Zavza Seal LLC was contracted to resolve a persistent groundwater issue at a property in New Suffolk, NY. The client reported excessive moisture accumulation under the on-floor slab on grade, particularly near the rear entrance of the building. This issue threatened the structural integrity of the slab and created potential water damage concerns.
Challenges
- Continuous groundwater accumulation beneath the slab.
- Risk of water infiltration at the rear entrance.
- Need for an effective drainage solution that integrates with the existing drywell system.
Our Solution
To address the issue, Zavza Seal LLC implemented a groundwater drainage system tailored to the property’s needs. The key steps included:
✅ Excavation & Drainage Installation
- A trench was excavated at the rear of the building, adjacent to the door.
- A 4-inch PVC pipe was installed on a gravel bed, creating a transition path for water flow towards the existing drywell.
✅ Filtration System to Prevent Clogging
- A filter fabric was installed over the gravel at the pipe opening to prevent sediment and debris from obstructing water flow.
✅ Sealing & Surface Restoration
- The PVC pipe was covered with gravel and topped with 4 inches of concrete for stability.
- The existing gravel driveway surface was swept back to cover the area, restoring the property’s original aesthetics.
