In preserving parking facilities from unrelenting water, temperature fluctuations, and environmental degradation, Knollmeyer Building Corp offers proven solutions that stand the test of time and traffic. As the preferred choice for parking garage waterproofing North Andover building owners turn to, we’ve spent decades perfecting attention to detail on every project.
Our specialists are experts in cutting-edge waterproofing systems designed specifically for concrete parking garages, delivering lasting durability and protection from moisture, freeze-thaw cycles, and de-icing salts.
From membrane coatings and joint seals to drain systems and structural repairs, we tailor each solution to your garage’s exact specifications.
The result: a superior, low-maintenance system that extends garage life, safeguards your investment, ensures user safety, and preserves overall structural integrity.
The Importance of Waterproofing in Parking Garages
Parking garages face extreme environmental exposure year-round. Rain, snow, deicers, automotive fluids, and freeze-thaw weathering cause ongoing stress to concrete surfaces and structural elements.
These stressors can penetrate finishes, corrode rebar, and cause cracking, spalling, and deterioration. Left unchecked, the damage compromises structural safety for vehicles and pedestrians alike.
According to the Federal Highway Administration (FHWA), water infiltration is a major cause of structural degradation in American concrete parking facilities. Moisture accelerates rebar corrosion, undermines concrete integrity, and shortens the lifespan of these structures.
When damage is allowed to develop, emergency repairs can cost many times more than proactive waterproofing. Installing a comprehensive waterproofing system not only extends garage life but also ensures compliance with building and safety codes.
Common Parking Garage Issues
- Water Intrusion: Moisture enters through cracks, faulty expansion joints, or poor drainage, leading to corrosion and material failure.
- Concrete Spalling: Freeze-thaw cycles cause water to expand and contract within concrete, leading to flaking, surface wear, and reduced structural capacity.
- Rusted Reinforcement: Water exposure causes rebar to rust and expand, creating internal cracks that weaken the structure.
- Surface Wear: Daily vehicle traffic, tire abrasion, and chemical exposure gradually erode surface materials, reducing traction and accelerating deterioration.
Our Waterproofing Solutions
- Surface preparation and cleaning
- Crack and joint sealing
- Concrete resurfacing and repair
- Waterproofing membranes for vehicular traffic
- Elastomeric coating systems
- Urethane and epoxy injection
- Drainage system improvements
- Basement waterproofing for below-grade garages
Each system is customized based on the age, design, and environmental exposure of your facility.
Our Proven Process
- Inspection and Evaluation: We begin with a comprehensive building analysis—visual inspection, moisture scans, and substrate assessments—to locate deficiencies and form a targeted waterproofing plan.
- Surface Preparation: Using shot blasting, high-pressure washing, and scarifying, we remove contaminants like salts, oils, and coatings to ensure optimal adhesion of waterproofing materials.
- Precision Application: Membranes and sealants are applied to exact manufacturer and industry specifications—layer thickness, overlap, curing time, and temperature are all carefully controlled.
- Final Testing: We conduct adhesion tests, moisture checks, and visual inspections to confirm full system performance before sign-off.

FAQs
How often should I waterproof my garage?
Every 5–10 years, depending on exposure, usage, and material wear.
Can you waterproof a damaged garage?
Yes, but existing damage must be repaired first.
How long does the process take?
Typically 1 to 3 weeks, depending on garage size and repair complexity.
Do you waterproof below-grade garages?
Yes. We offer basement sealing, sub-slab drainage, and moisture barriers for underground garages.
