Granite is one of the most popular materials used for countertops due to its fascinating natural beauty and aesthetics. Granite countertops are strong, durable, and attractive, but like other materials, they can crack. There are a few common causes of granite countertop cracks that should be considered when selecting a granite countertop.
One of the most common causes of granite countertop cracks is poor installation. Granite is an incredibly heavy material and requires proper support to be properly installed. A professional installer should ensure the correct support is provided to hold weight like a heavier cooktop or a sink. Improperly securing granite countertops can cause cracking.
Another common cause of granite countertop cracks is accidental impact damage. Granite is a strong material but can still suffer damage when it is impacted hard enough. Repeatedly setting hot cookware on the counter can result in cracks due to thermal cycling. Dropping heavy items onto the countertop may also lead to cracks.
Improper care for granite countertops can also lead to cracks. Granite countertops should be kept clean and dry, and spills should be wiped up right away. Cleaning with harsh chemicals should also be avoided, as it can erode away at the sealant and cause granite countertop cracking.
Dynamic loads are due to sustained weight, and can also cause problems with granite countertops. For example, granite countertops around kitchen sinks can suffer cracking due to years of water running along its edge during sink use.
Temporary or seasonal shifts in temperature can also lead to granite countertop cracks. Granite is a naturally occurring material and its molecular composition is inclined to expand and contract with temperature fluctuations. Years of repeated thermal cycling can result in fatigue and eventual cracking of granite countertops.
Uneven subsurface preparation before the granite countertop is installed can also lead to cracking. A flat and even subsurface void of any craters or unevenness is essential for providing adequate support for the weight of the granite countertop.
The type of granite used can also play a role in granite countertop cracking. Granite with more of a soft grain is less likely to withstand the loads like a honed finished granite or a rougher texture with larger grains.
Finally, in rare incidents natural fissures present in the granite prior to fabrication can lead to cracks. Granite slabs are hand selected and inspected prior to fabrication but it is possible that a small fissure may go undetected.
If you are considering granite countertops for your home, it is important to be aware of the common causes of granite countertop cracks. While most granite countertop cracks can be attributed to poor installation or impacts, it is also important to know the other causes of granite countertop cracks to be sure you select the best granite countertops for your needs. By understanding these common culprits, you will be more knowledgeable and prepared when selecting your next granite countertop.
