Want to avoid problems.
Good morning! What are the most common mistakes people make when installing screw piles manually? Want to avoid problems.
Good morning! To ensure a strong and stable pile foundation, it's important to avoid these common mistakes. First, never unscrew the rods to level them - such a foundation quickly deforms due to uneven subsidence of the piles. Once a pile is screwed in, it must stay in place. Second, avoid installing the supports at an angle - in this case, the blades are pulled out of the soil under the influence of horizontal and vertical loads, compromising foundation integrity. Third, ensure screwing depth is at least 1.5 meters - the pile tip must pass the freezing level of the soil, otherwise frost heave forces will push it out. Fourth, cut piles strictly horizontally, not at an angle - pile tails must be cut horizontally to ensure correct level of pile caps, otherwise load on the foundation will be uneven. Fifth, perform correct load calculations - installing fewer piles or using supports with smaller diameter than required is unacceptable and trying to save money can lead to unpredictable consequences. Sixth, use only quality materials - supports made by hand or with deep scratches shouldn't be used as there's high risk of blades being torn off during installation, and damage to protective coating leads to wall thinning and rapid failure.
