Screw piles are suitable for constructing piers and docks, terraces, gazebos, bathhouses, and utility buildings. They have sufficient load-bearing capacity for frame and wooden residential buildings. And most importantly, they can be installed independently! No preliminary excavation work or heavy construction equipment required. However, installation work requires adherence to technical regulations; failure to follow these regulations will reduce the stability, safety, and service life of the foundation. TOP MOST COMMON MISTAKES made by amateurs when installing screw pile foundations: 1. FORGETTING ABOUT SOIL SURVEY Without a comprehensive geological survey, it is impossible to calculate the optimal pile driving depth. To perform its function of transferring loads to soil layers with sufficient bearing capacity, a helical pile's blades must reach dense rock and penetrate the winter soil freezing level. If the bottom of the pile becomes suspended in loose or water-saturat...
