Job Stories From Grand Island, NE
PolyLevel Makes a Safe Driveway For Grand Island Homeowner

Dean E., a policeman in Grand Island had a driveway made up of six concrete panels.  One of the panels closest to the garage had a large crack in it and was starting to settle causing a 2 inch ledge.  Being a policeman he knew of the legal actions that would be taken against him if someone fell and got injured due to the gap.  He knew something had to be done ASAP to fix it. After a quick search online he knew who to call, the professionals at Thrasher Basement Systems. 

Not too long after the call, specialist Brian Marron was out to Dean's home to inspect the driveway.  The solution he close was quick and simple.  This was to have foreman Collin Crouch come out and to lift the slab back up with the PolyLevel system.  This is done by drilling small (penny sized) holes in the slab using specially designed equipment to inject a structural grade polymer into the void. After the void is filled, the expanding properties of the polyurethane allows for an accurate lift and leveling of the slab.

Dean no longer has the worry of others or himself falling and getting hurt all thanks to this simple system by Thrasher Basement Systems!

We are purchasing a home at the listed address above and had a reading of 5.3 on the radon test we had conducted.

Basement walls bowing in.

We have a bowing block wall in our house, we need to get an estimate to get the walls repaired and somewhat water proofed. Thanks
Stoneridge Path in Grand Island
I have a storeroom in the basement that always smells musty. I run a dehumidifier in the Spring when it is wet outside. It has an opening to the crawl space that I cannot close up because of mechanicals running thru the opening. I just sent in a radon test and am presently waiting on the results. It doesn't really matter the results as I need something done to ventilate/seal the crawl space. I also have noticed mold on the return air vent. My family is gone and I need to "down-size", but I do not want to pass this problem on to the next owner. Please call to set up a time for inspection and estimate. Thanks! Janet

We had an at home radon test that was 4.8 pCi/L. It was recommended that we have another test and fix the problem.
Villa Mar Dee Ave in Grand Island
Our house has a full unfinished (partially finished with framing and upper drywall in areas). It has a sump pump pit with I believe a 1 hp pump and a 1/2 hp submersible pump. The smaller pump pipes into the sewer/storm drain? and the other outside. The house also has a tile drainage system? (I think that's what it's called) in the foundation. We get water in the basement during heavy rains (2-3 inches last year). The water does not come through the walls. It seems to come out of the sump pump pit (our sump pumps can't keep up). And up through a crack in the floor when it water gets so high. A few smaller cracks seep some. We would like to eventually be able to finish the basement.
Scheel Dr. in Grand Island
My basement leaks water through the floor when it rains alot. The floor is concrete and there are some big cracks that the water comes in from. The walls are block and they do not leak. The basement is partialy fineshed with studs and drywall. I was just wondering if there is something that you can do about the floor and the cracks that are letting in all the water in the spring?
S. Blaine in Grand Island
We have a dirt crawl space that smells kind of bad (especially in the summer), is very dusty, and is just unpleasant to use for storage. We'd like to investigate encapsulation. Also, we'd conducted a radon test last winter and found the radon level to be slightly elevated. Perhaps encapsulation might help with that too. Thank you

Ground water in basement
Zola Ln. in Grand Island
We have lived in our house for about 5 yrs. (July 2005) and for the past 3 yrs. we've had a lake in our crawl space. The water level goes up and down periodically but never completely gone. We've had other professionals out but say it's ground water and to let it be but we want another opinion.
