Protecting Your Concrete from Colorado's Harsh Winter

Protecting Your Concrete from Colorado

Colorado winters test everything—including your concrete. The combination of freeze-thaw cycles, deicing salt, and snow removal can cause significant damage if you’re not prepared. Here’s how to protect your concrete investments with proper maintenance and concrete sealing.

Understanding Winter Damage

The Freeze-Thaw Cycle

From what we see in the field, Colorado Springs is unique because we don’t just freeze once and stay frozen; we oscillate. Our region can experience over 40 freeze-thaw cycles in a single winter season.

The process:

1. Water enters concrete through pores and cracks
2. Temperature drops below freezing
3. Water expands as it freezes (by about 9%)
4. Expansion creates internal pressure
5. Temperature rises, ice melts
6. Process repeats

The damage:

• Surface spalling (flaking/peeling)
• Scaling (top layer deteriorating)
• Cracking from internal pressure
• Accelerated settling

Salt Damage

Deicing salt helps with safety but harms concrete.

How salt damages:

• Increases freeze-thaw cycles (salt melts ice, water refreezes when salt dilutes)
• Creates more intense freeze damage
• Chemically attacks concrete surface
• Draws moisture into concrete

Common salt damage:

• Pitting and rough surfaces
• White staining and deposits
• Accelerated spalling
• Rebar corrosion (in reinforced concrete)

Snow Load and Removal

Heavy snow and its removal create issues.

• Weight can accelerate settling in weakened areas
• Plowing and shoveling scrape surfaces
• Metal blades chip edges
• Piled snow concentrates water during melt

Pre-Winter Preparation

Assess Current Condition

Before winter hits, evaluate your concrete.

Look for:

• Existing cracks (water entry points)
• Spalling or flaking areas
• Settlement or uneven sections
• Failed caulking at joints

Act on:

• Cracks need sealing before freeze
• Spalling areas may need attention
• Settlement should be corrected before winter
• Caulk should be replaced

Consider Leveling Now

If you have settled concrete, fall is ideal for leveling.

Why pre-winter leveling helps:

• Eliminates water-collecting low spots
• Restores proper drainage
• Voids beneath slabs get filled
• Concrete enters winter properly supported

Winter leveling considerations:

• We can work in temperatures above 35°F
• Winter scheduling may be limited
• Spring becomes the alternative

Seal Critical Joints

Caulking is essential winter prep.

Priority areas:

• Driveway-to-garage joint
• Expansion joints in driveways
• Patio-to-house transition
• Any visible gaps or separations

Why it matters: Water entering joints before freeze causes maximum damage—both to the concrete and the soil beneath.

Apply Concrete Sealer

Sealing reduces water absorption and salt damage.

Sealer benefits:

• Blocks water from entering pores
• Reduces salt penetration
• Protects against chemical damage
• Makes spring cleaning easier

Timing: Apply sealer at least 30 days before first freeze for proper cure.

During Winter: Best Practices

Safe Deicing

If you must use deicers, choose carefully.

Better choices:

• Calcium chloride (less damaging than rock salt)
• Magnesium chloride (gentler on concrete)
• Sand or kitty litter (traction without chemicals)
• Avoid if concrete is less than 1 year old

Avoid:

• Rock salt (sodium chloride) on new concrete
• Ammonium sulfate or ammonium nitrate (very damaging)
• Excessive amounts of any deicer

Application tips:

• Use sparingly—more isn’t better
• Spread evenly
• Remove slush before it refreezes
• Rinse concrete in spring

Smart Snow Removal

Protect concrete while clearing snow.

Best practices:

• Use plastic shovels or snow blowers when possible
• If using metal blade, keep it slightly raised
• Clear snow before it compacts into ice
• Avoid letting piled snow melt against concrete

Avoid:

• Metal blades scraping the surface
• Chipping ice with sharp tools
• Piling snow against foundation
• Using hot water to melt ice (thermal shock)

Monitor Problem Areas

Watch for developing issues.

Check regularly:

• Joints opening up
• New cracks appearing
• Spalling or flaking
• Standing water during thaws

Document what you find for spring assessment.

Special Winter Situations

Heated Driveways

If you have heated concrete, it changes the game.

Pros:

• No deicing chemicals needed
• No shoveling
• Reduced freeze-thaw at surface

Considerations:

• Maintain proper heating schedule
• Rapid temperature changes still stress concrete
• Doesn’t prevent all settling
• Requires maintenance of heating system

Concrete Less Than 1 Year Old

New concrete is especially vulnerable.

Extra precautions:

• Avoid all chemical deicers first winter
• Use sand only for traction
• Be extra careful with snow removal
• Consider applying sealer before winter

Stamped or Decorative Concrete

Decorative surfaces need special care.

Concerns:

• Sealers can wear in high-traffic areas
• Texture traps water and salt
• Damage is more visible
• Repair is more complex

Care tips:

• Maintain sealer regularly
• Use only approved deicers
• Clean gently in spring
• Consider professional maintenance

Spring Recovery

When winter ends, recovery begins.

Thorough Cleaning

As soon as weather permits, clean the surface.

• Power wash to remove salt residue
• Clean debris from joints
• Remove sand or grit buildup
• Allow to dry completely

Assess Damage

Look for winter’s toll.

• New cracks or widened old ones
• Spalling or scaling
• Joint material failure
• New settling

Address Issues Promptly

Spring is ideal for repairs.

Prioritize:

1. Safety hazards (trip hazards, severe damage)
2. Water management issues (drainage problems)
3. Cosmetic damage
4. Preventive maintenance

Plan for Next Year

Based on what you learned, plan ahead.

• Was sealer adequate?
• Did caulking hold up?
• Are there areas needing leveling?
• Should you change deicing practices?

The Prevention Investment

Compare the cost of prevention vs. repair.

Prevention	Cost	Protects Against
Sealing	$0.50-1.50/sq ft	Surface damage, salt
Caulking	$3-5/linear ft	Water infiltration
Leveling	$3-8/sq ft	Void-related damage

Repair	Cost
Spalling repair	$3-8/sq ft
Crack repair	$150 minimum
Replacement	$12-20/sq ft

Prevention costs a fraction of repair.
