Before Crawl Space Repair:
Standing Water in the Crawl Space
During our inspection of the medical clinic, we identified standing water throughout the crawl space. This moisture buildup was primarily due to poor drainage and a lack of waterproofing systems. With each rainfall, pooling surface water from overflowing gutters and sloped soil found its way into the crawl space.
Humidity and Air Quality Concerns
High humidity levels in the crawl space created ideal conditions for mold to thrive.
Without any protective covering over the soil, moisture was able to rise freely, impacting the air quality inside the clinic above. This not only risked structural damage but also posed serious health risks for patients and staff.
Worsening Conditions from Rainfall
High humidity levels in the crawl space created ideal conditions for mold to thrive.
Without any protective covering over the soil, moisture was able to rise freely, impacting the air quality inside the clinic above. This not only risked structural damage but also posed serious health risks for patients and staff.
After Crawl Space Repair:
CrawlDrain™ System and Matting
To tackle standing water, our team installed a CrawlDrain™ system along with drainage matting. These components work together to collect and redirect water away from the crawl space, helping to keep the area dry even during heavy rainfall.
Sump Pump with Battery Backup
We placed a sump pump in the lowest point of the crawl space to effectively remove water collected by the drainage system.
The added battery backup ensures that the sump pump continues working even during power outages, offering year-round protection.
Exterior Discharge Line
An exterior discharge line was connected to the sump pump system to carry water away from the building’s foundation.
This helps prevent water from pooling around the perimeter and re-entering the crawl space.
20-Mil Vapor Barrier Encapsulation
After waterproofing, we fully encapsulated the crawl space using a durable 20-mil vapor barrier.
This thick liner was sealed along the floor and walls to prevent moisture from rising through the ground or seeping through the foundation walls.
High-Capacity Dehumidifier
Finally, a high-performance dehumidifier was added to control humidity levels.
This unit helps improve air quality throughout the clinic and prevents mold growth, ensuring the crawl space remains dry and healthy long-term.

Overall Excellent Service!!! Andrew was very thorough in completing our annual service. When he finished, we went through all the details of how our crawl space looked. Andrew was very friendly, informative and was a good representative for Groundwork’s. On top of that the service was a third of the price from the past years. Highly recommended Groundworks
