When is the reuse of screw piles permitted Reusing screw piles isn't always possible, but in some cases it is. The main condition is that the pile maintains its geometry, metal integrity, and blade functionality. If these parameters are within specifications, the pile can last for several more years. Reuse is generally permitted: • Temporary structures. For example, pavilions, hangars, exhibition stands, and seasonal terraces. Such structures are often dismantled and reinstalled, making reuse of the piles entirely justified. • If dismantling is performed carefully. The pile should be unscrewed, not pulled out, otherwise the shaft may be deformed or the blade damaged. • When the pile's service life was short. If the piles have been in the ground for less than 1–2 years, the risk of corrosion and fatigue deformation is minimal. • ...
