Designed for foundations of various types of buildings, they are suitable for the construction of cottages, residential buildings, industrial buildings, bridges, piers. For the production of a foundation on screw piles, earthworks are not required, piles can be screwed into the ground using a special rotary device powered by 220 volts or installed on a manipulator vehicle, and in hard - to - reach places, piles can be screwed manually using a long wrench. Piles can be installed in any weather and at any time of the year, despite the frozen ground. The number of piles per building depends on the soil and the type of building, its height, their number is usually calculated by the building designer. Foundations based on screw piles have high reliability, durability, and are many times cheaper than reinforced concrete foundations.
