How to Raise a House on Screw Piles

Screw piles are metal structures used to strengthen the foundations of buildings and structures. They can be installed quickly and easily, making them an ideal choice for projects that require a fast and effective solution.

When is it Necessary to Raise a House?

House raising may be necessary in the following situations:

• Foundation Settlement: If the house's foundation has settled or sunken, which can lead to cracks in the walls and floor, the house must be raised to restore it to its original position.

• If the house's foundation has been damaged by natural disasters, such as earthquakes or floods, or by construction errors, the house must be raised to repair or replace the foundation.

• If you want to increase the ceiling height of your house or add another floor, you must raise the house to create space for the new structure.

• Foundation Rebuilding: If you want to change the type of foundation, for example, from a strip foundation to a pile foundation, you must raise the house to carry out the necessary work. • If utilities such as water, sewer, or electrical lines running beneath the house need to be repaired or replaced, the house must be raised to access these utilities.

• Soil Heave Mitigation. If the house is located on soil prone to heaving, it must be raised to mitigate the effects of heaving and prevent further damage.

• Preparing for Relocation. If the house needs to be moved to a new location, it must be raised to prepare for transport.

• If a historic building needs to be restored, the house must be raised to perform the necessary work to restore and preserve its original condition.

In each of these cases, a thorough analysis and assessment of the house and foundation condition is required to determine the best method for raising the house and performing the necessary work.

House Lifting on Screw Piles

House lifting on screw piles is a process that allows an existing house to be raised and installed on new screw piles, thereby providing a strong and stable foundation for the building. This process is often used for homes built on weak or unstable soils, or for homes that have suffered from settlement or other geological issues.

Stages of house lifting technology on screw piles:

• Preparation. Before work begins, a thorough inspection of the house and its foundation is conducted to determine the need for lifting and determine the optimal locations for installing the screw piles.

• Installation of temporary supports. To ensure the safety and stability of the house during lifting, temporary supports are installed to support the house and prevent it from collapsing.

• Excavation. Holes are dug for installing the screw piles. The depth and width of the holes depend on the type of screw piles and the geological conditions on the site.

• Installation of screw piles. The screw piles are installed in the holes and screwed into the ground to the required depth. Screw piles can be made of various materials, such as steel or reinforced concrete.

• House lifting. After installing the screw piles, the house is raised using hydraulic jacks or other specialized equipment. The lifting is done gradually to avoid damage to the house or its foundation.

• Installing the house on the screw piles. After the house is lifted, it is placed on the screw piles, which provide a strong and stable foundation for the building.

• Anchoring the house. The house is secured to the screw piles using specialized fasteners, such as anchors or bolts.

• Foundation restoration. After installing the house on the screw piles, the foundation is restored to provide additional support and stability for the building.

• Final inspection. Upon completion of the work, a final inspection is performed to ensure the house is correctly and safely installed on the screw piles. Advantages of raising a house on screw piles:

Improved foundation stability and strength

• Prevention of further settlement or damage to the house

• Possibility of installing a house on weak or unstable soils

• Reduced risk of collapse or damage to the house

• Increased service life of the house

Disadvantages of raising a house on screw piles:

• High cost

• Requires specialized equipment and qualified personnel

• Potential damage to the house or its foundation during raising

• Requires foundation restoration after installing the house on screw piles

Overall, raising a house on screw piles is an effective way to improve foundation stability and strength, prevent further settlement or damage to the house, and extend the lifespan of the building. However, this process requires specialized equipment and qualified personnel and can be quite expensive.
