RockCast Custom Cast Stone Installation Guidelines

For Commercial Contractors & Designers


General Installation Requirements

RockCast Custom Cast Stone products must be installed in accordance with standard masonry specifications and within the guidelines of local building codes.

Always refer to relevant NCMA TEK Bulletins and RockCast product specifications (varies by series) when installing architectural stone units in conjunction with masonry.


Blending and Color Variation

  • RockCast products are made from natural limestone, which inherently features a range of color tones as part of its visual appeal.

Cutting and Finishing

  • Use motor-driven masonry saws to cut units.
  • Place the finished end facing outward, and rotate saw cuts inward to conceal exposed aggregates and saw marks within mortar joints.

Mortar and Joint Guidelines

  • Set units in a full bed of mortar, unless specified otherwise in project drawings.
  • Vertical joints must be filled with mortar.
  • Maintain 3/8” joints, unless other dimensions are indicated in the plans.
  • Use Type N mortar where applicable (per ASTM C270).

Anchoring and Dowel Holes

Where specified, fill all dowel holes and anchor slots completely with mortar or non-shrink grout to ensure secure placement.


Sealing Requirements

Sealing is not required, as RockCast units are manufactured with an integral water repellent (IWR).


If sealing is necessary, use a non-bridging breathable sealer such as:

  • Prosoco Sure Klean® Weather Seal (Siloxane WB Concentrate or Siloxane PD)
  • Hydrozo® Enviroseal 7

Apply sealers per manufacturer’s recommendations.


Protection During and After Installation

  • Cover wainscot with plastic, felt paper, or another approved barrier for protection.
  • During the curing process—especially in wet or cold conditions—cover freshly installed masonry with plastic to keep the wall system dry and ensure proper curing.

Moisture Control, Shrinkage & Cracking

Best Practices for RockCast Architectural Stone Products



Understanding Shrinkage in Concrete Masonry

RockCast architectural stone products, like all concrete masonry, may undergo slight shrinkage over time. The most common causes include:

  • Drying shrinkage
  • Temperature fluctuations
  • Carbonation
  • Differential movement

These factors must be considered during design and installation to prevent cracking and ensure long-term performance.


Differential Movement with Clay Brick

Kiln-fired clay brick expands as it absorbs moisture, while concrete masonry units like RockCast shrink slightly.

When using RockCast in combination with clay brick, this differential movement must be managed.

  • Consult your selected brick manufacturer for specific expansion data.
  • Be aware that some clay brick continues to expand over several years due to weather conditions.
  • Not all brick expands at the same rate, so follow manufacturer-specific guidance.

Mortar Considerations

  • Use of an IWR (Integral Water Repellent) mortar additive is recommended but not required, unless the design specifies a water-repellent wall system.
  • This additive helps enhance the moisture resistance of the overall system.

Control Joints and Crack Management

To control movement and minimize cracking.


Install control (elastic) joints at strategic locations:

  • At openings (windows, doors, etc.)
  • Where wall height changes
  • At wall intersections and corners
  • On long uninterrupted walls (spacing no greater than 1½ times the height of the masonry)

Important: This spacing recommendation applies only to the masonry portion. If clay brick is used in conjunction, treat it separately and follow appropriate brick expansion guidelines.


Recommended Resources

Refer to the following NCMA TEK Bulletins for proper crack control and design:

  • 10-1A: Design of Concrete Masonry for Crack Control
  • 10-2D: Control Joints for Concrete Masonry Walls — Empirical Method
  • 10-4: Crack Control for Concrete Brick and Other Concrete Masonry Veneers
  • 5-2A: Clay and Concrete Masonry Banding Details
  • 3-6C: Concrete Masonry Veneers (for anchoring guidance)

Note: References in TEK bulletins to horizontal joint reinforcement do not apply to RockCast Architectural Veneer units and are not required, unless the designer elects to reduce or eliminate control joints.
