Foundation Cracks in Hermitage TN
Do you have a crack in your foundation wall? Before you reach for that crack sealer, it’s important to learn a thing or two about foundation cracks. One of the most important things you should note is that these cracks are often a sign of a much deeper problem.
Proper diagnosis of the underlying cause of the cracks is necessary if you don’t want to waste your hard earned money on ineffective or inefficient repair. There are several factors to be considered in order to determine the best repair method. These include:
- Location, location, location
Location isn’t just important for selling real estate. It is also one of the most important factors to consider when you encounter foundation cracks. Cracks in foundation walls are often an indication of the wall’s movement against external pressure from the surrounding soil. Cracks in foundation floors are often indicate a sinking foundation.
Because the locations of the cracks indicate different problems, the methods for repair of these cracks will differ.
- The shape of the crack
The shape of the crack also indicates the underlying cause of the cracking. Cracks that are wider at the top and begin to taper off towards the bottom are usually a sign of structural failure. Diagonal cracks are often a result of settling or lateral pressure against the wall from expanding clays soils. Horizontal cracks are often caused by earth loading against the foundation wall.
If the underlying cause of the cracks is not solved, the cracks will continue to grow and may cause and even worse problem.
- Size of the cracks
The method and intensity of repair is often determined by the size of the cracks. Small hairline cracks can be easily sealed to prevent seepage. Cosmetic repairs can be applied to most cracks that are less than a quarter inch.
Larger cracks require more intensive repairs that may include the installation of carbon fiber strips or even straightening the wall.
- Conditions of the site
Foundation repair experts will also look at the conditions of the site. This includes looking into the repair history of the foundation. This will help to determine the best method for repair. For example, the drainage system of your neighbor’s property may be affecting your foundation and causing problems. Repairs would be useless until this drainage problem is addressed.
- The rate of change of the cracks
Are the cracks still growing? Have they changed in the past few days? Changes may indicate continued movement. A non-changing crack may be an indication of a one-time event.
