Water Repellents: Care And Maintenance – Technical Bulletin #35
The technology of waterproofing masonry materials has improved considerably in the last few years and many durable water repellent materials are available which can reduce water intrusion through brick, stone and mortar joints. Proper application of waterproofing materials can be a long lasting minimizer of efflorescence, mildew, staining and dirt. Many materials are offered with…
Degrees Of Customization: Design Tips – Technical Bulletin #45
Improvements in the availability and economy of Cast Stone can often be achieved when the Specifier balances the needs of a project with the degree of custom shapes needed for the cast stone installation. The indirect labor costs of design, layout, supervision, coordination and mould making needed for a “full custom” project can greatly exceed…
Seismic Considerations: Design Tips – Technical Bulletin #34
Seismic and wind load are the principal live loads which are considered in designing masonry walls. Seismic loads may be a major, minor or inconsiderable factor in wall design, depending on the geographical location of the structure. Seismic zones, ranging in severity of effects to be considered, from a low of 0 to a high…
Use Of Reinforcement For Cast Stone: Design Tips – Technical Bulletin #51
One of the advantages of Cast Stone over natural stone is its ability to contain integral reinforcement for added strength. This gives the material a distinct advantage by combining the high compressive strength of the stone materials with the tensile strength of billet steel reinforcing bars, to provide safety and control of cracking. The preferred…
Patching: Care And Maintenance – Technical Bulletin #38
The best insurance against chipped stone is care in handling and protection of the unit after installation. Even with all of the special care and protection, building stone still becomes chipped from time to time and a certain amount of patching is to be expected. Any chip obvious from a 20′ distance should be patched.…
Maximum Length Considerations For Cast Stone: Design Tips – Technical Bulletin #53
Designers specifying Cast Stone often require guidance on the limitations of the possible sizes of Cast Stone elements. This Technical Bulletin addresses the many factors that must be considered in determining Cast Stone sizes including structural and physical properties of the material, manufacturing limitations, weight, transportation and handling, cost, and dimensional tolerances. By examining these factors, the…
Job Site Handling And Installation: Design Tips – Technical Bulletin #37
The on-site personnel should be familiar with the applicable sections of the Cast Stone Institute Specifications and the Project Specification pertaining to delivery, storage, setting, patching, cleaning, pointing, caulking and sealing. In case of a conflict between the two specifications, the Project Specification should prevail. Where the Project Specification may not include a particular issue,…
Inspection And Acceptance: Design Tips – Technical Bulletin #36
On site inspection and acceptance of Cast Stone should be performed at time of delivery and again after all material has been installed, pointed and cleaned. Final Inspection should be done prior to application of water repellents. The on site inspector should be familiar with the project specification as well as the applicable referenced standards.…
Hot Weather Setting Practices: Design Tips – Technical Bulletin #48
Special precautions must be taken when setting Cast Stone in hot weather. The stone setter must take measures to ensure that the quality of the installation does not suffer from high temperatures. Hot weather is defined to be temperatures above 90 degrees F (32 degrees C). The primary concern, to the masonry contractor during hot…
Freeze / Thaw Durability: Design Tips – Technical Bulletin #40
Architectural cast stone is a product which has been used for many decades in all types of climatic conditions. In order to reasonably assure the user that the cast stone being supplied by a particular producer is durable in freeze / thaw conditions, the cast stone manufacturer has two options. The first, and most common…
