Water intrusion doesn’t just affect floors—it can compromise walls and below-grade structures as well. Whether you’re safeguarding a foundation, retaining wall, or elevator pit, our team is equipped with the systems and skill to get the job done right.
What Are Vertical & Below-Grade Systems?
Vertical and below-grade waterproofing involves applying specialized materials to surfaces exposed to consistent or periodic moisture. These systems are designed to prevent water infiltration through foundation walls, basement levels, exterior retaining walls, and other vertical concrete or masonry structures. Without proper waterproofing, these areas are highly vulnerable to water damage, which can lead to mold growth, structural deterioration, and costly repairs over time.
At ArtDeck, Inc., we use a range of high-performance waterproofing membranes and coatings—including fluid-applied, sheet-applied, and bentonite systems—tailored to the specific site conditions and project requirements. Our expert technicians ensure thorough surface preparation, precise installation, and attention to detail at every step to create a durable, watertight barrier. We work closely with contractors, engineers, and property owners to deliver solutions that meet building codes, environmental demands, and long-term performance goals. Whether for new construction or retrofit projects, our vertical and below-grade waterproofing systems provide reliable protection against hydrostatic pressure, moisture intrusion, and weather-related wear, safeguarding your investment from the ground up.
Common Applications Include:
- Foundation walls and basements
- Underground garages and vaults
- Retaining walls
- Planter boxes and garden walls
- Elevator pits and mechanical rooms
Proper waterproofing of these areas is crucial to maintaining structural integrity and preventing mold, mildew, and long-term water damage.
