Below-grade waterproofing is one of the most critical investments for a building owner. Particularly in South Florida, where ground moisture, hydrostatic pressure, and the region's unique soil & water table conditions place extraordinary demands on foundational structures, a properly specified below-grade system prevents water & moisture infiltration into foundational slabs, bridges the stress cracks that inevitably form over time, and when paired with effective water management techniques, ensures the entire below-grade building envelope remains leak-free. This significantly reduces the lifecycle maintenance costs that unaddressed moisture infiltration produce. Below-grade systems are applied to the negative or positive side of a structure depending on accessibility & exposure conditions; positive-side applications provide the most effective barrier, while negative-side crystalline & cementitious systems offer a reliable solution where exterior access is limited or impossible. Sheet-applied membranes, crystalline compounds, and drainage composites each play a specific role in a complete envelope strategy, and selecting the right system for the right condition is where technical expertise makes all the difference.
WATERPROOFING SERVICES
Waterproofing is one of the most critical, consequential, and rare disciplines in commercial construction. Formerly, this trade was loosely performed by painting contractors. Our expertise with coatings materials has made us a true waterproofing contractor, offering a cadence & attention to detail not previously found in the trade. A properly engineered & installed waterproofing system does not simply keep water out , it protects the structural integrity of a building from the ground up, extending the service life of concrete, steel, and masonry components. We operate across the full spectrum of building envelope protection, from below-grade foundations to above-grade decks & fountains. We only deliver complete, engineered solutions for every surface where water meets structure.
WATERPROOFING SOLUTIONS INFO
At Bay to Bay, our waterproofing capabilities extend well beyond conventional membrane application. We specialize in cold fluid-applied roof deck systems & specialty roofing solutions, in-ground & elevated pools, pedestrian & vehicular traffic coating membranes, expansion joint customization & repair, and epoxy injection for structural crack repair and water infiltration remediation. Every waterproofing system we design & install is specified to the demands of the environment, the exposure conditions, and the long-term performance requirements of the structure, because in waterproofing, there is no margin for error & no acceptable standard below complete protection.
BELOW-GRADE WATERPROOFING
ABOVE-GRADE WATERPROOFING
Above-grade waterproofing addresses the prevention of water infiltration into a structure above ground level, a fundamentally different challenge from below-grade systems, as above-grade applications must contend with continuous exposure to weather, UV degradation, thermal movement, and the relentless cycle of expansion & contraction that Florida's climate demands of exterior surfaces. Where below-grade systems combat hydrostatic pressure, above-grade systems must perform against driving rain, ponding water, and the structural movement that occurs in elevated & exposed conditions. Among the most technically demanding above-grade applications are above-ground pools, fountains, and planters. These structures experience exceptional movement, constant water contact, and the kind of stress that standard waterproofing systems simply cannot accommodate. Our above-grade pool shell waterproofing systems feature Notice of Acceptance approvals & 20-year watertight warranties, and are flexible polyurethane membranes specifically engineered to flex & recover with the excess structural movement inherent in above-ground pool construction, ensuring a watertight envelope that performs for the life of the structure.
TRAFFIC & PEDESTRIAN COATINGS
Commercial traffic coatings are specialized elastomeric waterproofing & protective membrane systems engineered for the most demanding vehicular & pedestrian environments in commercial construction. This includes parking garages, walkways, balconies, and exposed decks, where water infiltration, chemical exposure, and continuous traffic loads combine to create conditions that conventional coatings cannot withstand. These systems are specifically designed to bridge cracks, flex with structural movement, and create a seamless, continuous waterproof barrier that protects the concrete substrate from moisture penetration, freeze-thaw cycling, chemicals, and the cumulation of heavy traffic over time. Traffic coating systems, composed of epoxy base coats, polyurethane or polyaspartic membranes, and aggregate broadcast topcoats, deliver both waterproofing performance & surface durability in a single system, significantly extending the service life of the surface. In parking structures & exposed decks where uncoated concrete surfaces are subject to accelerated deterioration from water infiltration & chemicals, a properly spec'd & installed traffic coating system is essential to the long-term structural integrity & lifecycle cost management of the surface.
EXPANSION JOINT SERVICES
Expansion joints are a critical & often underestimated component of any concrete structure. These engineered assemblies are designed to absorb thermal expansion, contraction, and structural movement that would otherwise result in uncontrolled cracking & water infiltration throughout a building's service life. Found throughout parking structures, bridges, building facades, and elevated decks, expansion joints are particularly vulnerable in older & remodeled structures where dated materials, outdated installation methods, or simply decades of movement have compromised their effectiveness. We specialize in the full scope of expansion joint services: new installation, complete replacement, repair, and fully custom solutions, with expertise in pre-compressed, winged, closed-cell, and soft rod joint systems, each selected & specified to the precise movement, exposure, and waterproofing requirements of the structure. Repairing or replacing a failed expansion joint involves complete removal of the compromised material, thorough joint preparation, and the installation of a modern, flexible system engineered to perform for decades, restoring the structural & waterproofing integrity of the joint & protecting the building envelope from water infiltration & accelerated deterioration that failed joints inevitably cause.
IN-GROUND & ELEVATED POOL SOLUTIONS
Pool waterproofing is a technically demanding application, a discipline that requires an intimate understanding of the unique structural, chemical, and environmental stresses that pools place on waterproofing systems. Concrete & gunite pool shells are inherently porous, subject to continuous chemical exposure from treatment, and experience structural movement from hydrostatic pressure, thermal cycling, and soil shifting. These conditions demand a system engineered specifically for the application rather than general purpose products. We waterproof both in-ground & elevated pools, addressing the full range of pool shell, bond beam, and deck waterproofing requirements with systems selected for long-term chemical resistance, flexibility, and watertight performance. Elevated pool structures present the greatest challenge & experience greater structural movement than in-ground pools, requiring highly flexible polyurethane membrane systems specifically engineered to flex & recover with the excess movement inherent in these structures. From new construction waterproofing to the remediation of leaking or deteriorating existing shells, we deliver complete pool waterproofing solutions that protect the structure, preserve the investment, and perform for the life of the pool with Notice of Acceptance approvals & 20-year watertight warranties.
PLAZA DECK & PLANTER REPAIR
Plaza deck waterproofing & repair is a multi-phase discipline that begins with a thorough assessment & remediation of the existing substrate. Addressing cracks, spalling, deteriorated concrete, and drainage deficiencies is key before any waterproofing system is applied. The integrity of the surface preparation is everything in plaza deck work, as a waterproofing membrane is only as reliable as the substrate it is bonded to, and any unaddressed structural issues will compromise even the most advanced system over time. Our plaza deck waterproofing systems span the full range of proven tech, including cold-applied polyurethane membranes for inverted & tile-over applications, hot-applied rubberized asphalt for large seamless installations, sheet-applied membranes for continuous bonded barriers, and liquid-systems for complex geometries & detail-intensive conditions, each selected & spec'd to the structural demands, drainage requirements, and long-term performance expectations. The result is a complete, engineered waterproofing solution that protects the structure below, manages water effectively at the surface, and delivers the service life the investment demands.
EPOXY INJECTION SYSTEMS
Epoxy injection is one of the most precise & effective methods available for the structural repair & waterproofing remediation of cracked concrete. This process goes beyond surface treatment to address water infiltration & structural compromise at its source. By injecting a specialized epoxy resin under controlled pressure directly into cracks & voids within the concrete matrix, the system fills the full depth of the crack, chemically bonds the concrete back together, and creates a permanent, waterproof barrier that prevents future water intrusion & restores the structural integrity of the affected member. Epoxy injection is suitable for a wide range of commercial & structural applications, including parking structures, foundations, basements, tunnels, tanks, retaining walls, and any concrete element where active leaking, crack propagation, or moisture infiltration is compromising the performance or longevity of the structure. Our epoxy injection is performed as a precision process, with proper crack mapping, port placement, and resin selection specific to the crack width, depth, moisture condition, and structural requirements of each individual repair.
WATER-FIXTURE & FOUNTAIN SCOPES
Water feature & fountain waterproofing is a detail-driven discipline that demands both technical waterproofing expertise & a craftsman's attention to custom conditions. Unlike pools or conventional concrete surfaces, fountains & decorative water fixtures involve complex geometries, architectural details, unique material transitions, and the challenge of waterproofing around the plumbing, mechanical equipment, and utility penetrations that live within structure, each one a potential point of failure if not properly addressed. Our approach to water feature waterproofing begins with the substrate itself, ensuring the water moves exactly where it is designed to. Building up concrete curbs, forming custom coves at material angle transitions to eliminate the stress points where flat-to-vertical surfaces meet, and ensuring all plumbing & equipment penetration is fully sealed and protected at its point of entry & exit through the waterproofed substrate is covered. Liquid-membranes, waterproofing coatings, and specialty liners are selected based on the specific material, exposure conditions, and design requirements of each feature, delivering a fully watertight system that protects both the structure and its mechanical systems.
COLD-FLUID APPLIED ROOF DECKS
Cold fluid-applied roofing systems are liquid waterproofing membranes, applied without heat, that offer a safe, versatile, and highly effective alternative to traditional hot-applied roofing methods, all while eliminating the logistical challenges & open-flame concerns that hot-applied systems present in occupied or sensitive environments. Unlike conventional roofing materials that rely on overlapping layers & seams as their primary water barrier, cold fluid-applied systems cure into a fully monolithic, seamless membrane that bonds directly to the substrate, creating a continuous waterproof envelope with no joints, overlaps, or seams where water can infiltrate. This direct substrate bond is critical as it prevents lateral water migration beneath the membrane, meaning that even in the event of a puncture or storm damage, water cannot travel beneath the system & compromise the broader roof assembly. Suitable for both new construction & roof restoration applications, cold fluid-applied systems are among the most adaptable & long-performing roofing solutions available. Every system is specified to the structural, drainage, and exposure requirements of the specific roof it is protecting.
Specialty Roofing Applications
Specialty roofing encompasses the full range of roofing applications that fall outside the scope of conventional systems, such as complex roof designs, unique substrate conditions, and performance-specific requirements that demand advanced materials, specialized installation techniques, and a level of waterproofing expertise that standard roofing contractors are not equipped to provide. Where traditional roofing systems rely on overlapping materials & mechanical fastening to manage water, specialty roofing waterproofing systems use advanced membranes, coatings, and sealants to create fully continuous, watertight barriers over some of the most challenging roof geometries and substrate conditions in commercial construction, including tile, metal, and pedestrian deck applications where conventional approaches fall short. Our specialty roofing capabilities address the unique waterproofing demands of each system type, from the seam & penetration detailing critical to metal roof waterproofing, to the membrane & setting bed systems required beneath tile & paver installations, to the traffic-bearing waterproofing membranes that pedestrian roof decks demand. Every specialty roofing system we install is specified to the structural, drainage, aesthetic, and long-term performance requirements of the specific application. When the roof is anything but conventional, the waterproofing approach needs to match.
Full roof replacement
Full roof replacement, or complete tear-off, represents the convergence of Bay to Bay's entire waterproofing expertise & our full-scale General Contractor capabilities delivered as a single, comprehensive scope of work. Where partial repairs & restoration systems address isolated issues, a full roof replacement starts from the deck up, the complete removal of all existing roofing components including shingles, underlayment, flashing, and any deteriorated or compromised decking, followed by the installation of an entirely new roofing system engineered for the specific structural, climatic, and performance demands of the building.
