Commercial Waterproofing

Water intrusion represents one of the most significant threats to commercial buildings, capable of causing extensive structural damage, compromising building integrity, and creating hazardous conditions for occupants. From foundation deterioration to mold growth and electrical system damage, the consequences of inadequate waterproofing can be devastating both structurally and financially. At Tri-State Waterproofing, we’ve spent decades helping commercial property owners protect their investments through effective waterproofing solutions. As a commercial waterproofing contractor, in this comprehensive guide, we will help you explore seven proven commercial waterproofing approaches that prevent costly structural damage and extend the lifespan of your building. The High Stakes of Commercial Water Damage Before dipping into clear solutions, it’s essential to understand what’s at risk when commercial buildings lack appropriate waterproofing: Financial Impact Water damage in commercial buildings carries significant financial consequences: “The cost of proper waterproofing is minimal compared to the expense of addressing water damage after it occurs,” explains a commercial property specialist at Tri-State Waterproofing. “We typically find that preventative waterproofing represents just 2-5% of what remediation and repairs would cost after significant water intrusion.” Structural Consequences Water infiltration attacks a building’s structural integrity in multiple ways: Health and Safety Concerns Beyond structural issues, water intrusion creates serious health and safety risks: Solution #1: Foundation Waterproofing Systems The foundation represents your building’s first string of protection against groundwater intrusion. Comprehensive foundation waterproofing is essential for preventing water migration into basements, crawl spaces, and ground-floor areas. Key Components: Application Considerations: For existing buildings, foundation waterproofing typically requires excavation to access exterior foundation walls. While this represents a significant investment, it provides the most comprehensive protection against groundwater intrusion. For new construction, as a commercial waterproofing contractor, we recommend that foundation waterproofing should be integrated into the building design from the beginning, with careful attention to membrane selection, drainage provisions, and connection details. Solution #2: Exterior Wall Waterproofing Commercial building envelopes must effectively manage water that contacts exterior walls through rainfall, splashing or wind-driven moisture. Proper exterior wall waterproofing controls water infiltration while allowing the wall system to breathe and remove any trapped moisture. Key Components: Application Considerations: As a commercial waterproofing contractor, exterior wall waterproofing can be incorporated during new construction or renovation projects. For existing buildings, options include coating systems, injection treatments, and replacement of failed sealants and flashings. The appropriate approach depends on the wall construction type (masonry, concrete, EIFS, metal panel, etc.), local climate conditions, and building exposure. Solution #3: Roof Waterproofing and Drainage The roof represents the largest horizontal surface exposed to precipitation and is often the source of the most significant water intrusion issues in commercial buildings. Comprehensive roof waterproofing combines multiple elements to ensure water is effectively managed. Key Components: Application Considerations: Roof waterproofing options vary based on roof type, building use, climate conditions, and budget considerations. For existing buildings, options range from complete roof replacement to restoration systems that extend the life of the current roof while improving waterproofing performance. Solution #4: Below-Grade Waterproofing Below-grade spaces in commercial buildings present unique waterproofing challenges due to constant ground moisture exposure and hydrostatic pressure. Effective below-grade waterproofing requires specialized systems designed for these demanding conditions. Key Components: Application Considerations: For new construction, as a commercial waterproofing contractor, we recommend that positive-side (exterior) waterproofing provide the most effective protection and should be incorporated into the building design. For existing structures, negative-side (interior) waterproofing offers a practical solution when exterior excavation isn’t feasible. The appropriate system depends on groundwater conditions, soil composition, building use, and accessibility. Solution #5: Plaza Deck and Podium Waterproofing Many commercial buildings incorporate occupied spaces below plaza decks, parking areas, or landscaped podiums. These areas require specialized waterproofing systems that can withstand traffic, planting, or other surface uses while providing complete protection to the spaces below. Key Components: Application Considerations: Plaza and podium waterproofing must be carefully integrated with structural design, landscape architecture, and building systems. The appropriate system depends on the intended surface use, structural design, climate conditions, and maintenance considerations. For existing plazas, rehabilitation options range from targeted repairs to complete reconstruction, depending on the condition of the existing waterproofing and the extent of any damage. Solution #6: Joint and Penetration Treatments Building joints and penetrations represent vulnerable points in any waterproofing system. Proper treatment of these areas is essential for maintaining the integrity of the overall waterproofing approach. Key Components: Application Considerations: Joint and penetration treatments must be compatible with adjacent waterproofing systems and accommodate expected movement. The appropriate solution depends on joint width, movement expectations, exposure conditions, and accessibility for future maintenance. For existing buildings, joint rehabilitation often provides a cost-effective approach to resolving water intrusion without disturbing intact waterproofing areas. Solution #7: Preventative Maintenance Programs Even the best waterproofing systems require ongoing maintenance to deliver their full performance potential. Preventive maintenance programs identify & address issues before they lead to water intrusion and structural damage. Key Components: Application Considerations: As a commercial waterproofing contractor, we said that effective preventative maintenance programs should be tailored to the specific waterproofing systems in place, local climate conditions, building use, and owner resources. Programs typically include a combination of owner-performed basic maintenance and professional inspections and services.
