To guarantee a smooth process, we will walk you through the device setup in this article and provide clear drawings. A solid and long-lasting foundation for your building needs can be achieved by comprehending the fundamentals and adhering to these instructions.

Types of strip foundations and their scope

Ribbon foundations are more frequently utilized than pile or columnar varieties and are in high demand. Because of their availability, versatility, and capacity for independent construction, their primary use is in the private construction of houses.

Additionally, basements can be organized with the aid of these structures, converting them into extra usable space (for a garage, sauna, gym, or service complexes).

Installed as a solid strip, the foundation absorbs the weight of the floors and takes loads from the building’s exterior and interior walls.

Prefabricated and monolithic foundations have different operational characteristics and methods of arrangement. A preliminary frame with reinforcement and concrete screed is built when building the first kind of structures. Due to the need for developers to arrange formwork, a frame, and prepare concrete, the production process is more intricate and time-consuming.

Special blocks made of reinforced concrete serve as the foundation for prefabricated reinforced concrete strip foundations. As a result of reinforcement and concreting, they come together to form a precast monolithic foundation.

Instead of using metal reinforcement, modern construction typically makes use of cutting-edge composite materials, which are known for their increased strength and low weight. Additionally resistant to moisture and harsh conditions are composites. Rods can weigh five times less than their metal equivalents of the same diameter.

Additionally, foundations are categorized into shallow and deep options based on their depth.

Numerous factors, including the soil’s bearing capacity, influence the placement depth. It is advised to use deeper foundations that are installed 30 to 50 centimeters below the freezing point when setting up a foundation on heaving soils, which have the tendency to expand and contract due to temperature fluctuations.

Since the building’s estimated mass affects the structure’s load, it is also taken into consideration. Shallow foundations are permitted for light buildings on slightly heaving soil.

What does a prefabricated foundation consist of

The components of a prefabricated strip foundation are as follows:

1. Trapezoidal pillow blocks. Their task is to expand the supporting area of ​​the base.
2. Reinforced concrete blocks with a rectangular shape and reinforcement. They are used to increase the height in the recess.

One block may weigh up to 300 kg, so maintenance and transportation will require specialized tools. Blocks are used in the layout of technical rooms, residential buildings, basements, and subterranean parking lots because of their many benefits.

Advantages and disadvantages

Prefabricated strip foundation is frequently utilized in construction projects because of the following benefits:

1. Increased speed of construction. For the arrangement of prefabricated foundations, ready-made blocks are used, which speeds up the construction process. After connecting the elements, you can move on to other work.
2. High quality assembly and reliability. All prefabricated blocks are checked for compliance with GOST standards and undergo strict quality control.
3. Long service life.

1. Reduced strength properties in comparison with monolithic analogues.
2. Deteriorated heat and moisture insulation due to the presence of seams between the blocks.
3. Expensive transportation. In some cases, the construction of prefabricated foundations is more expensive than monolithic ones, since their delivery to the site requires large expenses, and assembly is carried out using a crane.

What is better: a prefabricated or monolithic foundation

Both kinds of foundations have advantages and disadvantages, so you must consider many different aspects and subtleties before making your decision. When there are no apparent heavy loads on soft, sandy, or marshy soils, a structure composed of prefabricated blocks is in demand. A two-story house can also be built on top of it. What matters most is that the material possesses the necessary level of strength and dependability.

A monolithic structure can last more than 100 years, but a strip of blocks has a 50–75 year service life. This is because the monolith is made up of vulnerable joints and no seams. This configuration gives the structure more strength and enables it to be installed beneath a large building.

FBS foundation plan

A plan and several drawings must be created in order to arrange prefabricated strip foundations. This phase of the construction is essential because without it, you are unable to continue working. The future foundation’s features, production technology, and other details are outlined in the document.

1. Depth of the foundation placement.
2. Configuration, dimensions and features of the constituent elements.
3. Placement and diameter of holes for communications.
4. Number and specifics of installation of pillow blocks.

You can complete the tape assembly process more rapidly by working with the established plan as a guide.

Tools and materials

A variety of instruments and supplies are needed to lay the foundation before building can begin.

1. Shovel
2. Crowbar.
3. Buckets.
4. Building level and plumb line.
5. Rope, stakes and hammer.
6. Level.
7. Concrete mixer.

Among the consumables on the list are:

1. Sand.
2. Gravel.
3. Cement.
4. Waterproofing material.

Types of foundation blocks

The foundation blocks listed below are available for purchase:

1. Monolithic models of FBS blocks – are a solid structure with steel reinforcement. Demonstrate the maximum degree of strength.
2. Monolithic with a groove (FBV) – also built on the basis of reinforced concrete, but their design provides for the presence of cutouts for laying communications.
3. Hollow (FBP) – are distinguished by the presence of cavities inside. Due to their low strength, they are not used for the construction of foundations and are in demand only for the arrangement of light frame or wooden buildings.

You must consider its features and your ability to read abbreviations when selecting a foundation material. The structure is 20 cm in length, 20 cm in width, and 40 cm in height, according to the FBS 2-2-4 indicator.

FBS 4, 6, 8, 9, 12, 24 are used when arranging concrete blocks for a strip foundation with steel reinforcement. The anticipated loads from the future building define the precise grade.

In the construction of low-rise buildings, 20x20x40 block indicators are typically used. They can be used to arrange basements, partitions, and other structures. They are made from crushed granite stone.

Device

An analysis of the soil is required prior to beginning the installation of a strip foundation. Such a structure can be installed on any type of soil, including heaving soil, provided the installation technology is used correctly.

Installation on soils with rocky rocks and deep groundwater, however, is the best choice. If not, even with excellent waterproofing, the basement structure will be exposed to high humidity.

1. A monolithic layer of concrete is fixed on top of the foundation and additionally leveled. Then bricks or cinder blocks are installed.
2. The sinuses between the blocks and the soil should be filled with coarse-grained sand.
3. The outer surface of the foundation is treated with waterproofing materials. Bituminous mastic or resin are used as such.
4. The foundation needs additional insulation with polystyrene foam or another insulator.
5. The joints are sealed.

Careful planning and execution are required when utilizing reinforced concrete to create a prefabricated strip foundation. You can guarantee a solid and stable foundation for your building project by adhering to the specified procedures.

Accurate measurements and a well-drawn plan are essential first. By doing this, it is guaranteed that the foundation will be level and strong enough to support the structure above it. To prevent any errors during the building phase, pay close attention to the details in the drawing.

The next crucial steps are putting the reinforcement bars in the proper location and assembling the formwork. A foundation that is properly reinforced is able to bear different kinds of loads and pressures. Make sure you place the reinforcement in accordance with the suggested guidelines.

Lastly, the most important step is to pour the concrete mix and let it cure properly. Make sure the concrete is poured evenly and without any air pockets. The foundation will acquire the required strength and durability if it is properly cured.

Following these instructions will enable you to build a dependable and long-lasting prefabricated strip foundation. This approach guarantees stability and longevity by giving any construction project a strong foundation.
