Job Stories From Gretna, NE
Buckling Basement Walls Saved By Geo-Lock

Paulette of Gretna, NE was worried about a wall in her basement that she noticed was leaning and buckling. She knew that walls that leaned were often the result of poor foundations and could lead to further damage to the house. Seeking professional help, she decided to call Thrasher.

After she learned her options, Thrasher installed five Geo-Lock wall anchors to the walls. The project only took one day to install. This ensured that Paulette would no longer have to be concerned about her walls sinking due to poor foundations and structures. 

Impediment To Basement Remodeling Resolved

Vernon and June of Gretna, NE wanted to remodel their basement so that it was easier to walk though. But there were a couple complications to their initial plans. They needed a way for their sump pump to pump the water out of the house efficiently and away from the foundations of the house. They called Thrasher to work out a solution.

Thrasher installed a buried discharge and an IceGuard system ten feet from the corner of their house. This allowed water to flow out of the house and then away from the foundations of the house so that it was safe and efficient.

The project took one day to install and now Vernon and June and go ahead with their dreams for remodeling their basement. 

Geo-Lock Eases Homeowner's Mind

Rod of Gretna, NE became worried when he noticed water damage to the walls of his house. He originally thought that it might have something to do with his bowing and leaning walls, but he later learned that the two problems were unrelated. His foundations for his walls was unstable which was causing cracks and sinking in the pavement of his patio. After he called Thrasher, they helped him devise a plan that would fix his bowing walls and sinking patio.

The first part of the project that was tackled was the sinking patio. PolyLEVEL was injected under the patio to help keep it from sinking anymore and to raise it up to the level it should be at. Next, the bowing walls were remedied by installing Geo-Lock wall anchors and extension rods. Geo-Lock walls anchors are inserted in the ground below the walls and work to correct bowing and leaning walls over time. The drywall that was damaged by the water was cut out and Rod received utilities protection.

The project took a two days to complete in its entirety. Rod no longer needs to be concerned about his bowing walls or his patio which will stay stable for years to come. 

Family Looking To Sell House Protects Against Radon

Jahn of Gretna, NE heard about the dangerous and harmful effects of radon in the household and tested to see if his house was at risk, since he wanted to put it on the market. When he determined that it was, he decided that he needed professional help to ensure that he and his family would not be at risk in their own home. He called Thrasher help him resolve the problem.

Thrasher installed a basic radon mitigation system that would filter and pump out any radon that is in the air. This ensures that Jahn does not have worry about his he or his family being at risk for the harmful effects of radon. Radon is known to be one cause of different kinds of cancer and thus it must be taken seriously and it must be removed from homes that have high levels of radon.

The project only took one day to complete. Thanks to Thrasher, Jahn and his family can rest easy knowing that their home is protected against radon. 

Homeowner Put At Ease About House Foundations

Paul of Gretna, NE became concerned when she saw cracks in her basement walls. She knew that this was the result of poor foundations and knew that she needed professional help and fast. After talking to a contractor friend of his, he called Thrasher to see if they could help him fix his problem.

The cracking walls needed supports underneath them, so expansion joints were installed to prevent any shifting in the foundation, especially if there was an earthquake or any other natural disaster that could cause instability in the supports of the house. The expansion joints will also help keep the foundations of the wall stable which resolved the cracking in the walls.

The project took only one day to install. Thanks to Thrasher and their product, Paul isn’t worried about his house’s foundations. 

Foundation Cracks Stabilized by Geo-Lock Wall Anchors in Gretna Home

Homeowner Matthew M. was experiencing foundation troubles in his home.  He noticed that a wall  was bowing inward & had some serious cracks in it.  He wanted to take care of the problem before it could get any worse. While watching t.v. one day he saw a commercial for Thrasher Basement Systems.  

Later that day he contacted Thrasher and scheduled an appointment to meet with foundation repair specialist Johnny Stevens. Johnny inspected the home and recommended having Conor Casey and his crew install Geo-Lock wall anchors. Wall anchors are used to stabilize and straighten bowing walls. Anchors are embedded into the soil away from the foundation wall. Then connected to steel wall plates with anchoring rods. The anchors will hold the wall in its current position and straighten the wall over time.  

Matthew was glad he decided to contact Thrasher and no longer has to worry about the problem getting worse. They got the job done in a timely manner and treated his home like it was their own!
