When choosing a foundation for a house, special attention is often paid to pile-screw foundations - due to the combination of ease of installation, versatility and resistance to difficult soil conditions. If we are talking about a frame house, then a pile-screw foundation becomes one of the most rational solutions. This foundation for a frame house is a universal solution that combines ease of installation, resistance to difficult soil conditions and the ability to work at any time of the year.
What is a pile-screw foundation
A screw-pile foundation is a structure based on metal piles with screw tips that are screwed into the ground to a pre-calculated depth. Such piles serve as a support for the grillage - the supporting frame, on which the frame of the house is subsequently mounted.
The design consists of three key elements:
-
Metal piles with screw blades - they ensure reliable screwing into the ground and resistance to horizontal and vertical loads.
-
Braces (grillage) - connects the piles into a single system and evenly distributes the load from the superstructure.
-
Anti-corrosion protection - ensures the durability of the metal when used in conditions of high humidity.
Advantages of a pile-screw foundation for a frame house
1. Quick installation
A screw-pile foundation can be installed in a matter of days, and does not require lengthy preparation, pouring concrete or complex excavation work. This is especially true if it is necessary to reduce construction time and avoid seasonal delays.
2. Independence from ground conditions
This type of foundation has proven itself well on heavy, heaving or unstable soils, where other types of foundations may require significant preparation costs - for example, backfilling or drainage of groundwater. The piles are screwed into dense layers, providing a stable foundation.
3. Minimal disturbance of the terrain
During the installation of a pile-screw foundation, large-scale excavation work is not required, so the natural topography of the site is preserved. This is especially important if the site is located on a slope, in a wooded area or close to water bodies.
