Learn how cracks in driveway could mean tunneling rats

Rats seek warmth and shelter as the weather turns colder and fresh food supplies as food supplies are exhausted outdoors. Rats can dig underground tunnels in an effort to find food and shelter. When their burrows extend under concrete, empty spaces are created in the slab’s soil foundation. These voids may not be visible, but they can cause a slab to sink, settle or crack.

To remain stable, concrete needs a solid foundation of supportive earth. These burrows cause the soil foundation to no longer have the integrity to fully shore up the slab. Eventually, the lack of proper support leads to sinking and settlement damage.
