Cracked concrete is more than just a cosmetic concern it’s often a sign of deeper structural or environmental issues. Whether on your foundation walls, basement floor, driveway, or sidewalk, these cracks can lead to water infiltration, mold growth, erosion, and compromised structural integrity. At Residential ResQ, we specialize in concrete crack sealing, a vital process that protects your home from costly damage and extends the lifespan of your concrete surfaces.
Understanding Why Concrete Cracks
Concrete is strong but not invincible. It’s prone to cracking for several reasons, some of which are avoidable and others that result from natural processes:
1. Shrinkage During Curing
Concrete shrinks as it cures. If not properly managed, this shrinkage can cause small surface cracks known as shrinkage cracks.
2. Soil Movement
Changes in the soil beneath concrete due to freezing and thawing, drought, or heavy rain can cause uneven settlement, leading to cracking.
3. Overloading
Driveways, patios, and garage floors bear weight. If this load exceeds what the concrete was designed to support, cracks can appear.
4. Temperature Fluctuations
Extreme temperatures cause concrete to expand and contract. Without the proper expansion joints, these movements lead to stress fractures.
5. Poor Installation Practices
Improper mixing, inadequate curing, or lack of control joints can result in premature cracking and compromised strength.
Why Concrete Crack Sealing Is Essential
Ignoring even the smallest crack can have serious consequences. Here’s why concrete crack sealing is a must for homeowners:
Prevents Water Infiltration
Cracks allow water to seep into the concrete and below it. This is particularly dangerous in basements and foundations, where water intrusion can lead to mold, mildew, and structural damage.
Stops Crack Growth
Sealing prevents existing cracks from widening and new ones from forming. This protects your concrete from further stress and degradation.
Avoids Costly Repairs
The earlier you address cracks, the easier and less expensive they are to fix. Sealing is a preventative solution that helps you avoid the need for full slab replacement.
Improves Aesthetics
Cracked concrete makes your property look neglected. Sealing blends the damaged areas and improves the appearance of patios, driveways, sidewalks, and garage floors.
Extends Concrete Life
When properly maintained, sealed concrete can last decades longer, saving you time and money in the long run.
Common Areas Where Concrete Crack Sealing Is Needed
-
Foundation walls – to prevent basement leaks and structural compromise
-
Basement floors – to avoid moisture seepage and damage to, flooring above
-
Driveways and sidewalks – to maintain curb appeal and safety
-
Garage floors – to prevent oil, salt, and chemical damage
-
Patios and walkways – to protect outdoor living spaces from weathering
DIY vs. Professional Concrete Crack Sealing
Many homeowners consider sealing concrete cracks themselves. While DIY kits are available, they often offer temporary fixes at best.
Problems with DIY Concrete Crack Sealing:
-
Short lifespan of the repair material
-
Improper preparation of the crack
-
Inadequate tools or knowledge
-
Misidentification of structural vs. cosmetic cracks
-
No waterproofing protection
At Residential ResQ, we use industrial-grade sealants and proven methods tailored to the size, location, and cause of each crack, ensuring long-lasting and effective results.
Our Process: How Concrete Crack Sealing Works
Our professional process is designed for precision, durability, and minimal disruption:
Step 1: Inspection & Assessment
We begin with a thorough inspection to determine the cause, depth, and severity of the crack. This helps us identify whether the issue is structural or cosmetic and choose the best sealing solution.
Step 2: Cleaning and Preparation
The crack is cleaned of dirt, loose debris, and any previous sealant using high-powered vacuums or wire brushes. This ensures that the new sealant adheres properly.
Step 3: Crack Routing (if needed)
For larger or structural cracks, we use a router to slightly widen and deepen the crack. This allows the sealant to penetrate further and bond more securely.
Step 4: Injection or Filling
We inject the crack with a flexible polyurethane or epoxy sealant depending on the crack type and application.
-
Epoxy is used for structural repairs it hardens like concrete.
-
Polyurethane is ideal for waterproofing it stays flexible and expands to fill the space.
Step 5: Finishing and Clean-Up
The excess sealant is smoothed for a clean appearance. We ensure everything is sealed, safe, and ready for long-term performance.
Optional Step: Basement Waterproofing Integration
If water intrusion is a concern, we often integrate crack sealing into a full basement waterproofing strategy, including drainage solutions, sump pumps, and vapor barriers.
Frequently Asked Questions About Concrete Crack Sealing
How long does concrete crack sealing last?
Depending on the product used and environmental conditions, professional crack sealing can last 5 to 10 years or more.
Will sealing a crack fix a structural problem?
Sealing addresses surface issues and minor movement but is not a fix for serious structural problems. Our team will assess if further action, like underpinning or reinforcement, is needed.
Is concrete crack sealing waterproof?
Yes, when done professionally with the right materials like polyurethane, crack sealing offers effective waterproofing.
How much does it cost?
Costs vary depending on the size and location of the crack. Most homeowners find sealing to be a cost-effective alternative to slab replacement.
The Connection Between Crack Sealing and Basement Waterproofing
Crack sealing is often a first line of defense in preventing basement water problems. At Residential ResQ, we don’t just seal the surface we address the entire moisture control system.
When appropriate, we combine concrete crack sealing with:
-
Interior drainage systems
-
