Job Stories From Alexandria, VA
Garage Foundation issues in Alexandria, VA

We had a client who was quite worried about some foundation cracks in their garage. So, we sent our technical advisor over to the property to take a look. After a thorough investigation, our advisor came up with a comprehensive solution to fix the foundation problem. Here's what we did: First, we installed push piers. These provided the much-needed support to the foundation and helped prevent further cracking. Secondly, we buried the downspouts. This step ensured that there was better drainage and less pressure on the foundation. Thirdly, we fitted a LawnScape outlet at the end of the discharge line. This addition effectively diverted water away from the foundation, preventing any potential water damage. Lastly, we repoured the concrete in the garage. This created a smooth, renewed surface free of cracks. With these steps, we were able to successfully address the foundation concerns our client had. We're proud to say that we delivered a comprehensive and effective solution to their foundation problem.

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.

We addressed the homeowner's concerns about recurrent flooding caused by flash floods in the area. To tackle the flooding on the main floor, we installed a reliable and effective solution called the Triple Safe Sump Pump. This sump pump is equipped with three backup systems, ensuring that even in the event of power loss or system failure, the water from the flooding will be efficiently pumped out. Additionally, we installed a trench drain on the exterior of the home to further mitigate the issue. The homeowner was extremely satisfied with the installation and the positive results achieved by the systems implemented.

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.

Basement Waterproofing and Wall Repair in Alexandria, VA

One Alexandria homeowner had been dealing with water seepage in his basement for years. He tried to stop the issue with waterproof paint, towels, and even a drainage system installed by a handyman. Nothing fixed the problem. He finally decided to have a pro come and take a look at the problem. When NV Waterproofing and Foundation Repair arrived, they properly assessed the issue with a thorough inspection. When the inspection was over, the technical advisor walked the customer through everything he found including some bowing walls. After hearing the risks of water seepage and bowing walls, this homeowner decided to have us fix the problem. Since having his system installed, he has not experienced a single drop of water and has had complete peace of mind that his foundation is secure.

Basement Peace of Mind in Alexandria, VA

This Alexandria, VA homeowner had plans to finish his basement. Unfortunately, those plans were delayed due to continued water intrusion in the basement. We proposed the installation of our WaterGuard sub-floor drainage system, a 1/3 hp TripleSafe sump pump, a new exterior drainage line complete with IceGuard to prevent clogging, and CleanSpace vapor barrier to permanently fix his water issues.
