Concrete Crack Repair: Professional Sidewalk Maintenance by The Sidewalk Guy

​

Crack repair isn’t just cosmetic — it’s essential preventative maintenance that protects your sidewalk from further damage and costly replacements.

At The Sidewalk Guy, we use industry-leading methods and high-quality materials to deliver long-lasting repairs that blend beautifully into your existing sidewalk.

Our Proven Crack Repair Process

​

 

1. Precision Cutting

• We use a specialized crack-chasing disk to carefully cut along the crack, creating a consistent width and depth.
   

• This prepares the crack for proper sealant bonding and ensures the repair falls within the performance specifications of the sealing materials.
   

 

2. Depth Management

• If a crack is deeper than specified, we first fill deep sections with clean sand.
   

• This ensures a consistent sealant depth and prevents excessive material use or uneven curing.
   

 

3. Backer Rod Installation

• We insert a foam backer rod into the prepared joint.
   

• This critical step prevents three-sided adhesion, allowing the sealant to flex properly with temperature changes and reducing the risk of premature cracking or failure.

4. High-Performance Sealant Application

• For horizontal surfaces, we use self-leveling polyurethane sealants designed for sidewalks and flatwork.
   

• For sloped areas, such as ramps or driveway crossings, we use semi-self-leveling sealants like Tremco Dymonic® 45SSL to ensure excellent flow without sagging.
   

• These flexible, durable sealants are designed to handle Colorado’s freeze-thaw cycles and temperature swings.
   

 

5. Custom Color Blending — Our “Secret Sauce”

• For a superior, professional finish, we create a custom blend of sand and exterior-grade additives to match the color and texture of your existing concrete.
   

• This extra step helps the repair blend seamlessly into the sidewalk — reducing the visibility of the crack repair and maintaining the curb appeal of your property.
