Commercial Roof Waterproofing
From hot rubber roof application down to below-grade waterproofing, we protect buildings with a full envelope approach.
Waterproofing Beyond the Roof Itself
Commercial waterproofing at Kodiak covers the entire building envelope, not just the membrane. Parking structures, decks, foundations, exterior walls, and roof-to-wall transitions all get the same standard of protection under one contract, not a separate call to a different specialty contractor.
Hot Rubber Application
Hot rubber application is one of the most durable commercial roof waterproofing methods available, and Kodiak applies it across roofing, below-grade, and exterior wall surfaces.
Find the Source of a Leak Before It Damages Your Building
Reach out to Kodiak if you suspect a below-grade or exterior leak. Commercial roof waterproofing starts with locating the actual source, not a guess.
Pressure Injection Waterproofing for Active Leaks
When water has already found its way into a below-grade structure, pressure injection is often the most direct fix, sealing the problem without excavating a foundation wall or tearing into a finished, occupied space above it.
Sealed From the Inside, Not Covered on the Surface
Kodiak injects polyurethane sealant directly into the crack or joint where water is entering, closing the actual path instead of masking it with a surface coating that won’t stop water from finding a different way in.
Built to Chase the Leak Until It's Fully Sealed
Water tests new paths once the first one closes, so a full seal sometimes takes two or three visits. Kodiak treats each return visit as part of the job, targeting the new path directly until the structure is completely dry.
Frequently Asked Questions
What other waterproofing methods does Kodiak use besides hot rubber and pressure injection?
Fluid-applied coatings, air barriers, and joint sealants are also part of Kodiak’s waterproofing scope, selected based on the specific surface and exposure involved.
What are the signs that below-grade waterproofing is failing?
Efflorescence, a white chalky residue on concrete, along with a musty smell or damp walls in a below-grade space, are early signs worth having Kodiak evaluate before they turn into an active leak.
How long does hot rubber waterproofing typically last?
A properly installed hot rubber system can perform for decades with the right drainage and maintenance, which is part of why Kodiak still uses it for high-durability applications.
How do I know if I need waterproofing instead of a roof repair?
If the leak is coming from below-grade, an exterior wall, or a roof-to-wall transition rather than the roof membrane itself, Kodiak will point you toward waterproofing instead of a roof repair.
