Problem
A homeowner in East Hampton, NY contacted Zavza Seal regarding persistent water intrusion in the basement, particularly in the area where the waste line passes through the foundation wall. This joint, which penetrates the exterior foundation, had deteriorated over time, allowing water to seep through during rain events or periods of high groundwater saturation.
The water intrusion not only threatened the structural integrity of the foundation but also increased the risk of mold growth and damage to interior finishes. In addition, the property lacked a reliable water management system inside the basement, leaving the space vulnerable during storms or power outages.
The client sought an expert foundation waterproofing contractor in East Hampton who could identify the root cause of the leak, repair the issue at both the exterior and interior levels, and provide a dependable drainage solution.
Solution
Our team designed a comprehensive, three-part solution to address both the source of the water intrusion and the basement’s vulnerability to future flooding. The repairs were performed with a focus on long-term durability and ease of system monitoring.
Item 1: Exterior Foundation Wall Joint Sealing
- We began by cleaning the exterior joint around the waste line where it penetrates the foundation wall. All loose material and deteriorated sealants were removed to ensure a clean bonding surface.
- Once the joint was properly cleaned, we applied high-grade waterproofing sealants and a layer of waterproofing cement to seal the gap between the waste line and the concrete foundation wall.
- This targeted repair stopped water from entering through the joint and formed the first line of defense against future leaks.
Item 2: Emergency Combo Sump Pump Installation
To protect the basement interior and manage any groundwater buildup, we installed a combo emergency sump pump system at the inside corner of the basement foundation wall, as per the specifications in drawing SK-1.
- The system includes a 1/2 HP primary sump pump, capable of pumping 4,320 gallons per hour, which handles regular drainage needs.
- As backup, we installed a 12-volt battery-operated pump, which kicks in during power outages and can pump 3,600 gallons per hour, ensuring continued protection during storms.
- The sump pump system is WiFi-connected and remotely monitored, providing the homeowner with real-time alerts and activity logs.
- This installation greatly improved the basement’s ability to handle sudden water entry and added peace of mind through smart monitoring technology.
Item 3: Excavation and Full Exterior Joint Waterproofing
To reinforce the waterproofing of the waste line joint from the outside, we conducted a controlled excavation.
- We excavated the exterior of the foundation wall to expose the full length of the waste line joint.
- After gaining access, we once again cleaned the area thoroughly and applied advanced waterproofing materials to ensure a watertight seal.
- Over the repaired section, we installed a durable protection mat, adding a secondary barrier against shifting soil and groundwater pressure.
- We then backfilled the excavated area with clean soil and compacted it to restore the grade level, promoting proper surface drainage away from the foundation.
