Expansive soils and differential settlement are common in our area.  Expansive soils are the leading cause for differential movement in foundations in our area as well.  If you enjoy YouTube and technical construction issues you should consider subscribing to Practical Engineering.  I recommend subscribing to their feed and hitting that like button.  Practical Engineering does a great job of explaining expansive soils and their effects on your foundation’s performance.  No need to reinvent the wheel, or in this case the video, so I wanted to share Practical Engineering’s video on this subject for you here and I hope you enjoy it.  Do some further reading on our website and you can find foundation maintenance recommendations that you can implement to reduce the effects of expansive soils on the performance of your foundation.  If you have concerns about the performance of your foundation, contact our office and schedule an appointment to have an engineer evaluate the foundation of your building.
