Pool Mastic & Expansion Joints
Specialty installation that protects concrete from movement and water damage.
Pool mastic and expansion joints are where North Texas Mastic began — and they remain our core specialty. Properly installed expansion joints protect your pool deck, coping, sidewalks, and driveways from cracking, movement damage, and water intrusion.
​
We remove failed or deteriorated material and install new joints using proper preparation methods, backer rod, and high-quality sealants designed for long-term flexibility and durability.

​​
Clean joints aren’t just about appearance — they’re critical to protecting the concrete around them.
Residential and commercial projects welcome. We work with homeowners, builders, and developers across North Texas.
