Crawlspace support and encapsulation in Lincoln, VA
Challenge
The customer found themselves confronting a worrisome issue in their home: bowing and sagging floors. This problem, which is not only aesthetically displeasing but can also be potentially dangerous, had become a significant cause of concern for them. To address this, our team of Technical Advisors and Design Specialists visited the property to assess the situation.
Upon inspection, they identified two root causes: poor support in the crawlspace and damp conditions within the same area. These problems, often overlooked, were silently causing structural damage to the residence. The challenge was not just recognizing these issues, but also figuring out the best way to rectify them while ensuring the safety and longevity of the home.
Solution
In order to address the issue of bowing and sagging floors, we proposed a comprehensive solution.
The first step was the installation of the CleanSpace high-performance moisture and vapor barrier. This would be mechanically fastened to the walls and connected to the Radon Mitigation System. Following this, the CleanSpace Drainage Matting was installed under the liner for additional protection.
Next, we installed the SilverGlo high-performance graphite insulation as indicated on the job drawing, followed by the EverLast Door. We also covered the vents with vent covers and placed a SilverGlo Block inside each vent.
The team then removed the debris from the area before installing the Smart Drain sump liner with an alarm. This would allow surface water to drain below the CleanSpace Liner while sounding an audible alarm if water levels got too high.
To further stabilize the structure, we installed the SmartJack support system to the floor joist or beams as shown in our plans. A supplemental beam, as indicated on the job drawing, was also put in place. Additionally, we added support to the existing structure by sistering the floor joist.
To improve air quality and control humidity, we installed the SaniDry Sedona high-performance dehumidification and air purification system.
We took care of all necessary mobilization, permit fees, and engineering services. This included the installation of a 1/3 hp cast iron pump in a TripleSafe liner with a clean pump stand, and an IceGuard to prevent floods from clogged or frozen discharge lines.
The exterior discharge line was installed as shown on the drawing, ending with a LawnScape outlet.
To ensure all systems were powered correctly, we installed a new dedicated outlet for the sump pump, subject to panel capacity. This did not include any needed upgrade to accommodate a new circuit. An electrical permit was pulled for the work.
Finally, we installed two new dedicated outlets for the sump pumps inside the basement, again subject to panel capacity and not including any needed upgrades or permits.
Through these comprehensive measures, we aimed to rectify the existing structural issues and prevent future ones, ensuring the longevity and safety of the home.
