Natural stone surfaces such as granite often seem like they would be indestructible but it isn’t so. While they are one of the hardest substances known to man, they and do crack from shifting weight, heat, and sudden impact like when something is dropped on it from above. It also has some cracks that were there since the rock was formed.
They start out as tiny little fissures that can separate over time due to wear and tear on the surface. Here are a few reasons this happens:
Cracking and Breaking in Nature
Workers and masons cut and remove the stone from big rock quarries to be made into building materials such as stone slabs and pillars. They will first look for natural cracks in the stone to decide how it will need to be cut. Sometimes a fissure is easier to cut along because it is larger and wider, allowing for a natural separation. Once the rock has been cut and removed they will have to be cut in the factories a certain way to cover up the edges. Stone is very difficult to cut.
A fissure is larger than a crack and is a natural feature of the rock. What is the difference between a crack and a fissure? Fissures are a natural occurrence during the time the rock was being formed. It is a part of the natural beauty of the stone itself. You could say that it is like a split in the layers of the rock, sometimes revealing a layer underneath. A crack, on the other hand, is thin but expands over time and may cause structural issues and instability. They begin as tiny hairline cracks that may eventually break off.
These cracks can be repaired if attention is given to it right away. Depending on the severity of the crack, it may need to be fixed by a professional stone restoration specialist. If it is a small crack you may be able to fix just that one section without having to replace the whole piece. Like smoothing the edge with a bevel.
Should you decide to take on a project like this yourself, you should be aware that it is not an easy task. You should do some research on it before you decide to attempt it.
There are many resources available online to show you how to do it. But be sure to find a guide for stone restoration before you begin. There is no shortage of how-to information on the Internet to guide you through the process. YouTube and Vimeo are two channels where you can find how-to videos.
While it is possible to do these types of repairs yourself, it is often easier and more cost-effective to find a stone restoration specialist to assess the situation and come up with a plan of action to repair the material quickly and without causing any further damage.
