Job Stories From Ashburn, VA
Installation of Trench Drain and Flo Well

The homeowner, who had been facing the recurring issue of water entering their garage, reached out to NV Waterproofing for a solution. 


After carefully examining the source of the water infiltration, the team recommended the installation of a flo well and a trench drain as an effective solution. The flo well,  will efficiently manage the standing water, preventing any further damage or inconvenience caused by the water accumulation. In addition, a trench drain was strategically placed in front of the garage entryway to divert excess water away from the area, ensuring a dry and safe entrance.


Aware of the importance of preventative measures, Oswaldo's crew also took the initiative to clean out the gutters. This proactive step would prevent future water-related issues by allowing smooth water flow and preventing any blockages that could lead to overflow and subsequent damage.


Once the installation was complete, the homeowner expressed immense satisfaction with the work done by the crew. They were relieved to see their garage protected from water intrusion, and they appreciated the professionalism and efficiency displayed throughout the process.

Rear corner of Townhome basement leaks water during heavy rain. I have cleaned gutters, checked grade, installed a DIY drainage system in the back yard - all in 2021 when the issue was first noticed. That alleviated the issue until a week ago when it happened again. Removing the drywall it appears the water originates from under the wall base board in contact with the foundation. Above the board is dry. Water recedes when the heavy rain ends and is dry in a few hours. Pictures show with the drywall removed and the most recent incident. Looking for some help.

Bought our house over a year ago. We have noticed some floor cracking. It could be time to replace the flooring but we just want to check the foundation to be sure.

Hi, we are interested in having a company come out and check some cracks we are seeing in our home to see if it may be foundation related. There are a couple of places we have seen cracks and they are along the seams of where 2 perpendicular walls come together. We don't really see any other concerning signs but wanted to see if we need to budget for a fix. Jimmy
