How We Protected a Flooded Basement from Heavy Storms with Expert Waterproofing Solutions - Wingdale, NY

Before	After

Last season brought a series of heavy storms that left many homeowners dealing with unexpected challenges. For one family, the relentless rain led to water seeping into their basement, creating pools of water along the foundation walls. Not only was their storage space compromised, but there were also concerns about long-term damage to the foundation and potential mold growth. They reached out to us, looking for a solution to keep their basement dry, prevent future flooding, and regain peace of mind.

After our initial inspection, we identified the critical areas of concern. The water infiltration was particularly severe near where egress windows were to be installed, and the existing drainage was insufficient to handle the heavy runoff. We put together a comprehensive plan to address these issues, focusing on both exterior and interior waterproofing solutions.

Our Approach to Fixing the Issue

Exterior Waterproofing Full Wall Height: We began by excavating the side of the foundation near the planned egress windows. Digging down to the footing, we installed a new footing drain system surrounded by clean stone to direct water away from the foundation. Next, we applied a GMX waterproofing membrane to seal the foundation wall and installed a drain mat over the membrane for added protection. This layer effectively channels any moisture down to the new drain system. After completing the waterproofing, we backfilled the area, leaving it at a rough grade. While we don't handle final lawn repairs, this step ensured the foundation was secure and ready for the next phase.

Gravity Line with Exterior Dig Up: To further enhance the drainage around the property, we installed a gravity line that would channel water away from the home. This line, installed in the exterior dig, provided an effective pathway for water to escape, reducing pressure on the foundation and keeping the basement dry.

FlowGuard Sub-Floor Drainage System: Inside the basement, we installed our FlowGuard sub-floor drainage system. This system captures any water seeping through the basement floor or walls and redirects it to the sump pump system, keeping the interior dry and preventing standing water.

Dual Pump Air-Tight Liner System: For reliable water removal, we installed a dual pump system with an air-tight liner. This included a 1/3 HP Zoeller pump and a backup 1/2 HP Zoeller pump for added security. The pumps, installed with clean pump stands, work together to handle heavy water flow and ensure continuous operation during extreme weather. We included a 25-foot discharge line to direct water away from the home’s foundation, along with IceGuards to prevent freezing during colder months. The homeowners were responsible for arranging the electric hook-up to power the system.

SunHouse Basement Window Enclosures: We also installed a SunHouse window enclosure with a cover to protect the new egress window area from rain and debris. While the enclosure alone doesn't prevent window leakage, it creates a barrier that reduces the amount of water reaching the window.

Egress Stackwell Installation: Finally, we installed a new Egress Stackwell to allow for a safe exit from the basement while providing a clean and protected space for the new window. This addition not only improved safety but also enhanced the overall appearance of the exterior space.

After implementing these solutions, the homeowners could rest easy knowing their basement was well-protected against future storms. The combination of exterior waterproofing, drainage systems, and a dual-pump solution ensured that water was directed away from the home and properly managed, even in the heaviest downpours. They now have a dry, usable space that can safely weather whatever nature brings next. The family is thrilled with the results, and we’re glad to have provided a lasting solution to their water woes.
