Different types of foundations are used for slopes, each with its own advantages
and disadvantages.
Strip Foundation on a Slope:
Construction Stages
Constructing a strip foundation on a slope requires careful preparation and
adherence to the proper procedures. Here are the main steps to help you
complete the process effectively.
1. Site Analysis and Layout. First, survey the site to determine the slope
angle and its features. Then, mark out the foundation outline, taking into
account the foundation depth and strip width.
2. Excavation. This stage involves excavating the soil for the foundation.
Keep in mind that on a slope, excavation may be deeper at the bottom of the
strip and shallower at the top.
3. Foundation Preparation. Compact the bottom of the pit and check the
level. If necessary, add crushed stone to improve drainage.
4. Formwork. Install the formwork according to the markings, securing it in
a vertical position. It must be strong and stable to support the concrete pour.
5. Reinforcement. Place reinforcement cages inside the formwork to increase
the foundation's strength. Use high-quality rebar that meets design
requirements.
6. Pouring the concrete. Pour the concrete mixture into the formwork,
distributing it evenly along its entire length. Ensure there are no voids or
air pockets.
7. Curing the concrete. After pouring, monitor the temperature and moisture
content of the concrete to ensure it gains strength. Moisten the surface
periodically.
8. Removing the formwork. After 7-10 days from pouring, you can carefully
remove the formwork. Ensure the concrete has completely cured and reached the
required strength.
By following these steps, you can build a high-quality strip foundation on
a slope, ensuring the strength and stability of your home.
Advantages of Screw Piles for
Building a House on a Slope
Using screw piles in buildings on slopes has significantly more advantages:
• Ease of installation. Screw piles can be installed even in hard-to-reach
places with minimal excavation. This is especially important when site access
is limited.
• Stability on soft soils. They are anchored deeper into the soil than
conventional foundations, providing reliable support. This makes them suitable
for use in high-moisture and unstable soil conditions.
• Time savings. Quick installation reduces construction time, which is
important for many developers. Screw piles are ideal for completing projects on
time.
• Flexibility. Screw pile foundations can be used to build country houses,
summer cottages, saunas, garages, greenhouses, piers, and temporary structures.
Installing a Pile-Screw Foundation
on a Slope
Installing a pile foundation involves several key stages:
1. Pile foundation design: Developing a project taking into account the
slope topography and the weight of the house. Determining the number, diameter,
length, and type of piles, as well as grillage parameters, taking into account
the elevation difference. 2. Site preparation: Clear the site of vegetation and
debris.
3. Site marking. Draw the foundation outline on the ground, taking into
account all the dimensions of the future building. This will allow you to
accurately plan the placement of all piles. Additional slope stabilization work
can be performed if necessary.
4. Installation of screw piles. The piles are driven in using special
tools, either manual or mechanical. The driving process varies in time
depending on the soil density.
5. Pile height adjustment. Checking and adjusting the pile height at the
same level is necessary to ensure the grillage is level. This step is crucial
for the reliability of the structure and prevents distortion.
6. Installation of grillage. The grillage is made of concrete or metal
structures, which provides additional stability and rigidity to the structure.
It connects the piles into a single structure, distributing the building load.
7. Waterproofing: Application of waterproofing materials (roofing felt,
waterproofing membranes) to the grillage to protect against moisture. 8.
Finishing Work: Additional work to install a drainage system, backfill, and
landscaping the area, taking into account the slope's characteristics.
Building a foundation on a slope requires careful planning, geological
analysis, and a professional approach. Proper selection of the foundation and
adherence to installation technology guarantee the reliability and safety of
the structure. Screw piles are the best choice for steep slopes, providing a
cost-effective and reliable foundation for the home. By following these
recommendations, you can build a home that will last for decades.
