How do you determine the right waterproofing system for a building?

Determining the right waterproofing system for a commercial building requires a comprehensive assessment of several interconnected factors. The process typically begins with a detailed inspection of the building’s structure and envelope, including walls, roofs, below-grade areas, joints, and surrounding site conditions. For New England properties, special attention is paid to freeze-thaw cycles, heavy rainfall, snow, ice, and salt exposure, all of which can accelerate deterioration and water ingress if not properly addressed.

Professionals evaluate the type and age of construction, the building’s intended use, and historical performance issues like leaks or moisture damage. Different materials—such as concrete, masonry, stone, or EIFS—may each need distinct solutions. High-traffic areas (like parking garages or plaza decks), historic facades, or occupied spaces may call for specialized systems to ensure long-term protection, compliance, and minimal disruption.

Next, assessment includes identifying sources of water intrusion, potential movement or settlement cracks, failed expansion joints, and vulnerable details such as parapets, balconies, or transitions between materials. For existing moisture problems, water testing or infrared scanning can help locate hidden leaks or saturated materials.

Only after this evaluation can the correct waterproofing approach be specified. This might include fluid-applied membranes, sheet systems, elastomeric coatings, sealants, or drainage systems, each selected based on compatibility with the building, climate demands, and project goals. Proper surface preparation, professional installation, and periodic maintenance are all critical to avoid premature failure and protect the building for decades.

In summary, the right waterproofing system is not a one-size-fits-all answer. It depends on building design, condition, regional weather challenges, use requirements, and expected lifespan.
