Problem
The homeowner in Hicksville, NY contacted Zavza Seal with multiple concerns related to water intrusion and visible foundation issues. The property exhibited one structural foundation crack that posed a risk to the basement’s structural integrity and waterproofing.
Additionally, water infiltration was occurring along the east and south-facing exterior foundation walls. Poor grading around the foundation was allowing rainwater to collect and seep into the structure. Inside the basement, water intrusion was also observed at the floor joint where the slab meets the foundation wall, signaling a breakdown in the moisture barrier.
Lastly, the window wells were in deteriorated condition. They lacked proper drainage and secure covers, allowing debris and rainwater to accumulate dangerously close to the foundation.
These issues posed serious risks to the home’s foundation, indoor air quality, and long-term durability. The homeowner needed an experienced and reliable foundation waterproofing contractor in Hicksville to address these concerns thoroughly and effectively.
Solution
Our team at Zavza Seal designed a phased and structured repair approach to address each of the critical areas of concern using high-performance materials and proven techniques.
Subject Area 1: Structural Foundation Crack
- We began by applying a 7,000 PSI breathable waterproofing cement over the existing foundation crack to create a durable moisture barrier.
- Over the waterproofing layer, we installed Basecrete brand 4.5oz reinforced Fibermesh, a flexible fiber-reinforced material designed to add structural reinforcement.
- To finish, we applied a final coat of 7,500 PSI breathable waterproofing cement to provide superior surface protection and long-term durability against future water intrusion or crack development.
This process strengthened the wall, stopped existing leaks, and helped restore structural stability.
Subject Area 2: Exterior Foundation Walls (East Wall and South Wall to Deck)
- Our team delivered and spread 2 cubic yards of soil to cover the base of the east and south foundation walls.
- We regraded the soil to divert water flow away from the foundation, preventing pooling and hydrostatic pressure against the wall.
- Using a commercial-grade tamper, we compacted the soil to reduce settlement and maintain positive drainage over time.
This grading correction addressed one of the core contributors to water infiltration and helped prevent future basement flooding.
Subject Area 3: Interior Waterproofing for Floor and Foundation Wall Joint (Approx. 52 Linear Feet)
This was the most technically complex area, requiring a multi-layered approach to fully stop water from entering at the floor and wall intersection.
- We ground the joint between the foundation wall and floor slab using a diamond blade and steel brush to ensure full adhesion for subsequent treatments.
- On the cleaned and prepped surface, we applied Intercept, a high-performance concrete densifier. This penetrates deep into the concrete’s molecular structure, bonding with free calcium and lime to form a colloidal silica gel barrier.
- Intercept was left to cure for a full day, with floor fans running continuously to ensure optimal performance.
- Once cured, we applied a layer of 7,000 PSI breathable waterproofing cement directly over the densified surface. This created a reinforced, vapor-resistant barrier along the entire joint.
- We installed Basecrete 4.5oz Fibermesh at the wall and floor joint to provide additional tensile strength.
- To finish the process, we added a final topcoat of 7,500 PSI waterproofing cement, increasing the durability and allowing us to extend a 30-year warranty on the repaired section.
This thorough approach addressed water infiltration at its most vulnerable point, improved foundation longevity, and added measurable value to the home.
Subject Area 4: Window Wells
The existing window wells were failing and posed a drainage and safety hazard.
- We removed and disposed of the existing window guards.
- Our team excavated the window wells to a depth of 4 feet, providing adequate space for proper drainage.
- We installed a 6-inch gravel bed to support the drainage system and prevent soil displacement.
- A self-contained drainage system was embedded in the gravel, topped with a protective grill to prevent blockages.
- We installed new galvanized window guards to ensure safety, security, and durability.
- Each well was then completed with a new plastic window well cover, protecting the area from rain, leaves, and snow accumulation.
This updated system significantly reduced the risk of water pooling near basement windows and created a cleaner, safer environment.
