Concrete & Joint Sealants
Concrete joint sealants help keep water out of the cracks and joints in your concrete, reducing erosion beneath the slab and helping prevent future settling. DBS Repair uses NexusPro® to seal joints and cracks and SealantPro™ to protect the concrete surface, helping driveways, sidewalks, patios, and other concrete areas last longer through Minnesota’s changing weather.
NexusPro®: Long-Lasting Concrete Joint Sealants for Cracks and Control Joints
Many store-bought urethane caulks can crack, dry out, or lose flexibility over time, leading to ongoing maintenance and repeated repairs. DBS Repair uses NexusPro®, a silicone-based sealant designed specifically for concrete joints and cracks. Engineered to stay flexible through Minnesota’s changing weather conditions, it helps create a long-lasting seal that protects concrete surfaces from water intrusion and further deterioration.
Before sealing, cracks are carefully cleaned and prepared to help the repair last. DBS Repair installs a non-absorbent backer rod, applies NexusPro®, and finishes the repair with a light layer of native sand for a clean, natural appearance that blends with the surrounding concrete. Properly sealed cracks also help prevent weeds from growing through joints and openings.


SealantPro™: Permanent Protection for Concrete Joint Sealants and Surfaces
Water is one of the leading causes of concrete damage. As moisture enters untreated concrete, repeated freeze-thaw cycles can lead to cracking, surface flaking, discoloration, and premature wear. While many store-bought sealers require regular reapplication, SealantPro™ provides long-lasting protection with a single application.
Developed by Supportworks, SealantPro™ bonds directly with the concrete to help protect against water, dirt, and other contaminants. It dries quickly, works with new and existing concrete, and helps extend the life of driveways, sidewalks, patios, and other concrete surfaces. When combined with concrete joint sealants, DBS Repair provides a more complete solution for protecting concrete from moisture-related damage and reducing future repair needs.

DBS Repair Sealants vs. Store-Bought Products
DIY sealants may seem like a cost-effective option at first, but many products can crack, wear out, or lose their seal over time, leading to ongoing maintenance and repeated applications. Professional-grade sealants used by DBS Repair are designed for long-term performance, helping protect concrete joints and surfaces from water intrusion, weather exposure, and everyday wear. By addressing the problem with the right materials from the start, homeowners can often avoid more extensive concrete repair or concrete leveling needs in the future.
DIY Concrete Sealant Approach
Big-Box Urethane Caulk & Sealers
Urethane caulk is prone to cracking, bubbling, and drying out, so joints need resealing sooner than expected. Surface sealers are messy to apply, must be redone every few years, get expensive over time, and are often incompatible with new concrete.
Recommended Concrete Sealant Solution
NexusPro® + SealantPro™
NexusPro® seals cracks and joints with UV-resistant silicone that handles extreme temperatures and cures in about an hour. SealantPro™ protects the entire surface permanently in one coat and costs less over time because it never needs reapplication.

What to Expect From Our Concrete Joint Sealants Process
1.
Free on-site inspection and estimate
Every project begins with a detailed inspection by a DBS Repair specialist. We evaluate cracks, control joints, surface wear, and signs of water-related damage to determine the condition of your concrete. This allows us to identify areas that may be vulnerable to future deterioration and recommend the most effective sealing solution. After the inspection, you’ll receive a written proposal outlining the recommended work, products, and expected results so you can make an informed decision about protecting your concrete investment.
2.
Crack and joint preparation
Before any concrete joint sealants are applied, a DBS Repair specialist inspects the cracks, control joints, and overall surface condition. This helps determine where water may be entering, where joints need protection, and whether the slab needs additional concrete repair or sealing. After the inspection, you’ll receive a written proposal with the recommended scope of work for protecting your concrete. Professional concrete joint sealants help protect cracks and control joints from water intrusion, soil erosion, and freeze-thaw damage.
3.
NexusPro® application
Once the concrete has been prepared, DBS Repair applies NexusPro® to cracks and control joints. Unlike many store-bought products that can become brittle over time, NexusPro® is designed to remain flexible through seasonal temperature changes and harsh weather conditions. The sealant helps prevent water from entering joints and cracks, reducing the risk of erosion beneath the slab and helping protect the concrete from future damage. This flexible seal plays an important role in maintaining the condition and appearance of concrete surfaces.
4.
SealantPro™ surface coat
After the sealant is installed, repairs are detailed with a light layer of native sand to create a more natural, uniform appearance. This finishing step helps treated areas blend more closely with the surrounding concrete while maintaining a clean, professional look. In addition to improving appearance, properly sealed joints and cracks help reduce the likelihood of weeds growing through openings in the concrete, making driveways, sidewalks, and patios easier to maintain over time.
5.
Same-day use
To provide additional protection, DBS Repair applies SealantPro™ across the concrete surface. This advanced concrete sealer bonds with the concrete and helps protect against water, dirt, salt, oil, and other contaminants that can contribute to premature wear. Unlike many traditional sealers that require frequent reapplication, SealantPro™ provides long-lasting protection with a single application. It can be used on driveways, sidewalks, patios, garage floors, and other concrete surfaces to help extend their lifespan and maintain their appearance.
