Screw piles may be the answer you need if your home’s foundation is unstable but you’re concerned about the expense and inconvenience of a complete replacement. They provide an easy and fast way to stabilize your building without ruining your yard or breaking the bank.
Screw piles are made of metal rods driven into the ground that have helical blades on them. Even in difficult soil conditions, they are made to support and distribute the weight of your building, giving it a strong foundation. This technique is quicker than traditional foundation work and causes less disturbance.
In this post, we’ll look at screw piles’ operation, financial benefits, and practical applications for strengthening the foundation of your house. Screw piles could be the wise choice for your renovation project, regardless of whether you need to upgrade or are coping with settlement issues.

When it is necessary to replace the old base with a new one?
Under the influence of loads and outside influences, even the most sturdy foundation eventually gives way while the house is in operation.
Reconstruction can be used to strengthen the weakened foundation in cases of minor deformations, but this usually results in subpar work and comes at a significant labor, time, and financial cost.
Indices that indicate whether the current power structure needs to be completely replaced:
- Numerous cracks appeared in the load-bearing walls.
- The house settled, as a result of which the geometry of its structural elements was disrupted.
- The foundation is visually badly damaged.
It is preferable to raise the structures to a new foundation right away rather than trying to repair them in such situations.
Why choose a pile structure?
Currently, pilings remain the most tried-and-true method of replacing the foundation. It should be noted that the technology is only appropriate for wooden and frame houses, as walls composed of brick and other heavy materials may collapse when the loads are lifted from the old foundation.
The following are the pile technique’s benefits:
- high load-bearing capacity of power elements;
- possibility of construction on almost all types of soil, except rocks;
- sufficient stability in areas with moisture-saturated soil;
- availability and low price of building materials.
What is the advantage of such supports?
The foundation can be replaced with bored, pressed, or screw piles; the main distinction is in how the piles are installed in the ground.
Benefits of the pile-screw method:
- efficiency;
- sufficient load capacity;
- high construction speed;
- lack of excavation work;
- additional compaction of the soil during the process of screwing the blades;
- maintainability;
- Possibility of dismantling for reuse.
You must consider the primary drawbacks of alternative technologies in addition to the benefits of screw piles as stated above:
- to install bored piles, it is necessary to drill wells and wait 2–4 weeks for the concrete solution to gain strength;
- it is almost impossible to reliably calculate the bearing capacity of bored supports;
- To press in composite augers, it is necessary to use self-propelled special equipment, which is quite problematic to drive into an area with high building density.
Turnkey service price
The overall load that the structure places on the load-bearing structure is one of the pricing factors in this instance:
| Type of construction | Cost of lifting a house with an area of 4 by 6 m2, rub. |
| Panel building | 19400 |
| Frame house | 25500 |
| Construction made of timber | 28300 |
The prices displayed are merely estimates; in actuality, the cost of laying a new foundation will also depend upon:
- geological conditions at the site,
- parameters of structural elements,
- scope of work, etc.d.
Stages of work
Marking the area for a new pile field is the first step in the field work to replace the old power structure with piles. Support markers are positioned 20–40 cm away from the home’s walls. Subsequently, they move straight on to piling.
Drilling holes in the ground and filling them with compacted sand is the process of creating bored supports. The wells are filled with inventory pipes, which will act as formwork.
Inside, a reinforcement frame is positioned and mortared. I then remove air bubbles from the concrete by bayoneting it.
Stages of screw pile installation technology:
- Screwing the supports into the ground to the designed depth.
- Trimming the top ends of piles at the same level.
- Concreting the internal cavity of pipes.
- After the solution has hardened, welding of the ends.
- Coating a metal structure with a hydrophobic composition.
Once the power elements are prepared, replace the old foundation in the following stages:
- lifting the house with jacks;
- installation of supports under the basement floor;
- laying I-beams on pile heads under the walls of the house parallel to each other;
- fixing the metal structure with welding seams;
- cleaning of welding seams, coating with waterproofing material;
- lowering a house onto a new foundation.
Features for columnar and strip foundations
The method previously described is the same technology used to replace columnar and pile foundations with new supporting elements. The previous foundation may be left in situ or disassembled to the ground level upon the construction of a new power structure.
In order to make room for jacks, it is necessary to destroy some of the weakened foundation before raising the house from its strip foundation. To lessen the strain on the supporting soil layer, experts recommend removing the old supporting structure as much as possible below ground level.
Is it possible to replace it yourself and is it worth it??
An expert assessment is necessary before replacing the foundation with piles. A specialist comes to assess the extent of the structure’s damage and create a work schedule.
Most of the time, a house has to have its corners tightened and supports installed in window and door openings before it can be raised. In order to prevent deformation of the stove heating system, if the building has an operational stove, the attic floor and a portion of the roof surrounding the chimney are disassembled.
It is essential to perform new engineering calculations and choose new power element parameters prior to moving forward with reconstruction. Generally speaking, only a highly skilled professional can arrange the complete set of listed works.
If the dependability and lifespan of the structure are unimportant, you can replace the foundation on your own. If the owner starts work without the necessary knowledge and expertise, there is less chance that the walls will align correctly, which could result in the collapse of the entire house. Additionally, mistakes in design and calculations could make the project unfeasible in its entirety.
Average construction cost
Each technique for using piles in place of foundations is evaluated separately for effectiveness. To familiarize yourself with the technology’s features and make an initial evaluation, utilize the prices listed in the table:
| Building area | Foundation replacement cost | |
| on screw piles | on bored supports | |
| 3 by 3 m | 19100 | 24800 |
| 3 by 4 m | 23700 | 30800 |
| 3 by 5 m | 34800 | 32250 |
| 6 by 6 m | 30500 | 39600 |
| 6 by 8 m | 40600 | 52750 |
| 8 by 8 m | 54200 | 70400 |
