Project Overview
This project started with what appeared to be a patio problem, but after a full inspection, our team discovered several issues affecting the property. The backyard patio had been built on an improper base, there were signs of water intrusion throughout the basement, mold growth was present in several areas, and the drainage system was not performing properly.
The homeowner wanted a long-term solution rather than temporary repairs. Our team developed a plan to address the moisture problems, improve drainage, eliminate mold, reinforce structural components, and rebuild the patio foundation correctly.
The Problem
The biggest concern outside was the back patio. The tiles had been installed over a layer of sand covered with thinset mortar. While thinset is commonly used for tile installation, the sand underneath did not provide a stable foundation. Over time, this type of installation can shift, settle, and lead to cracked or loose tiles.
Inside the home, the basement showed signs of ongoing moisture problems. Water was finding its way into the basement, creating conditions that allowed mold to grow. The homeowner was also concerned about air quality and the possibility of future water damage.
Our inspection found that the property’s drainage systems were not effectively moving water away from the foundation. The dry wells required cleaning and improvements, and additional measures were needed to protect the basement from groundwater intrusion.
We also identified areas around an existing steel beam that would benefit from reinforcement to improve long-term structural stability.
Our Solution
To correct the patio issue, we removed the existing thinset and sand base until we reached the concrete substrate below. Once the area was properly prepared, we applied a bonding agent and installed a new reinforced concrete foundation using 4,000 PSI high-strength concrete. This created the solid base needed for a durable patio system.
Inside the basement, we performed a complete mold remediation process. All affected surfaces were cleaned, sanitized, and treated with a professional-grade disinfectant. After the cleaning process was complete, we applied a protective coating designed to help prevent future mold and fungal growth.
To improve air quality during the remediation process, we operated commercial-grade HEPA air scrubbers for several days. This helped remove airborne mold particles and created a cleaner environment throughout the basement.
Because moisture was one of the main causes of the problem, we also installed a new French drain system around the basement perimeter. This system collects groundwater before it can enter the living space and directs it toward a newly installed sump pump system.
For additional protection, we installed a duplex sump pump setup. The system includes two pumps, allowing one pump to serve as a backup if the primary pump becomes overwhelmed during heavy rain or high groundwater conditions.
Outside the home, we cleaned and upgraded three existing dry wells to improve drainage performance. We also installed additional drainage components designed to move water away from the foundation and reduce pressure against the basement walls.
To strengthen structural support in key areas, we reinforced the steel beam connections using high-strength grout and construction-grade adhesive materials.
The Result
After the project was completed, the property had a much stronger defense against water intrusion and moisture-related damage.
The patio now sits on a properly reinforced concrete foundation designed for long-term durability. The basement is protected by a perimeter drainage system and a reliable sump pump setup. Mold contamination was removed, indoor air quality was improved, and drainage around the property was upgraded to better manage stormwater and groundwater.
Most importantly, the homeowner gained peace of mind knowing that the root causes of the moisture issues had been addressed rather than simply covering up the symptoms.
Why This Project Matters?
Many homeowners only notice the visible signs of a problem, such as mold, damp walls, or shifting patio tiles. In reality, these issues are often caused by poor drainage and water intrusion that has been developing for years.
By addressing the drainage, waterproofing, mold, and structural concerns together, this project provided a complete solution that helps protect the home from future damage while creating a healthier and more durable living environment.
