Is it possible and how to raise a house on screw and bored piles, how much does it cost??

Although raising a house can seem like a difficult undertaking, there are many situations where it is a useful solution. Elevating your home can have a lot of advantages, whether you’re trying to protect it from flooding, have a sinking foundation, or just want to add more space. The use of screw and bored piles is one efficient technique for this. But what precisely is involved in this process, and how much should you budget for it?

Deep foundation systems that give structures strong support include screw and bored piles. Bore piles are created by drilling a hole and then filling it with concrete; screw piles are made of large metal screws driven into the ground. These piles provide a stable and long-lasting way to raise a house. This approach is especially helpful in places where conventional foundation techniques are impractical or where the soil is unstable.

Raising a house on screw and bored piles is a multi-step process. First, hydraulic jacks must be used to carefully lift the house. The screw or bored piles are positioned underneath the house to give support after it has been raised to the appropriate height. To keep the house safe and level, this calls for accuracy and knowledge. The house is lowered onto its new foundation once the piles are in position.

The price of raising a house on bored and screw piles varies greatly based on a number of variables. The price depends on a number of factors, including the weight and size of your home, the kind of soil, and the particulars of your land. You should budget, on average, between $20,000 and $50,000 or more. To fully grasp the project’s scope and related expenses, quotes from qualified contractors are imperative.

All things considered, many homeowners may find that raising a house on screw and bored piles is a practical and efficient solution. In the long run, it can help safeguard your investment by addressing fundamental problems. Even though it’s a significant task, having a solid and safe home foundation can have far-reaching advantages that exceed the expenses and work required.

Why do you need to raise a building??

Over time, the integrity, strength, and reliability of the structure deteriorate due to the foundation bearing the majority of the loads during its operation.

Requirements for replacing or repairing the old foundation:

  • uneven settlement of the house around the entire perimeter;
  • numerous cracks in the walls of the structure;
  • visible destruction of the old foundation;
  • misalignment of door and window openings.

The load-bearing structure’s natural aging process, technological errors made during design and construction, shifting loads, or the site’s hydrogeological conditions are the main causes of the deformations mentioned.

Once the old foundation has reached the end of its useful life, it must be reinforced or replaced. The decision to raise the building on new supporting elements is made after evaluating the extent of the damage.

This approach typically enables you to resolve issues quickly and for the least amount of money and labor. Another good strategy to protect a house’s structural integrity in the event of flooding is to raise it off the ground.

What supports to use?

These load-bearing structures are selected from among the various types of pile foundations that are currently available because their installation prevents further force loads and vibrations that might destroy the house and weaken the soil. Houses are not raised on driven piles in accordance with this principle.

The technology of raising a house on bored or screw supports is applied in private housing construction. The first method’s implementation will cost a lot of money in labor and time. In addition, the durability and strength of bored pillars are directly related to the quality of the concrete, the dependability of the reinforcement frame, and the installation’s adherence to SNiP regulations.

The majority of licensed developers provide services for raising homes and cottages onto their own pillars, which is significantly less expensive, simpler to execute, and requires two to four days of labor. Pile foundations are unique in that they are useful for construction on a variety of soil types.

For homeowners wishing to elevate their property or stabilize their foundation, screw and bored pile raising is a feasible option. Using this technique, a strong foundation that can support the weight of the house is created by either boring and filling bored piles with concrete or driving steel screw piles into the ground. The size of the house, the state of the soil, and the particular materials used can all have a significant impact on the project’s cost, which typically ranges from $10,000 to $50,000.

What kind of houses can be put on a new foundation??

Wooden walls for low-rise structures can be erected on a new pile foundation (frame, panel, timber). Because wood is a plastic material, structural elements made of it can usually withstand loads and, in the event of a roll, return to their original position without breaking.

In addition, the structure must be in acceptable condition; crumbling and partially destroyed homes cannot be moved to a new foundation.

It is risky to remove a building from its location if there are numerous cracks in the lower portion of the structure.

Additionally, keep in mind that cottages with walls composed of:

  • bricks,
  • aerated concrete,
  • foam concrete and other materials similar in structure.

There is a significant chance that attempting to remove such a structure will cause cracks and deformations, which could result in the house being completely destroyed.

Turnkey price

Since there are many variables that affect the cost of work, developers provide estimates based on typical circumstances.

For your reference, the average market prices to raise a wooden house to a maximum height of 20 cm above ground are listed below:

Type of construction Cost of lifting a house with an area of ​​6 by 6 m2, rub.
Panel house 68400
Frame house 72400
House made of timber 78400

What"s included in the price?

The following are the primary components that determine the cost of house lifting services:

  1. A specialist will visit the site to assess the degree of destruction of the old foundation.
  2. Test drilling of soil.
  3. Collection of data regarding hydrogeological conditions, as well as design features of the facility, with subsequent engineering calculations for a new foundation.
  4. Selection of optimal parameters for the load-bearing structure.
  5. Delivery of piles and other building materials to the site.
  6. Lifting the house on jacks, installing supports at the corners of the structure to avoid emergency situations.
  7. Partial or complete dismantling of a weakened foundation.
  8. Field marking and installation of supports at design points; screwing in screw piles, or drilling holes for rammed supports.
  9. Concreting screw piles or laying a reinforced frame with subsequent filling of wells with mortar.
  10. Aligning the base part of the pile foundation at the same level horizontally.
  11. Installation of pile heads followed by tying the supporting elements with a channel or wooden beams.
  12. Implementation of thermal and waterproofing of pile foundations.
  13. Lowering the house onto a new load-bearing structure.

The following variables will affect the price:

  • number and parameters of piles;
  • volume of work and weight of the structure;
  • consumption of building materials;
  • the need to remove heavy furniture from the house;
  • the need to strengthen the building, window and door openings to maintain their integrity.
  • the need to dismantle extensions to the house (veranda, summer kitchen, etc.).d.);
  • remoteness of the object, as well as the availability of sources of electricity and water supply.

The cost of the service is determined on an individual basis for foundation reconstruction based on numerous pricing factors.
