Local Basement Waterproofing Experts in Brooklyn

Our team at Zavza Seal recently completed a basement waterproofing project in Brooklyn, NY. The homeowner contacted us after noticing moisture stains, white powder on the walls, and a damp smell coming from the basement.

This project focused on waterproofing approximately 35 linear feet of cinder block foundation wall at a height of 6 feet.

The Problem:

The homeowner was dealing with ongoing water penetration through the cinder block foundation walls. The main issues were:

• Peeling paint on basement walls
  
• Efflorescence, which is a white chalky powder caused by water movement
  
• Mildew growth
  
• Damp air and musty odor
  
• Risk of long term structural damage

Cinder block walls are porous. When left untreated, they absorb water from the surrounding soil. Over time, this leads to cracks, mold growth, and weakening of the wall structure.

According to the International Association of Certified Home Inspectors, moisture intrusion in basements can lead to structural damage and unhealthy indoor air conditions. The homeowner needed a long term solution, not just a quick patch.

Our Solution:

At Zavza Seal, we follow a step by step process to ensure the wall is fully prepared and properly sealed.

Step 1: Surface Preparation

We scarified the entire cinder block wall area, about 35 linear feet wide and 6 feet high.

• We used chisels to remove all foreign materials
  
• We removed paint, efflorescence, and mildew
  
• We exposed clean and solid masonry
  

Proper preparation is critical. Waterproofing products will not bond correctly if the surface is dirty or weak.

Step 2: Hydraulic Cement Application

After preparing the surface:

• We applied hydraulic cement where needed
  
• This sealed active gaps and minor cracks
  
• Fans were left running to help speed up the curing process
  

Hydraulic cement expands as it cures, which helps block water intrusion at problem areas.

Step 3: Base Coat Application

On the prepared surface:

• We applied a coat of Basecrete Intercept
  
• This created a bonding and waterproof base layer
  

This step strengthens adhesion and improves overall performance of the waterproofing system.

Step 4: Waterproofing Cement and Mesh Reinforcement

To complete the system:

• We applied a coat of Basecrete waterproofing cement
  
• We embedded fiberglass mesh into the first layer
  
• We finished with a second layer of Basecrete waterproofing cement
  

The fiberglass mesh reinforces the coating and helps prevent future cracking. The final result is a strong, sealed, and water resistant barrier.

The Result:

After completion:

• The walls were fully sealed
  
• The damp smell was eliminated
  
• The basement felt noticeably drier
  
• The homeowner gained peace of mind
  

This Brooklyn basement is now protected against moisture intrusion and future water damage.
