See full version: Choosing an Installation System for Your Metal Composite Cladding
ALPOLIC ® has been an innovation leader in metal composite materials for decades and is the clear choice for architectural cladding because of its unsurpassed variety of colors, durability, and adaptability. However, our MCM products are just one part of the decision process when designing a building envelope. When it comes to selecting a cladding system, it is important to understand the options.
Rainscreen systems, do not rely on a single face-seal approach, but rather manage wind and water intrusion in a two-layer system. Most of the water intrusion is managed in the outer cladding layer, but an interior air water barrier (AWB) is required as a second line of defense. We’ll compare two common rainscreen systems that manage water intrusion differently.
Architects, fabricators and installers must select the system that meets their design and performance requirements. ALPOLIC ® frequently collaborates with these industry stakeholders to find solutions to unique challenges, such as designing an installation system capable of withstanding hurricane-force winds. A member of the Metal Construction Association (MCA), ALPOLIC ® is proud to be in the vanguard of industry, collaborating with a network of fabricators to ensure our products are integrated into a building envelope effectively. For additional reference, MCA released a Technical Bulletin defining basic installation systems in greater detail. [links]
Dry joints have been properly used in the past in which the bridge segments are formed by match casting. The prevalence in the past is due to it lower cost and time for construction. There is no gluing material to seal up the joint. As such, leakage through the joint into the box culvert occurs from time to time and this may affect the durability of external post-tensioning tendons. Moreover, owing to the effect of seismic, temperature and creep, the joints are found to open under these conditions. Spalling of top concrete slab at bridge joint was also reported.
Wet joint involves the use of epoxy glue at the mating precast segments. After the application of epoxy glue, a temporary precompression pressure of 0.3MPa is applied by stress bars at top, bottom and the sides of the mating precast segments. The epoxy sets under the applied pressure. The use of epoxy joints provides lubrication to help in the fit-up and alignment of the mating segments and minimizes the effect of hard point contact between segments.

In this method, fixed or embedded anchors, metal framing, steel brackets, or ties attach the stone to the surface. The method is applied only on thicker and stronger stone cladding, as the process requires drilling of a hole into the stone. This method demands a gap of ¾ inch to allow drainage. here
The natural stone cladding can be installed mainly by two methods, namely the wet installation method and dry installation method. Both the ways have their pros and cons, whose application is based on the objective and the wall conditions.
Dry stone mechanical method is the best and safest way compared to wet cladding installation. The process maintains a high level of accuracy while installing the stones. here
The spot bonding consumes less area of the tile to apply adhesive. It allows to have air pockets behind the stones. These air pockets avoid the chances of water standing, unlike the direct adhesion method. The method also lets the stone to have higher chances to stick on the wall, compared to the direct adhesion method.
Direct adhesion method is the most common wet met method employed. A wet method, by default, is considered a direct adhesion method. It makes use of a liquid latex combined with a cement-based filler powder to form cement mortar.
There are a number of different ways for the installation of natural stone few of them are listed below:
Natural stone such as granite, marble and limestone provide numerous design possibilities for the enhancement of front facades of spaces such as hotel lobbies, shopping mall, stores etc. natural stone is not only used for sprucing up the front façade but also used as flooring, pavement and interior cladding material.

Wet installation method which is also known as direct adhered method, is the most common method used for the installation of natural stone cladding. The reason behind its prevalence is its ease with which it can be used. [links]
