Parking garage concrete deteriorates for several reasons, including moisture intrusion, reinforcing steel corrosion, structural movement, and years of vehicle traffic. When moisture reaches embedded reinforcing steel, corrosion can cause the surrounding concrete to crack, delaminate, or break away. Structural concrete repair addresses damaged areas and helps prevent further deterioration. When moisture intrusion contributes to concrete deterioration, our vehicular traffic coating systems can provide additional waterproof protection for parking deck surfaces.

Rocking or movement between parking deck panels can occur when welded connections between precast double-tee concrete sections fail. These connections help transfer loads between adjacent panels, and damaged connections may allow noticeable movement as vehicles pass over the joint.

Depending on the condition of the structure and engineering requirements, repairs may include carbon fiber T-biscuit reinforcement systems bonded into the concrete across the flange joint. These systems can help restore load transfer and stabilize movement between adjacent precast double-tee panels without requiring complete panel replacement.

Yes. Many concrete problems can be repaired without replacing an entire structural component. Depending on the extent of deterioration, repairs may involve removing damaged concrete, treating exposed reinforcing steel, installing repair materials, performing structural crack injection, or adding reinforcement. Severely damaged components may require partial or complete replacement based on an engineering evaluation.

Yes. Structural epoxy injection can be used to bond certain cracks in concrete beams, slabs, columns, and other structural components when conditions are suitable. However, not every crack should be injected. Active movement, water intrusion, and underlying structural problems must be evaluated before selecting a repair method. Other injection materials or reinforcement systems may be more appropriate depending on the conditions.

Falling concrete, overhead spalling, and exposed reinforcing steel should be evaluated promptly because they may create hazards for vehicles and pedestrians below. Repairs can involve removing unsound concrete, assessing and treating corroded reinforcement, replacing deteriorated concrete, and applying protective systems where appropriate. Areas presenting an immediate falling-debris hazard should be restricted until they can be evaluated and made safe.

The appropriate repair method depends on the type of structure, extent of deterioration, cause of damage, and whether structural movement or corrosion is present. The Waterproof Group evaluates visible conditions and works with structural engineers when necessary to determine appropriate repairs. Solutions may include concrete restoration, structural crack injection, carbon fiber reinforcement, precast connection repairs, or replacement of deteriorated concrete, followed by protective waterproofing systems when needed. For projects involving deck joints and deteriorated sealants, we also provide expansion joint and sealant systems to help manage movement and water intrusion.
