The Problem

A homeowner in Hicksville contacted Zavza Seal after noticing moisture coming through a crack in their basement foundation wall. The crack was about 7 linear feet long and had started to show signs of water seepage.

At first, the issue seemed minor. But over time, the homeowner noticed dampness around the crack and slight white residue on the surface, which is a sign of moisture moving through concrete. This is often called efflorescence and it usually means water is entering from the outside.

If not repaired, a foundation crack like this can lead to:

• Ongoing water intrusion
• Mold growth
• Damage to walls and flooring
• Weakening of the foundation over time

The homeowner wanted a proper fix that would stop the problem for good.

The Solution

Our team at Zavza Seal

created a simple and effective repair plan focused on sealing the crack and preventing future moisture entry.

We started by preparing the surface around the crack. Each side of the affected area was carefully ground to remove loose material, dirt, and efflorescence. This step exposed the original concrete and created a clean surface for the waterproofing system to bond properly.

Once the surface was ready, we applied the first layer of Basecrete Waterproofing Cement directly over the crack. This layer begins the sealing process and helps block moisture.

Next, we installed a reinforced 4.5 oz fiberglass mesh over the treated area. This mesh adds strength and flexibility, helping the repair handle small movements in the foundation without cracking again.

After that, we applied a second layer of Basecrete waterproofing cement over the mesh to fully seal the area. This final layer creates a durable waterproof barrier that protects the foundation from water intrusion.

The Result

After the repair was completed, the crack was fully sealed and protected. The basement stayed dry, and there were no signs of moisture returning.

The homeowner now has peace of mind knowing the issue was fixed the right way. The repair not only stopped the current leak but also helped prevent future problems.

Why This Repair Worked

Foundation cracks are one of the most common ways water enters a basement. This repair worked because it focused on proper surface preparation and used a reinforced waterproofing system.

By grinding the surface, applying Basecrete, and adding fiberglass mesh, we created a strong seal that can handle both water pressure and small structural movement.
