- Technical Information
Managing Moisture Control, Shrinkage and Cracking
Reading Rock’s Caliza Stone, like all concrete masonry products, may shrink slightly. The most common shrinkage/resistant issues come from drying shrinkage, temperature changes, carbonation and differential movement.
- Kiln fired clay brick expands as it absorbs moisture and concrete masonry units shrink. This differential movement needs to be controlled when utilized with clay products.
- In using elastic (control) joints, refer to NCMA TEK Bulletins 10-1A Design of Concrete Masonry for Crack Control, 10-2B Control Joints for Concrete Masonry Walls — Empirical Method, 10-4 Crack Control for Concrete Brick and Other Concrete Masonry Veneers, and 5-2A Clay and Concrete Masonry Banding Details for guidelines. Refer to NCMA TEK Bulletin 3-6B Concrete Masonry Veneers for proper veneer anchoring.
- Control joints are required at all openings, changes in wall height, between main intersecting walls, corners and for long running walls without openings at a distance of 1 1/2 times the height of the masonry, as outlined in TEK Guide 10-2B. The empirical method notes that the distance is for the masonry only and if brick is used, it is should be treated independently for “expansion” and the appropriate brick technical guidelines followed. The most common shrinkage/ restraint issues come from drying shrinkage, temperature changes, carbonation and differential movement.
- Cavity wall construction is recommended with proper flashing, venting and weep holes.
- Install weep holes and vents at proper intervals and at any water stops over windows, doors and beams.
- Typical brick wall ties can be used depending on the backup structure. When seismic conditions occur, consult your local building codes for proper sizing and placement.
- All window sill and coping unit head joints should be raked and caulked with a matching color. Flashing should always be used in these locations.
Do’s and Don’ts
Best Practices for Working with Caliza Stone, The Next Generation
Viewing conditions should be equal to the approved field panel when viewed in direct daylight and similar weathering conditions.
- Cut units should be done neatly with an abrasive or diamond blade mortar-driven masonry saw and placed strategically for the best appearance. Cut ends should not be exposed.
- Protect Caliza Stone units at all times to prevent chipping, cracking, staining, or other damage.
- Handle long units at the center and both ends simultaneously to prevent cracking.
- Store units on pallets with nonstaining waterproof covers.
- Do not double stack pallets.
- Install units from multiple cubes.
- Do not use pry bars or other equipment in a manner that could damage units.
For installation tolerances comply accordingly:
- Variation from Plumb: Do not exceed 1/8″ in 5’or 1/4″ in 20′ or more.
- Variation from Level: Do not exceed 1/8″ in 5′, 1/4″ in 20′, or 3/8″ maximum.
- Variation in Joint Width: Do not vary joint thickness more than 1/8″ or 1/4″ of nominal joint width, whichever is greater.
- Variation in Plane between Adjacent Surfaces: Do not exceed 1/8″ difference between planes of adjacent units or adjacent surfaces indicated to be flush with units.
- Protect your work by covering the walls at the end of each day during the installation process. Upon completion, make sure to cover all finished surfaces to protect wall from other installations that could damage (stain) the units. During installation, it is recommended that all corners be covered with plywood to protect them from any damage.
- Clean Caliza Stone by wetting down the surface before using appropriate masonry cleaners such as Prosoco, Custom Masonry Block Cleaner, Vanatrol or EacoChem’s NMD80, following the manufacturer’s directions and rinse thoroughly. Power washing, sandblasting and the use of muratic acid are not recommended procedures for cleaning Caliza Stone. Cleaning should be complete on final wall installation within 14-21 days of installation.
- Patching of small chips can be done like repairing other CMU products and stone. Large imperfections should be replaced. A matching colored patch kit is available. Contact Reading Rock for more information.
