Any and all concrete cracks can pose a threat to the surrounding concrete as well as to your foundation given enough time. However, not every homeowner will have the time to treat every crack or sign of damage they might come across around their home. This is where knowing which cracks can be ignored for a short period of time and which cracks must be treated as soon as possible. Any cracks that measure less than 1/8 inch wide are known as hairline cracks and will not pose any immediate threat to the surrounding concrete, nor will they spread down to the foundation right away. The same can be said for any cracks that measure anywhere between 1/8 and 1/4 inches wide.
Of course, these cracks can also expand at any time, so it is important that you do not leave these cracks alone for too long. Any cracks that measure wider than 1/4 inch must be repaired as soon as possible. Not only can they spread damage out to the surrounding slabs, but they can easily creep down to the foundation, too. You need a concrete lifting solution that will prevent this damage from spreading as well as protect your concrete from being damaged again in the future.
