Is the material suitable for the basement?

The foundation of a building may be constructed using concrete panels and reinforced concrete. It is advisable to comprehend the composition of the panels in order to comprehend why the response to this query is affirmative.

In manufacturing, they are constructed from sturdy concrete in predetermined sizes and additionally reinforced with a unique metal mesh.

Strip foundations are ideal for this kind of basement. For frame and panel homes, slab construction is the most ideal method of basement construction.

Developers who use turnkey frame technology to build large-scale houses frequently use this type of building material for the basement walls. It is quick, dependable, and convenient as opposed to the drawn-out process of pouring monolithic concrete.

Slabs are made with a front and a back side. The customer may request that the front side have a relief, which helps to add pattern to the basement facade.

For which foundations and buildings is it not suitable?

For the construction of basements in homes with pile or screw foundations, reinforced concrete and concrete panels are not appropriate. Slabs are impractical in these kinds of foundations because a suspended structure is used instead.

Additionally, using this building material in areas with too-weak soil is irrelevant. Additionally, using such panels without hydro- and vapor barriers is not advised.

Types of slabs

Several characteristics allow for the division of all currently available concrete and reinforced concrete basement products:

1. by the purpose of the building itself;
2. by design;
3. by structure;
4. by the number of layers.

Markings are another way to identify panels. It is advised to take into account every group.

By the purpose of the building

These products can be categorized into the following categories based on the kind of building for which the basement is being built:

• For ground floors. Plinth slabs made of reinforced concrete or concrete can be intended for the ground floor of an apartment building. Such building material is highly reliable, fire-resistant and durable. It is reinforced with a steel frame. Can be made from different types of concrete, but often from the strongest grades.
• For technical basements. Panels for technical basements are designed in such a way as to not only withstand external pressure from the soil, but also withstand the load from floor slabs and other building materials used in the construction of the building.
• For attic spaces. For attic spaces, lighter concrete is used in the production of panels. This is due to the fact that the attic is located on the top floor and its load on the house should not be too large. Such reinforced concrete panels are often made of cellular lightweight concrete.

By design

Reinforced concrete panels are what they are by design:

1. Composite. They are also called prefabricated, since during the production process the material is assembled from several parts. In the product marking, they have the letter "C" at the end of the designation. Prefabricated panels are those that consist of several layers and are considered insulated.
2. Integral. Such products are called monolithic. They are made by casting concrete into special forms for slabs at one time.

It is important to note that integral panels are regarded as having a more durable design than composite ones, so it is best to use them when building the basement.

By structure

A concrete or reinforced concrete panel has a structure of its own that can be:

• Suspended. This type of panel is not intended to support other building structures on it. Only windows, doors and gates can be supported on it. This option is not very suitable for the construction of a basement, since it is the basement that bears a huge load from above.
• Load-bearing. A reinforced concrete structure can withstand vertical loads from its own weight, as well as from other building structures. For example, from floor slabs, roofing and wall panels located above. This is a good option for a basement.
• Self-supporting. Products are intended for the outer walls of the plinth and are able to withstand both their own weight and the load from other building materials located above. This option is also suitable for constructing the basement of a house.

By the number of layers

Products categorized by number of layers are:

• Single-layer. Made using autoclaved aerated concrete with good thermal insulation characteristics. These products are reinforced along the contour with a welded reinforcement mesh. The material is protected from the outside with a cement-sand mortar, and from the inside with a vapor-permeable decorative mortar.
• Two-layer. Consist of an inner supporting layer, in the production of which structural concrete was used. The outer layer is made of heat-insulating lightweight concrete. The thickness of the layers is at least 100 mm.
• Three-layer. Three-layer structures are made of heavy or dense lightweight concrete. The thickness of the outer layers depends on the operational purpose.

Two-layer slabs are used in dry, cold climates, and single-layer slabs are used in warm climates. The composition of three-layer slabs can alter their properties.

By marking

These panels, which are meant for cellar floors and basements, bear the following GOST markings:

• PSP – load-bearing solid;
• PSPS – load-bearing composite;
• PGP – non-load-bearing solid;
• PGPS – non-load-bearing composite.

Every slab that is sold at the factory has GOST-compliant markings.

Design requirements

GOST 12504-80 governs the specifications for basement panels made of reinforced concrete. The document highlights the following key points, which can be emphasized:

• PC-1 – marking of a basement panel made of reinforced concrete;
• production material – extra-heavy concrete grade M200, compressive strength B15;
• concrete is reinforced with steel grade A3;
• reinforcement is also carried out with a steel mesh made of Vr-I wire;
• the dimensions of the slab may vary: width about 600 mm, length 2750-2950 mm, thickness 70 mm;
• frost resistance class of concrete for production – F50;
• bursts and cavities on the panel should not exceed 3 mm;
• shrinkage cracks should not be more than 0.2 mm wide.

When accepting the goods, consider the following: the thickness of the concrete layer, the absence of cracks, the strength of the base material, the dependability of the welding, and the absence of exposed reinforcement. Panels are folded and transported vertically when being transported.

Materials and tools for construction

Because the panels themselves are very heavy, using special equipment is necessary when building a basement floor out of reinforced concrete. You’ll also need to hire workers and specialized equipment to clear the space for the base and foundation.

Items that may be required:

1. cement;
2. sand;
3. water – for preparing solutions.

Additionally helpful will be a concrete mixer, which will make installation easier. In order to insulate the base panels, you will also require a building level and a hydro- and vapor barrier.

Using reinforced concrete panels to build a basement gives homeowners a strong and long-lasting solution that offers superior structural integrity and moisture resistance. The speed and efficiency of this construction method are especially beneficial because the panels can be prefabricated and assembled on-site, saving money and labor. Furthermore, the superior insulation qualities of reinforced concrete panels contribute to the energy efficiency and comfort of the basement. Homeowners can make well-informed decisions regarding their basement construction projects by being aware of the special qualities and advantages of using reinforced concrete panels.

Step-by-step instructions for construction

The first step in any project is to clear the ground for the foundation. Once the space is prepared, the pre-selected foundation is built. If the concrete is strip or monolithic, you must wait for it to solidify after pouring before you can proceed with your work without interruption.

You can start work once the foundation has stabilized. The work consists of multiple stages:

1. Factory-produced panels are mounted on the finished foundation (it is also advisable to use a monolithic reinforced concrete slab). Since the panels are quite high, a crane must be used to lift them – order it in advance.
2. When installing basement panels, special attention is paid to the abutment nodes. Metal embedded parts, which are made in the form of thick cables, are installed at the factory for each slab. After installing the reinforced concrete panels on the foundation at an angle of 90 degrees, a cable and reinforcement with a diameter of 14 mm are inserted into them.
3. Then, along the seam, it is necessary to install formwork and fill it with concrete.
4. It is advisable to install the panels with a protrusion at the distance of the thickness of the insulation that will be used in the house. This is necessary to compare the thickness of the walls during their further construction.

It is possible to use foam to fill the spaces between the panels before adding insulation and sealing everything with a sealant.

Errors and difficulties of the process

If the owner is unaware that this procedure calls for the use of specialized equipment, problems may arise. Because the material is heavier than 100 kg per slab and is more than two meters high, installation with manual labor and auxiliary workers is not feasible.

Don’t forget about vapor and hydro-barriers as additional protective materials for slabs. The panel is exposed to aggressive factors over time, which can destroy it because it is in contact with the ground.

The best course of action would be to leave the construction to the professionals, as they are the most responsible and can potentially put the building in a dangerous emergency state that makes it unsafe for human habitation.

Pros and cons of using reinforced concrete and concrete slabs

When building a base, this building material has a number of benefits and drawbacks. Let’s start with the positive:

• resistance to temperature changes;
• resistance to aggressive external environments;
• fire resistance;
• excellent load-bearing capacity;
• strength;
• moisture resistance;
• long service life;
• high installation speed;
• good sound insulation;
• smooth surface, no finishing required;
• versatility of application.

However, there are drawbacks to this basement construction material, one of which is its weight. In this case, using construction equipment is necessary and will incur additional costs. The difficulty of fragmentary replacement is another drawback. It will not be feasible to replace the panel entirely if repairs are necessary.

Average price for construction

The price of a 3460x100x530 mm reinforced concrete panel for building a base starts at 1800 rubles on average. It is important to realize that purchasing a panel straight from the manufacturer will always result in a lower price than buying the item through retailers and middlemen.

Installing such a panel with specialized machinery starts at 3000 rubles per material unit. In the event that additional lintel installation is required on the solution, the cost per panel unit will start at 1500 rubles.

For many homeowners, constructing a basement with reinforced concrete panels is an economical and useful option. This technique ensures that your basement can withstand a variety of environmental stresses while maintaining strong structural integrity. When compared to conventional methods, the use of reinforced concrete panels expedites the construction process and facilitates a quicker completion of the project.

Because reinforced concrete panels are long-lasting, they require less upkeep over time. Because of their resistance to moisture, which is a common problem in basements, these panels can help avoid structural damage and mold growth. Their superior thermal qualities also help to improve insulation, keeping your basement warmer in the winter and cooler in the summer.

But when building a basement with reinforced concrete panels, it’s imperative to collaborate with skilled experts. In order to prevent problems like leaks or structural weaknesses, proper installation is essential. By selecting this building technique, you are making an investment in a sturdy, dependable basement that significantly increases the value and usability of your house.
