Cracks that are wider at one end. Cracks that get bigger over time. Step cracks in masonry joints are a major concern, especially if the wall is bulging or the crack is wider than ¼ inch. A clogged gutter or other humidity problem on the outside is probably putting pressure on that part of the wall.
Horizontal cracks in your basement foundation are serious. This type of crack is often due to unbalanced soil and the hydrostatic pressure of water pressing against the foundation wall. You may notice that the foundation slopes inward and water leaks into the basement. Both block foundations and pours can develop horizontal cracks.
Foundations exposed to an earthquake, subsidence pit, or landslide pressures or slope creep often If you discover this type of foundation damage, it is important that you repair it as soon as possible before the structural integrity of your home is compromised. Garages often have control joints to provide weak spots where concrete can crack without affecting aesthetics, strength or safety. When leaks occur in pipes, either from water lines or sewer pipes and moisture migrates around or under a base, cracks can occur. Cracks in concrete foundations can be good or bad depending on the extent of the damage they cause and the structural problems they pose to your Denver home.
If the cracks are wide and there is a lump on the foundation wall, there could be hydrostatic pressure on the wall, this is definitely a cause for concern. Most houses with brick cladding have triangular cracks on both sides of at least one corner of the foundation wall; occasionally, the concrete corner comes off. I didn't realize there was so much you could learn from the different types of foundation cracks, especially the diagonal cracks and the inward slope of the interior walls. If these are the questions that are spinning in your head, read on and find out the types of foundation cracks and when you should be concerned as a homeowner.
Cracks larger than a quarter of an inch may be nothing, but they can also be, especially if the wall on one side of the crack protrudes more than the other. If the crack continues to enlarge or the wall is out of lead, review by a structural engineer is recommended. Sometimes a buyer or homeowner wants a second opinion or more information about their foundations or cracks, but isn't sure who to consult. Poor drainage near the foundation of a house is actually one of the most common causes of cracks and foundation damage.
However, because basement and garage slabs are supported by the ground, ¼ inch wide or larger cracks, vertical displacement in a crack line (the slab on one side of the crack line is higher than the other) or slab slump can be a sign of a fault in the ground below and is recommends a review.
