Masonry work can add a lot of character to a home. If the masonry work is exposed to the elements, however, it can get damaged over time. As with a lot of damaging conditions, water is usually involved. As masonry work ages, it will crack, and these cracks will let water enter, which then will cause the crack to expand even wider. In time, your once beautiful masonry work will be crumbling apart.
What can you do to prevent this from happening? Your first step is preventing water from entering the cracks in the first place. There are different types of sealant available that will last for quite a while, but it is important to keep up with it, since the sealant will wear off over time.
You should also make sure that the ground is properly graded to drain water away from your masonry work, so that water isn’t pooling around it.
