When it comes to protecting your structure from long-term water damage, exterior foundation waterproofing is the first and most critical line of defense. At 1 Dry Basement, we provide professional residential and commercial waterproofing solutions that are built to last—because keeping water out is always better than dealing with it after the fact.
Exterior Waterproofing: Stop Water Before It Enters
Exterior waterproofing involves sealing the outside of your foundation to prevent moisture from ever reaching your basement or crawlspace walls. This method is especially effective for new construction, but it can also be retrofitted on existing homes and buildings where water intrusion is a recurring problem. We use a combination of modern sheet membrane systems, liquid-applied waterproof coatings, and foundation drainage to fully protect below-grade walls.
Our process includes:
Excavation around the foundation perimeter Cleaning and prepping the foundation walls Application of a self-adhering sheet membrane or liquid rubber waterproofing Installation of a drain board or dimple mat for added drainage Application of 2" rigid foam board insulation for protection and energy efficiency Finishing with a French drain or footing drain system connected to a sump pump or daylight discharge This layered system ensures that water is not only blocked but also redirected safely away from your foundation.
Our go-to products include
Henry Blue Skin Waterproofing Membrane, GCP Bituthene 3000, and Blueskin WP200, along with heavy-duty drainage boards. These materials are proven to withstand hydrostatic pressure and long-term exposure to moisture, making them ideal for both residential and commercial applications. Whether you're dealing with hydrostatic pressure, surface runoff, or poor grading, our exterior foundation waterproofing services are customized for each property’s specific needs.
If you're planning new construction, there’s no better time to get foundation waterproofing done right—before moisture becomes a problem. At 1 Dry Basement, we work directly with homeowners, builders, and general contractors to install long-lasting exterior waterproofing systems during the most critical stage of the build.
We understand timelines, coordination, and what’s at stake on a job site. That’s why our team is committed to seamless scheduling, clean execution, and communication you can count on. From self-adhering membranes to full drainage assemblies, we use only trusted products like Henry Blueskin, GCP Bituthene, and heavy-duty drainage boards that meet industry specs and builder expectations.
Including professional exterior waterproofing as part of your build plan adds lasting value, protects structural integrity, and helps ensure peace of mind for your future buyers or clients.
