NV Waterproofing & Foundation Repair serving Ashton, MD

The homeowner discovered mold and damp walls in their basement, prompting them to remove all finished parts of the basement to address the water intrusion issues. Our team of technical advisors conducted a thorough inspection of the basement and recommended a comprehensive interior and exterior waterproofing system.

The recommended measures include:

• Installation of the WaterGuard sub-floor drainage system
• Installing a Pop up Emitter and WellDuct on the window well 
• Placing a perforated corrugated pipe under the slab to collect water and direct it to the sump pump.
• Incorporating an IceGuard system to prevent floods from clogged or frozen discharge lines.
• Establishing an exterior discharge line
• Installing the TripleSafe pump system, equipped with a twin liner, 1/3 hp cast iron primary AC pump, 1/2 hp cast iron AC back-up pump, and UltraSump battery back-up pumping system with charging/control box with alarm, and 120 amp sealed maintenance-free battery. This also includes 3 CleanPump stands, an airtight lid with airtight floor drain, and a WaterWatch alarm system.
• Applying IceGuard to prevent floods from clogged or frozen discharge lines.
• Implementing the CleanSpace Wall System on the walls
• Installing the SaniDry Sedona high-performance dehumidification and air purification system, with both supply and return air ducted to the SaniDry Sedona system.
• Utilizing Mold-X 
• Installing an exterior discharge line 
• Implementing an Exterior Pump System, including the Flu Line. This involves primarily or wholly digging with equipment, excavating a trench to expose the foundation wall from grade level to the base of the footer. Any dirt and debris on the wall will be removed, and the wall will be thoroughly cleaned. Cracks, seams, holes, and imperfections in the foundation wall will be sealed, followed by the application of liquid rubberized waterproofing sealant to subgrade walls. A semi-rigid drain board will be installed on treated walls, secured with a termination bar, and sealed with caulking material. A French drain system embedded in gravel, enclosed by filter fabric, will be installed, draining to a sump pump or directly to the exterior area of the house. Finally, the excavated area will be backfilled, graded, and tamped.
