Screw piles for a private house - reasons for choosing, installation
Building a house begins with a survey of the site. Unstable upper layers lead to the decision to install a pile foundation. In search of varieties, they stop at screw structures, which are ideal for creating a reliable foundation.
Reason to install
Conducting geological and geodetic studies should provide comprehensive information about the composition of soils, the proximity of underwater sources, the state of the relief, the availability of roads and communications.
Problems begin to come to light after laboratory tests. Samples taken may show the presence of:
- clay;
- sand;
- sandy loam;
- peat;
- loam.
The situation is aggravated by the presence of small stone fractions. It is impossible to build a strip foundation due to increased risks. In a few years, destruction will simply happen.
Screw piles will be able to perfectly strengthen themselves in problematic soils due to their special design. Blades of different widths are able to stay in the ground, preventing movement. They are not afraid of groundwater and flooding.
Based on research, screw piles of the required modification are selected. The online store has a wide range of products. Prices for wholesale screw piles, from the manufacturer are indicated in the price list. The system of discounts will allow you to save money when ordering a wholesale batch.

Installation details
The installation of a screw foundation is somewhat different from the installation of driven piles. Here you can not do without special equipment. The hammer, after a series of blows, drives the product into the ground, the pointed end allows you not to make a hole.
Screw piles need to be screwed in with little effort. First you need to decide on the number and type of location. The design allows you to make a base for a fence, a bathhouse, a summer kitchen, a garage, outbuildings, a gazebo, a veranda, a house.
We will have to calculate with maximum accuracy the weight of walls, partitions, floors, truss systems, roofs, communication equipment, household appliances and residents. Creating a margin of 20-30% will allow you not to worry about increasing loads in a few years.
The wall thickness varies between 4-10 millimeters. Cast products are better suited for the home, welded ones are less durable. The characteristics indicate the margin of safety. You need to divide the total amount and find out the approximate number of piles.
The type of arrangement can be different - single, tape, bush, pile field. Depending on the object, the appropriate option is selected. The created scheme should help to markup, make small holes to speed up installation.
Three people can do the installation. At the first stage, one needs to guide and hold the pile. Two long levers are inserted into the upper part to help twist. The foundation can be completed in one work shift.
