Flash Flooding issues in Alexandria, VA

A property owner in Alexandria that is frequently plagued by flooding issues on the ground floor (sans basement) due to flash floods. Despite having a sump pump and drain system in place, recent flooding has caused some damage, prompting them to seek additional remedies and solutions. the homeowner reached out to NV Waterproofing to assess the situation and propose further measures, taking advantage of the current state of open walls.

Following a comprehensive inspection by our team of technical experts,

The recommended solution involves the installation of a Trench Drain equipped with Trenchlock, a Triple Safe sump pump featuring two supplementary backup systems, and a Water Watch alarm system for optimal protection.

The client had the intention of converting their basement into an Airbnb. However, an inspection revealed water intrusion through the basement walls, which could potentially disrupt their plans. To resolve this issue, we suggested waterproofing the basement from the outside, thus enabling them to proceed with their Airbnb project.

After securing the required permits, our team embarked on the task. They excavated around the property to expose the foundation. The next step involved clearing all dirt and debris from the walls and applying a liquid rubber sealant. They installed a drain board as well as a French drain surrounded by gravel and wrapped in filter fabric.

To provide an extra layer of protection and ensure the basement remains dry under all circumstances, we also installed a triple safe sump pump. Our electrician was brought in to install a lawnscape outlet, which is essential for running the sump pump. We also took the initiative to seal any visible cracks on the foundation.

The final stage involved a thorough cleanup, leaving no trace of the extensive work that had been carried out. This attention to detail resulted in another satisfied customer.

Crawl Space Supported with New Supplemental Beam and Joists in Alexandria

A homeowner in Alexandria, VA, became concerned about the home's crawl space foundation after reading an inspector's report.

 

The home, that was built in 1959, was recently purchased. The buyer wanted to make sure the structure would last with a permanent solution.

 

The crawl space had wooden beams exposed to the elements. This could lead to sagging floors, separating floorboards and other issues inside the home.

 

The homeowner trusted NV Waterproofing to inspect his crawl space foundation. The design specialist educated the homeowners on the reasons why they were seeing the issues outlined in the inspectors report. The homeowner agreed it would be best to replace the joists in the space and add a steel supplemental beam to reinforce the structure.

 

NV Waterproofing installation crews stabilized the crawl space by installing the beams and then sealed out any future trouble by adding a vapor barrier.
