What is street creep?

Real Estate Agent with BHHS - Ambassador Real Estate

Have you ever been in a home and noticed a crack in the wall of the foundation in the garage?  This is typically caused by a phenomenon known as "street creep."  What is street creep?  Street creep is when the concrete expands and pushes on the driveway which subsequently pushes the floor of the garage against the wall of the garage which then causes causes the wall to crack. 

Are some homes more prone to street creep?  Yes, homes that are located on the bottom of a hill on a curve or homes at the bottom of a T intersection.  Why do these homes see street creep?  Concrete is just like anything else it flows downhill.  It is also important to remember that concrete expands and contracts with the weather and this also can effect the amount of street creep.

Can you prevent street creep?  Sometimes, if the home does not properly installed expansion joints in the driveway then street creep is more prone to happen.  This expansion joint is a gap that allows for movement of the concrete.  You can hire a professional contractor to cut the concrete with the proper depth.  Unless the expansion joint is the appropriate depth then the movement will still occur.

Sometimes, when selling a home you run across structural issues that are beyond the scope of a typical home inspection.  If you have a question in those situations you would want to consult a structural engineer.  A structural inspection typically costs approximately $200.  This is money well spent and a professional Realtor will strongly suggest this type of inspection if the situation warrants.

And this whole time I thought Street Creep meant some crazy guy on the street with stalker vision.

Honestly that is one of the most informative posts I've read here Dave.  I knew cement expanded and contracted and understood the usage of expansion joints but I never thought of the street affecting the houses but it makes sense.   I live 1/4 mile off the gravel road so I'm going to have to find another answer for the crack in my basement wall.

Is this type of crack mostly found in garage wall only and not floors? It would be interesting to see some pictures of this type of crack. Thanks for posting this information. I will have to look for it in locations of homes that you mentioned it is prone to be in.
