Basement Waterproofing in Arlington, VA
Challenge
In Arlington, VA, a homeowner faced a recurring and stressful issue—basement flooding every time it rained. The problem was twofold. First, water was entering through a basement door located in a narrow rear alley, where rainwater naturally collected and flowed toward the home. This low point in the property created a direct path for water to seep under and around the door during even moderate storms.
Second, and equally concerning, was the fact that water was also penetrating through the foundation walls. Over time, hydrostatic pressure and poor drainage around the home’s perimeter had caused water to seep through small cracks and weak spots in the concrete. This led to widespread moisture in the basement, damp floors, and visible signs of water damage.
The combination of surface water intrusion and foundation wall leaks made the basement musty, uncomfortable, and completely unusable. The homeowner had grown increasingly concerned about mold growth, indoor air quality, and long-term damage to the home’s structure and foundation.
After trying various temporary fixes with no lasting results, the homeowner reached out to NV Waterproofing and Foundation Repair, seeking a trusted and permanent solution for basement waterproofing in Arlington, VA.
Solution
To address the severe and ongoing water intrusion issues at this Arlington, VA home, NV Waterproofing and Foundation Repair implemented a comprehensive basement waterproofing solution. Our goal was to stop water from entering through both the alley-facing basement door and the foundation walls, and to protect the home long-term from moisture, flooding, and structural damage.
We began by targeting the most visible source of flooding: rainwater pouring in through the basement door located in a rear alley. To stop surface runoff from reaching the door, our team installed a trench drain at the entry point. This drain collects and redirects water away from the home, preventing direct intrusion at one of the most vulnerable spots on the property.
During the inspection, we also identified water entering through a basement window well. To solve this, we installed a WellDuct window drain system, which connects the window well to the interior WaterGuard drainage system. This setup allows water that collects in the well to safely drain away before it can leak into the basement, keeping both the walls and interior space dry.
Next, we installed the WaterGuard interior drainage system, a below-floor channel that collects any water seeping in through the foundation walls due to hydrostatic pressure or small cracks. This water is then directed to a sump pump before it can affect the basement floor or living area.
To stop ongoing wall moisture and reduce the risk of mold, we applied the CleanSpace vapor barrier along the basement walls. This heavy-duty liner not only prevents water vapor from entering but also gives the space a clean, finished look. It's an essential layer of protection in homes dealing with foundation wall leaks in Arlington’s rainy climate.
To move all collected water out of the home efficiently, we installed the TripleSafe sump pump system. With three layers of protection—including a secondary pump for high-volume situations and a battery backup for power outages—this system ensures water is removed even during the heaviest storms or emergencies.
We also installed the IceGuard discharge line protection system, which allows water to escape even if the pipes outside freeze during winter. This prevents dangerous backups and keeps the system functioning year-round.
With this multi-layered waterproofing system, the Arlington basement was completely transformed. From the alley door to the window wells and foundation walls, every potential point of water entry was addressed with high-performance, permanent solutions. The homeowner now enjoys a dry, clean, and usable basement, free from musty odors, moisture, or flood risk.
