Project Overview
Our team at Zavza Seal completed a full basement waterproofing and structural repair project. The home had water intrusion, drainage problems, and weak support columns. The goal was to stop water from entering, improve drainage, and make the structure safe and strong again.
The Problem
The homeowner was dealing with multiple issues at the same time.
Water was coming in through the foundation joints around the basement. This is a common problem when old surfaces crack or lose their seal.
Outside, the foundation wall was not properly protected, allowing water to sit against it. This increases the chance of leaks.
Two windows were also causing problems. One needed better drainage around it, and the other was allowing water to enter.
There were also signs of moisture around the chimney area, which can lead to leaks if not sealed properly.
Inside the basement, four wooden support posts were damaged. They had cracks and splitting, which is dangerous because they carry heavy weight from the home above.
In the backyard, the sump pump discharge was not working correctly. Water was not being directed away from the house, which made the problem worse.
The Solution
We created a complete plan to fix each issue step by step.
For the foundation joints inside the basement, we ground the surface to reach a clean base. Then we applied a strong waterproofing system using Basecrete cement. We added fiberglass mesh between layers to make it stronger and long lasting. The waterproofing was extended two feet up the wall for better protection.
On the exterior foundation wall, we excavated about three feet down along 22 feet of the wall. After cleaning the surface, we applied a liquid waterproof membrane. We finished by installing a sloped membrane that directs water away from the foundation.
For the windows, we installed a new window well to improve drainage and adjust the soil slope. The second window was sealed permanently using cinder blocks and waterproof cement to stop water from entering.
Around the chimney, we sealed all joints where water could enter. This helps prevent leaks and keeps the structure dry.
For the basement support, we removed the four damaged wooden posts. Before removal, we added temporary support to keep the structure safe. We then broke open the slab and created new concrete footings with rebar for strength. After the concrete cured, we installed new steel columns and secured them in place.
In the backyard, we fixed the sump pump discharge system. We dug a trench about 55 feet long and installed a new 4 inch PVC pipe. This pipe now directs water to the sewer trap. We tested the system using a drain snake to make sure everything flows properly.
The Result
After the project, the basement is now dry and protected. Water is no longer entering through the foundation or windows.
The new drainage system moves water away from the home, which reduces pressure on the foundation.
The steel columns provide strong and reliable support, making the structure safe again.
Overall, the home is now protected from water damage and has a solid structural base.
Why This Matters
Waterproofing and structural repairs are very important for any home. Small leaks can turn into major damage if ignored. Weak supports can also lead to serious safety risks.
Guidelines from the International Code Council highlight the importance of proper structural support and moisture control in homes.
