Thrasher Foundation Repair Before & After
  • Cellar Waterproofing in Lesterville, MO
    Cellar Waterproofing in Lesterville, MO

    Cellar Waterproofing in Lesterville, MO

    A homeowner in Lesterville, MO called us out because his cellar had problems with water intrusion for several years. After he decided it was too much of a problem and too timely to handle himself, he looked into our solutions and determined that with our decades of experience and our warranties that we would be a good fit to solve his unique cellar water problems. We sent System Design Specialist Nick Tiberghien to inspect the cellar and determine how to best prevent water from flooding it. Upon inspection, Nick found that the water intrusion was due to cracks in the walls and floor as well as the one path downhill to enter and exit the cellar. Cellars are easily flooded as they are fairly exposed to the elements more so than a basement and their single entrances usually lead downhill, providing an easy path for water to flow through. Nick talked to the homeowner about this problem and told the homeowner of our interior waterproofing solutions that could help prevent water from pooling once it entered the cellar. The homeowner was grateful that we proposed solutions and wanted to help him, so after his approval, our team got to work on installing waterproofing solutions. Our installation team utilized a full perimeter WaterGuard Drainage System with a Lateral Line to address all water that was coming through the cold joints and cracks. After this, the team worked to install CleanSpace Vapor Barrier to prevent water from coming through the wall cracks, as well as to help minimize the amount of moisture coming through the walls and reduce the relative humidity of the cellar. Finally, our team installed an Ultra Sump Pump with a buried discharge pipe to redirect all water coming into the cellar back outside. The homeowners were very happy with the solutions our team was able to install. They said that is was the best because he had previously tried other solutions that failed. The homeowner now has the peace of mind that he won't have to worry about cleaning his flooded cellar every time it rains now. Check out this unique cellar transformation!

    Foundation Repair in Lebanon, MO

    Barbara H. is a homeowner in Lebanon, MO, and wanted peace of mind knowing her basement would stay dry year-round as the transition began into the colder seasons. She had some concerns with water infiltrating the home’s foundation, so she gave us a call to thoroughly inspect the property. System Design Specialist Chris Bolander arrived at the home in Lebanon, MO, and determined that the downspouts were releasing water next to the home’s foundation causing extreme saturation levels in the soil. To permanently solve this issue, our crews buried each downspout 10 feet from the house to release the captured water far from the home’s foundation walls. Barbara was very pleased with her Thrasher experience and was relieved to know that her basement would stay dry throughout each year.

    Basement Waterproofing in Versailles, MO

    Homeowner Nevin is beginning to buy and flip houses, and it's important to him to do it right. In this home, he wants to finish the basement but wants to address waterproofing it first. When talking to a few different companies to find the best one to get the job done. He chose Thrasher because of our reputation and clarity when discussing the scope of work.  Anthony Salcedo inspected Nevin's house. He found the basement had leaking walls and a leaning foundation wall. The best action plan was to install an entire perimeter of wall supports, a complete perimeter drainage system, and a sump pump.  We installed our water guard system, CleanSpace, to divert any water intrusion through the wall and then installed a sump pump with backup. Next, to fix the leaning foundation wall, we established an entire perimeter of wall anchors to take the weight off and stabilize the failing wall. Nevin was pleased with the results and happy he chose Thrasher.

    Foundation Piering Stabilized the Historic Public Library

    Foundation stabilization by Thrasher was an integral part of the repair and restoration of the historic Sedalia Public Library. Parts of the structure had settled 5″. The extreme drought that began in the late spring of 2012 had devastating effects across the Midwest, particularly on lawns, crops and foundations. One building hit particularly hard was the Sedalia Public Library. The Sedalia Public Library is a prized building to the local community, and it has been listed on the National Register of Historic Places.   The Sedalia Public Library is located at 311 W. Third St, Sedalia, Missouri. The Sedalia library was first founded in 1895 but was located in the basement of the Pettis County Courthouse. In the Fall of 1899, they were awarded a $50,000 Carnegie Grant to build a new library. This was the first grant to be awarded by Andrew Carnegie in the state of Missouri.  “We were told by the structural engineer that we were in imminent danger of collapse.” – Library Director Pamela Hunter, in an interview with KMBC-TV. That grant money allowed the residents to build the then-new library. The library is built in the Greek Revival Style of architecture and was constructed of ornate white terra cotta stone with a limestone foundation.  The library was dedicated in 1901 and has been operational ever since, serving the citizens of Sedalia and the greater Pettis County. That is until the concerns over foundation problems arose in 2012.   Foundation problems were first identified in 2012 when a construction worker found "extremely wide" cracks in the foundation in one area of the library. The worker's concern led to a full investigation and, ultimately, the discovery of other severe foundation issues throughout the library.  The library hired a geotechnical engineer to investigate the site subsurface. During the investigation, it was determined that the soil's extreme dryness around the building's perimeter was a significant factor in the ongoing foundation settlement. Further investigation revealed that the underlying bedrock also had large voids beneath them. These large voids were likely the hidden contributor to the over 5" settlement throughout the years. As the corner of the library had settled, it also rotated outwardly and put the foundation and structure at extreme risk of collapse.  Previous attempts by other contractors had been made to correct the foundation settlement issues. Some of the attempted repairs included installing an extensive supplemental concrete footing, along with an elaborate below-grade watering and de-watering system. The supplemental concrete footing and watering system were combined with stabilizing the foundation and controlling below-grade moisture. While well-intentioned, the previous attempts were unsuccessful. The supplemental footing's added weight may have even exacerbated the settling issue, as evidenced by the continued settlement. The engineers were determined to solve this settlement issue permanently and to protect the historical landmark.   The recommended solution from the engineers was to install a customized micropile system. The plan was to bypass the shallow, unstable soils and fully transfer the foundation load's weight to the competent and stable bedrock. To achieve this result, any piering system would have to be drilled and advanced through the shallow rocks.   Thrasher was selected to perform this stabilization work due to their experience and expertise in micropile installations. Thrasher stabilized the building by first drilling through shallow rock formations and the underlying voids. Thrasher had to drill to depths of upwards of 40 feet to get into competent rock. Forty-nine high-strength steel resistance piers, with an ultimate capacity of 140,000 pounds each, were installed through the pre-drilled holes. The piers were then grouted with high-strength grout to add further lateral and vertical stability to the system. Once the exterior foundations were stabilized in place with the pre-drilled piers, the interior columns, which had not settled, had to be lowered to put the building on a uniform plane. Finally, the unstable soil excavated during the piers' installation was removed and replaced with suitable fill soil. The result was a permanently stabilized exterior foundation, and interior columns all leveled out to a uniform plane. Sedalia citizens could now rest easy that their historic library was finally placed on solid rock and would not move in the future.    When choosing a contractor to repair your building's foundation, it is not only important to choose a contractor who has the right repair product for the situation, but it is also essential to select the contractor with the right expertise and experience. When choosing to work with Thrasher, you are selecting a contractor who not only knows how to do the work correctly but has over 45 years' experience doing this type of work. So don't leave the work to a beginner. Hire the trusted name in the industry, and call Thrasher.
