Causes and Consequences:
Understanding Street Creep
Street creep, also known as “driveway creep,” happens when expanding concrete during hot weather exerts excess pressure on your driveway and foundation.
Concrete is susceptible to thermal contraction and expansion, growing slightly in summer and shrinking in winter. To mitigate this, contractors create small gaps between concrete slabs called expansion joints, which help prevent cracking.
However, over time, expansion joints can lose their effectiveness. In winter, as slabs contract, these joints may widen and become clogged with sand, rocks, and dirt, compromising the buffer space between the slabs.
When temperatures rise and the slabs expand, they push against neighboring slabs, creating a chain reaction that can extend up to your garage and, ultimately, your home.
To effectively prevent street creep, it’s essential to understand its causes and the potential damage it can inflict.
