It is not cheap to pave your outdoor space, but it is typically worthwhile. So I understand if you step on a loose slab and become concerned because even the concept of replacing it could cost you a small fortune.

Why do patio slabs move?

Uneven slabs are dangerous to your family and friends, so make sure they are installed properly to avoid having a moving slab.
2. Soil movement
You’re probably surprised to learn that the soil beneath your slab can move. Moisture is the most common cause of soil movement.
There is usually movement in your slab as the under-slab moisture level increases or falls. It’s considerably worse when the moisture content rises or falls unevenly. When the soil has a high moisture content, it tends to expand, and when it has a low moisture content, it tends to shrink, causing movements of your slab.

3. Hefty weights
Most of our slabs are designed to withstand dead weight, and if your slab is not properly constructed, a constantly moving heavy object will cause it to move. The massive weights create soil movement, which causes the slab to slide when it is not correctly installed.
Consider selecting a slab design that can withstand big loads.

We have little control over nature, and we can’t stop it from becoming feral. Many things, including our patio slabs, are affected by the weather. Frost heave is a meteorological condition that contributes significantly to slab movement. Patio slabs will fracture or pull apart at the seams because the earth beneath your slab is frequently frozen and thawed.
