#FoundationFactFriday: What are cracks for concern?

Foundation Fact: 66% of all foundations crack within the first year of being poured.

In previous installments of #FoundationFactFriday, we’ve learned about the weight of both a home and foundation including types of foundations and products to fix related settlment issues. Moreover, we’ve discussed the dirty details of expansive soils and its effect on foundations. CFS is dedicated to educating and assisting homeowners from the ground up. Now that we’ve learned the basic of foundations and soil types, let’s get to the causes of foundation issues.

Most homeowners assume there can be only one issue with a home’s foundation: a crack. A crack is only the beginning, as there are are many different types of cracks in many places and each crack should receive the appropriate repair. Turning a blind eye and failing to fix a crack can lead to some of the most costly expenses our homes can incur. A crack discovery can also end a pending home sale in a snap.

A cracked or settling foundation results from one of several common issues, and cracks can be located in several surfaces, such as bricks, mortar joints, walls, concrete slabs, doors, windows and even sloping floors. Concrete floors can also sink or crack over time. Cracks that result from a foundation’s settlement—a condition that strikes fear in the homeowner—can often be repaired at lower cost and with less inconvenience than most people imagine.

Cracks for concern: 

  • Stair Step or Diagnol Cracks – Among the most common of foundation cracks. These are often found in masonry in the mortar joints between bricks. These cracks point to a portion of the foundation that is settling unevenly, such as a corner that is sinking or settling in relation to the rest of the slab. If these cracks are 1/4 of an inch or larger consult an expert to assess the potential damage. 
  • Vertical Cracks – There are several different types of vertical cracks that can mean different issues for your foundation. Smaller, hairline vertical cracks often can happen after building a home due to initial settlement, but can worsen as time passes. While it always a good ideal to consult a professional to inspect any foundation cracks, these cracks are generally minor. Wide cracks, especially with varying widths at the top or bottom, point to serious issues that need to be seen to immediately. If the crack runs at a rough 45 degree angle or slant, discuss this symptom with an expert. 
  • Horizontal Cracks – Horizontal cracks along the foundation wall are often classified as the most seruous type of crack. These cracks indicate that the structural integrity of the wall has been compromised due to hydrostatic pressure from expansive soils. The strong force of the pressure can cause walls to bow or buckle, and is a leading cause of foundation cracks and water seeping in. 

General rule of thumb: If you can fit a dime in the crack, get it checked out.
