Location:
Middle Village, NY
Client Concern:
A homeowner in Middle Village was facing persistent patio water accumulation issues, particularly near the base of their building. Water runoff had no proper outlet, creating pooling and increasing the risk of foundation moisture problems. The homeowner reached out to Zavza Seal for a long-term drainage solution that would protect their property while preserving the aesthetic of their existing patio.
The Problem
- Poor Drainage Design: The patio lacked an effective water discharge system, causing rainwater to accumulate dangerously close to the structure.
- Subsurface Complexity: Beneath the patio pavers was a concrete slab with mortar joints, making typical excavation challenging.
- Risk to Pavers: Due to the concrete beneath and around the pavers, any attempt to remove them for drain installation risked cracking or damaging the stones.
- Need for Connection to Existing Sewer Line: Any new drainage installation required a proper connection to the property’s existing sewer system for effective water redirection.
Zavza Seal’s Solution
Our team developed a customized drainage plan that prioritized both functionality and preservation of the existing patio structure. We recommended trench drain installation with minimal disruption to the current paver layout.
Step 1: Precise Saw Cutting for Drainage Channel
- Saw Cut and Excavation:
We saw cut a 12 to 14-inch wide strip through the pavers and underlying concrete slab, located approximately 5 to 6 linear feet from the building wall. - Drainage Access:
This approach allowed us to excavate efficiently and prepare for trench drain installation without damaging a large section of the patio.
Step 2: Trench Drain Installation and Sewer Connection
- Trench Drain Installation:
A trench drain was installed parallel to the wall to collect surface water effectively. - Sewer Line Connection:
We saw cut and excavated the area as needed to connect the new trench drain directly into the property’s existing sewer line, ensuring a complete and efficient water redirection system.
Step 3: Paver Preservation and Surface Finishing
- Paver Reintegration:
We carefully backfilled and filled the gap between the trench channel and the remaining pavers using a high-strength mortar mix matched to the existing stone for a seamless finish. - Preservation Tactics:
To avoid breaking the pavers unnecessarily due to their mortar-bound installation, we preserved as many intact pavers as possible and replaced others using a visually matched mortar expansion joint.
Step 4: Connecting Patio Water Discharge
- PVC Installation:
We saw cut the necessary areas of the patio to install a 4-inch PVC pipe for direct water discharge into the newly installed trench drain. - Final Touches:
Where paver preservation was not possible, we sealed the area using a mortar expansion joint that blended with the surrounding design, keeping the patio’s aesthetic intact.
Results and Benefits for the Homeowner
- Effective Water Management: Rainwater now flows safely into the trench drain and away from the home, significantly reducing moisture risk to the foundation.
