Control Joint Sealants

DNA Restoring Concrete delivers expert control joint sealant solutions for commercial and residential properties throughout California's Central Valley.

Purposeful Joint Sealing That Protects Your Floor

At DNA Restoring Concrete, we specialize in professional control joint sealant applications that guard your concrete against cracking, spalling, and long-term structural damage. Founded in 2019 by Andrew Billings, who brings over 15 years of concrete expertise, our family-owned business has perfected the art and science of concrete protection.

Our premium control joint sealant services create floors that are:

• Crack-resistant by directing natural concrete shrinkage into controlled, protected joints
• Impact and load resistant so joint edges hold up under forklifts, pallet jacks, and foot traffic
• Moisture and debris resistant keeping water, dirt, and contaminants out of the slab
• Low-maintenance with long-lasting flexibility that reduces repeat repairs
• Seamlessly finished for a clean, professional look that doesn't disrupt your floor's overall design

Our Control Joint Sealant Process

1. Joint Inspection & Preparation

Every successful sealant application begins with a thorough inspection of existing joints for spalling, debris, or old failing sealant. Our diamond blade saws and HEPA-filtered vacuum systems clean and widen joints as needed while minimizing dust disruption to your environment.

2. Backer Rod Installation

For joints requiring additional depth control, we install closed-cell backer rod to establish the correct sealant depth-to-width ratio, ensuring proper flexibility and preventing three-sided adhesion that can cause premature failure.

3. Sealant Application

We apply a semi-rigid epoxy or flexible polyurethane/polyurea sealant matched to your floor's traffic and movement needs, filling each joint completely and tooling it to a clean, level finish flush with the surrounding slab.

4. Cure & Final Inspection

Once cured, every joint is inspected for full adhesion and a smooth, trip-free profile, giving you a protected floor ready for immediate traffic and long-term performance.
