Sealing is not recommended due to staining potential — consult your engineer
  • Anchors should be stainless steel or otherwise non-corrosive

Reference

The Indiana Limestone Institute publishes a handbook and technical notes on the following topics, listed here for reference. No PDF copies of these documents are hosted on this site:

  • Anchors and Support
  • Cleaning Indiana Limestone
  • Damage and Repair Practices
  • Durability and Weathering
  • Grouted Cavity Walls
  • Hand Rails and Posts
  • Joint Sealants
  • Panel Sizes
  • Recommended Wall Heights
  • Safety Factors
  • The Use and Overuse of Testing in Specifying Dimension Limestone
  • Wood and Steel Stud Construction
  • Water Repellents

Indiana limestone is eligible for Solar Reflectance Index (SRI) credit toward LEED 2009 and LEED v4 for non-roof applications.

A full test report referenced in the archived technical material states no silica was found in any grade or color of Indiana limestone from either quarry referenced there. This is restated here only as a recovered claim about the material — not a safety assurance from Limestone Classics — and no report is linked because none is hosted here.
