Expansion joints and control joints need periodic maintenance to provide longevity for your concrete parking lot. Failing joint sealant is the number one cause of cracks and deteriorating concrete. Service starts by removing the old sealant and backing material from joints. Once all debris and material have been cleaned by saw cutting and sweeping, we will install bond breaker or backer rod in base of joint, as needed. Finish by injecting Urethane or Silicone self-leveling sealer.
