Job Stories From Prince William County, VA
WaterGuard Installation in Occoquan, VA

Elaine M. was having water problems in her finished basement. We proposed installing our WaterGuard system along with a SuperSump and subsequent discharge line, fitted with IceGuard to fully protect the home. This would eliminate any chance water would plague the basement in the future. 

Push Piering in Woodbridge, VA

This home in Woodbridge was experiencing symptoms of potential foundation settlement. The homeowners noticed several fairly large cracks in their foundation walls and cracks scattered across the basement. They wanted to have someone assess the situation and tell them definitively whether it was a foundation issue. One of our technical advisers, Jaime Baires, went out to confirm and found that the entire left side of the home was sinking. He proposed installing push piers along the front and side of the home to permanently fix this settlement. The installation went great and the homeowners no longer have to worry about their foundation posing problems for their home!

PowerBrace Wall Support in Dumfries, VA

Luke W. of Dumfries, VA was experiencing walls that were starting to bow inwards in his basement, along with some water intrusion in one corner. He called NV Waterproofing to provide a potential solution for these issues, so Greg Keoho went out to provide an estimate. He proposed the addition of 7 PowerBraces and exterior waterproofing on the front of the house and in the corner where the water was observed to be entering the basement. The attached photo shows where the water was entering the basement. 

The PowerBrace System consists of steel I-beams that anchor to the joists above the wall with steel brackets. It is easily adjustable, which allows it to be tightened over time to raise the wall back to its original position. What is unique about the PowerBrace system is that it involves no exterior excavation and installs quickly with minimal disruption to your basement. 

With the addition of the PowerBraces and the exterior waterproofing, Luke. W.'s basement walls would be stabilized and any future water intrusion issues would be mitigated.

Waterproofing of Local Church in Nokesville, VA

The Greenwich Presbyterian Church was experiencing some water issues in various places in the basement, which was home to numerous classrooms and areas where the youth group met. Greg Keoho went out to provide them with a solution to solve the problem for good. We installed CleanSpace the full height of the walls, paired with WaterGuard, and a new TripleSafe sump pump. We also added 20 ft of exterior discharge line, TrenchDrain, and IceGuard to make absolutely sure that the basement of the church would be permanently protected from any future water damage. 

A Cracked Foundation Wall in Woodbridge, VA

Andrew from Woodbridge, VA called NV Waterproofing after finding us during an internet search. Jaime, our project design specialist, went out to Andrew's home to provide him with a free on-site estimate for Foundation Repair. He had horizontal and stair-step cracking in his foundation wall. After agreeing to the proposal he received, Andrew hired us to install our CarbonArmor Wall Reinforcing System. This will stabilize the wall and did not require any external excavation. 

Stair-Step Cracks in a Foundation Wall in Dumfries VA

Charles from Dumfries VA called NV Waterproofing after searching on the internet for a local foundation repair company. He was noticing that two of his foundation walls in his basement had stair-step cracks and were starting to bow inward. This had Charles very concerned for his safety and for the structure of his home.

After listening to Charles concerns, we set up an appointment for a free on-site estimate. We sent one of our top system design specialists, Kevin, out to his home to give him a quote for the repairs. Kevin instantly knew exactly what was needed to solve the foundation issues. 

Charles wound up needing 13 of our Power Braces installed in his basement. Our PowerBrace Foundation Wall Repair System stabilized his walls, preventing any further damage to occur. Since they are adjustable, our installation team was able to bring the walls back to their original position, and no exterior excavation was needed. 

A Chimney That is Seperating from a Home in Nokesville VA

Ken from Nokesville VA gave NV Waterproofing a call after finding us during an internet search. He was noticing that his brick chimney was starting to pull away from his home and that had him very concerned. 

After listening to Ken's concerns, we set up an appointment for him to receive one of our free on-site estimates. Greg, one of our top foundation specialists, went out to his home, and determined that  Ken needed to have our Helical Piers installed to stabilize his chimney.

Our installation team installed two of the Helical Piers, which not only stabilized his chimney, but they also lifted the it back up to its original position. This put Kens mind at ease.
