- In Foundation Crack Repair
Your home is your number one most valuable investment – so it makes sense that maintaining your home’s structural integrity is a high priority. When the structural integrity of a house has been compromised, a variety of unpleasant problems can occur. But how can you tell the difference between normal wear and a problem that needs immediate attention?
Your home’s foundation is, well, the foundation of your home’s overall structural integrity. Foundations are generally constructed of concrete poured over steel; as time passes and the elements take their toll on the home, all concrete will crack to some degree. (As we like to say, concrete is made to do two things: harden and crack.) The steel reinforcement is in place to hold the foundation together when it cracks – and this is expected, to some extent.
What is Settling?
Settling is a term used to describe the natural changes that will take place in a foundation due to time and weather. Over time, a new home will very gradually sink down further into the ground. Contractors take the climate and soil into account when overseeing a home’s construction, and they know to expect a bit of settling as time passes.
Even brand-new homes are in grave danger; some of the worst damage our experts at Family Waterproofing Solutions have seen has been on homes less than 5 years old. Damage can be caused by improper soil preparation when the home is built, or by extreme weather conditions. For example: a home is built in the middle of a rainy fall season after a relatively wet summer; the expansive clay soil is as swollen as it can get. Over the next 3 years, the house experiences normal settlement; but when an extreme drought hits in year 4, the clay retracts and the house plummets 5 inches in the space of just a few months.
The biggest contributor to settling is soil expansion and contraction. As the soil loses or gains moisture and is exposed to the elements, it shifts beneath the weight of the structure. Soil expansion affects the foundations of about one-quarter of all American homes, according to the American Society of Civil Engineers. Even though a bit of soil expansion is to be expected, this naturally occurring settlement of the foundation can lead to problems.
How to Distinguish Foundation Problems from Settling
In order to diagnose a true foundation problem, you’ll need to look for more warning signs than just visible cracks in your foundation. Visible cracks in the foundation can be a first sign of a problem, but they can also be a sign of non-threatening settlement. A real foundation problem will have a combination of other signs, some of which we’ve listed below.
Old houses might be charming, but advanced foundation problems definitely are not.
Cracks in Walls:
This is one of the primary indicators that your foundation has been compromised. A jagged crack running off at a forty-five degree angle is a sure sign that your foundation is seriously shifting and has resulted in actually tearing the sheetrock apart.
Sticking Doors or Windows:
Inspect all of your doors and windows. If you have doors or windows that consistently stick for no apparent reason, these can be a sign of your foundation shifting. This happens because the door or window frame twists out of balance as the foundation moves.
You might assume that any foundation issues would be most obvious near the ground – but the opposite is actually true. When a foundation has been compromised, the most obvious signs of damage will be near the top of your house rather than the bottom. Carefully inspect the top story of your home from the outside using a ladder. Look for cracks that appear above window frames – this is the most common place for damage to become visible. If you have a brick home, look for a stair-stepping crack in the veneer of the brick.
Of course damage can be visible within the foundation itself as well. Look for horizontal cracks in the actual foundation. A horizontal crack is a sign of hydrostatic pressure, or too much water pressure building up behind the foundation
