Foundation Repair Photo Album: Helical Piers in Gallatin, TN
This homeowner in Gallatin, TN, contacted Frontier Foundation & Crawl Space Repair when they noticed cracks and separation happening around their home. After our skilled technicians evaluated the situation, they decided that installing helical piers would be the best solution. These specialized piers form a supporting base that transfers the weight of the home downwards to the supporting soil underneath. This will lift the foundation and stairs to practically their original position, removing the appearance of cracks and separation. To start, we excavated square-sized spots in the soil around the home, specifically in spots that needed support like the home's external concrete stairs. The crew then placed the helical piers so they can be "screwed" into the soil. Once a suitable depth has been reached, we position heavy-duty steel brackets underneath and against the foundation footing. The home's weight is transferred through the piers to the stable soil where it lifts the home, improving cracks and separation around the home.
