When are Foundation Cracks Normal or Signs of Foundation Problems?
Learn to answer the question – when are foundation cracks normal or when foundation cracking is a sign of foundation problems. Foundations often have cracks. Telling meaningful cracks from inconsequential cracks is important.
- Hi I’m Fred Marshall from Foundation Repair.
- I’m here to talk about foundation cracks and what they mean for you and your foundation.
- Foundations often have cracks.
- Telling meaningful cracks from inconsequential cracks is important.
- Even new concrete foundations have some cracks.
- The cracks are often caused by the hardening or curing process.
- As concrete cures, the concrete shrinks.
- Such cracks in newly formed slabs are called shrinkage cracks.
- Most shrinkage cracks are the inconsequential variety usually left are a 16th of an inch wide.
- Other cracks are caused by foundation movement.
- Foundations can bend but just a bit but not much.
- Excessive bending causes cracks.
- Cracks will often show up on the exterior and interior of a foundation.
- Cracks that are more than an 8th of an inch wide usually mean that the foundation has been bent.
- Because most foundations have steel in them, cracks will open and close but the two sides will stay at the same level.
- If the sides of the cracks are at different levels, like this, this suggests that, but does not guarantee that, there is a lack of reinforcing steel.
- When foundations are lifted, cracks do not always close.
- Cracks are often held open by pebbles or pieces of concrete.
- In other cases the sides may have shifted just enough to prevent the crack from lining up perfectly so it will not close.
- There is usually no need to fill cracks after a foundation has been lifted because most homes have a sheet of plastic under them often of a material such as Visqueen.
