The Freeze Thaw Cycle Explained: Why Central Washington Winters Are Tough on Concrete

Understanding the Problem

Central Washington’s weather can swing dramatically between freezing nights and sunny afternoons. While that’s part of what makes the region beautiful, it also creates one of the biggest challenges for concrete surfaces such as driveways, sidewalks, patios, and pool decks.These temperature changes trigger the freeze thaw cycle, a natural process that can cause concrete to crack, shift, and deteriorate over time.

What Is the Freeze Thaw Cycle

The freeze thaw cycle occurs when water seeps into small cracks or pores in your concrete. When temperatures drop, that water freezes and expands, putting pressure on the concrete from within. When it thaws during the day, the water contracts and leaves behind tiny gaps. Over time, these cycles widen cracks, weaken surfaces, and can cause entire slabs to lift or sink.

During a single Central Washington winter, this process can repeat dozens of times, creating significant damage before spring arrives.

Signs of Freeze Thaw Damage

You may already notice the warning signs of concrete freeze thaw damage on your property. Common indicators include: 

• Cracks forming or widening in driveways or walkways 

• Sunken or uneven concrete slabs 

• Pitting, flaking, or crumbling surfaces 

• Pooling water near concrete slabs 

• Gaps forming between joints or seams

Ignoring these early signs can lead to much more costly repairs later, especially if moisture continues to seep beneath the surface.

Why Central Washington Conditions Make It Worse

Central Washington’s dry climate and sharp temperature swings make the freeze thaw cycle especially tough on concrete. Concrete in Yakima, Ellensburg, and the Tri Cities often experiences freezing nights followed by daytime thaws, the perfect environment for expanding cracks and structural damage.

Sandy or loosely compacted soil beneath concrete can worsen the problem, creating voids that cause slabs to settle or become uneven.

How Level Best Northwest Can Help
