Problem

A homeowner in Patchogue was dealing with ongoing water seepage around the basement walls and poor drainage from roof downspouts. During heavy rain, water would collect around the foundation and slowly make its way into the basement. The walls showed clear signs of moisture, including staining and early mold growth.

The outside of the home also had drainage issues. The roof downspouts were releasing water too close to the foundation, which increased pressure on the basement walls. The yard did not have a proper underground drainage system, so water had nowhere to go.

In addition to the water problem, the property needed structural improvements. The homeowner wanted a new patio and walkway, a stable base for an AC unit, and better protection around basement windows. The goal was not just to fix the current issue but to create a long-term solution that would prevent future damage.

Solution

The team at Zavza Seal created a complete waterproofing and drainage plan to solve the problem from both inside and outside. The focus was to control water at the source and protect the foundation.

We started by installing an underground drainage system connected to the existing roof downspouts. Trenches were carefully cut into the ground to a depth of about 24 inches. Inside these trenches, we installed solid 4-inch PVC pipes on a compacted gravel base. These pipes were directed into a dry well located in the lawn area. This system now safely redirects water away from the foundation, reducing pressure on the basement walls.

To support the new patio area, we prepared the ground by backfilling and compacting the soil to ensure long-term stability. We then installed a strong concrete patio measuring 13 feet 6 inches by 18 feet, along with a 36-inch-wide walkway leading to the side entrance. The base included 5 inches of compacted gravel and a 5-inch-thick reinforced concrete slab with a broom finish for durability and slip resistance.

We also installed a new concrete pad for the AC unit to provide a stable and level surface. This helps protect the equipment and ensures proper performance over time.

Inside the basement, we addressed the main cause of water seepage by waterproofing the foundation walls. The wall surface was first ground down using a diamond blade to remove paint, mold, and efflorescence. This step exposed clean concrete, which is necessary for strong adhesion.

We then treated the wall and floor joint by grinding both vertically and horizontally to create a clean bonding area. A reinforced waterproofing system using Basecrete was applied along with fiberglass mesh. This created a strong barrier that prevents water from entering through the foundation. The entire area was cleaned and sealed carefully to ensure long-lasting results.

To improve protection further, we installed three new polycarbonate window well liners with fresh gravel. We also added a self-contained drainage system in this area to prevent water buildup near the windows.

Result

After the project was completed, the home was fully protected from water intrusion. The new underground drainage system now moves water safely away from the property. The basement walls are sealed and protected, reducing the risk of mold and structural damage.

The new patio, walkway, and AC pad improved both the function and appearance of the home. Most importantly, the homeowner now has peace of mind knowing their basement is dry and protected for the long term.

This project shows how a complete waterproofing and drainage approach can solve both visible and hidden water problems. By addressing the root cause and not just the symptoms, Zavza Seal delivered a reliable and lasting solution.
