What is Expansion Joint Repair?
Expansion joints are essential in any structure, allowing materials to expand and contract with temperature fluctuations and other environmental factors. However, these joints can become susceptible to leakage and seepage over time, causing damage to your building. Expansion joint repair involves sealing these joints to prevent water ingress and structural damage.
