Dimensions, markings, assortment and weight of FL foundation pads

To increase the load-bearing capacity, strip foundations are usually made with a widening at the bottom. In this case, the weight of the building is distributed over a larger area, and the base better bears the load. When making the supporting part of a building from precast reinforced concrete, it is customary to use FL foundation pads as the lower part.

What types of FL pillows are there?

Fundamental elements differ in two ways:

• load bearing capacity;
• sizes.

There are 4 groups according to load-bearing capacity. Which group a certain pillow belongs to must be indicated in the labeling. The higher the number, the greater the load the structure can withstand.

FL foundation pillows are available in several sizes. All parameters vary: length, width, height. The sizes of slabs produced according to the assortment can be seen in the table. The product markings and their weight are also shown here .

Advice! Before purchasing structures, it is recommended to draw a diagram of their location around the perimeter of the building and under the internal walls. In this case, it is necessary to take into account the dimensions of the elements. Such preliminary work will allow you to optimize costs and calculate in advance how many FL foundation slabs will be required and what sizes. The weight of the pillows is also important. Knowing it in advance, you can calculate transport costs.

Quality control

Strength characteristics are determined by both destructive and non-destructive testing methods, which involve the use of ultrasonic testing, mechanical instruments, and special laboratory equipment. The corresponding section of the standard contains references to regulatory documents, according to the requirements of which the characteristics are controlled:

• compressive strength;
• frost resistance;
• water absorption;
• waterproof;
• integrity of welded joints;
• position of embedded elements and reinforcement;
• geometric parameters;
• tolerances;
• surface quality;
• the size of the opening of shrinkage gaps;
• appearance;
• thickness of the protective layer.

How to fill the foundation inside: choice of material

At the beginning of construction, land owners are interested in the question of arranging the foundation. Does it need to be backfilled from the inside, what materials are used to carry out the work, and what influences the choice of bulk materials.

When performing work on a pile foundation, it is necessary to take into account secondary features.

In order to finally decide on the selection of material and the thickness of the fill, you should find out at what level the groundwater is located, how much the soil can subsidence and the financial condition of the owner.

It’s also a good idea to think about what is more profitable financially:

• backfilling for the foundation when using bulk materials;
• built basement with ventilation and high-quality thermal insulation of the flooring.

Materials used for internal backfill

An excavator is most often used to dig a hole for the foundation. The construction project is the main document. Therefore, when digging a recess, checking with it is necessary. It has calculations based on the volume of excavated soil.

The pit should first be sprinkled with sand, the thickness of which should be no more than fifteen centimeters. The sand coating is well leveled and compacted.

In order not to make a mistake in choosing the best way to fill the internal foundation, special attention should be paid to the type of soil. Construction soils are divided into the following types:

• black soil, which is not used for backfilling inside the foundation;
• loam;
• rocky soil;
• clay;
• crushed stone

Clay and loam have the most benefits. They are characterized by excellent waterproofing and can resist impact loads. It is not recommended to use clay with other impurities. Because it loses its waterproofing qualities.

The inside of the foundation is sprinkled with it, no more than thirty centimeters. We should not forget about the intensive compaction that must be performed when backfilling. This helps eliminate air sinuses. Mixed gravel and sand are not used for pile foundations.

Good raw materials for backfilling the foundation are sand and crushed stone. Coming into contact with water, their qualities do not change. The sand compacts well with periodic watering. After this, backfilling is carried out to balance the pressure on the foundation.

It is carried out evenly throughout the entire part of the future home.

Internal backfill for screed

Very often the basement is not usable. Owners whose plots are located on marshy soils fall into this category. Then backfilling is done inside under the screed. The materials used for the work are the same. Clay is one of the best ways to base a screed.

It is laid and compacted to a thickness of thirty centimeters. The clay embankment provides complete protection from groundwater. The next ball is filled with sand, which must be compacted and well soaked with water. After this, it is necessary to waterproof it using roofing material.

Foam is laid on top to form a heat-insulating layer, or sand is poured to form a concrete screed.

In addition to these actions, other work is carried out to provide additional waterproofing. In particular, drainage is installed, the basement is waterproofed, and blind areas are made throughout the entire territory of the house.

External backfilling of the foundation

The external foundation can quickly succumb to swelling due to the fact that its edges are not protected from the cold. The ground freezes and begins to pull out concrete structures. To avoid this, it is also necessary to sprinkle the foundation from the outside. This problem can be solved using the following methods:

• When backfilling, the foundation sinuses are filled with non-metallic materials: a sand or crushed stone shell of at least twenty centimeters;
• the blind area is insulated;
• Thermal insulation is performed using polystyrene foam, polyethylene film, and PSB sheets.

The main layer of thermal insulation is not damaged due to soft polystyrene. In the spring, the structural elements return to their original state after the soil volume decreases. Sand and crushed stone are used as materials for sprinkling the outer part.

Normal operation requires a certain density of the shell, so backfilling is done in layers and must be compacted. The sand does not need to be watered so that there is no danger of washing out the lower layers. It is moisturized before styling.

In case of high groundwater levels, it is recommended to use crushed stone.

Scope and main characteristics

The main document regulating the production, acceptance and use of FL foundation cushions is GOST 13580-85 (hereinafter referred to as GOST). When designing a building, it is necessary to take into account some restrictions on the use of elements. These restrictions are discussed in the regulatory document:

• design temperature of outside air is less than -40°C (value is taken according to SP 131.13330.2012);
• the calculated seismicity of the construction area is more than 9 points;
• underground water or soil contains chemicals that can destroy concrete.

Important! The use of pillows at estimated negative temperatures below 40°C is permissible, but only if additional measures are taken to protect them.

FL pillows manufactured according to GOST have a trapezoidal cross-section. The upper, narrower part is intended to support the foundation walls (for example, made of FBS blocks). When installing blocks on a foundation slab, it is recommended to ensure that the vertical seams are tied. The minimum displacement of elements relative to each other is 250 mm.

When purchasing products from a factory, it is worth checking their compliance with the requirements. These requirements are given in GOST:

1. concrete class of slabs FL is not lower than B10, maximum - B25;
2. reinforcing mesh is made of steel of classes A400 (A III) and BpI;
3. the product has mounting loops, which are located in accordance with GOST;
4. deviations from the dimensions indicated in the assortment do not exceed 5-10 mm;
5. When shipped from the factory, the concrete managed to gain at least 70% of its brand strength.

It is also worth considering the load-bearing capacity of the products. The exact value should be checked with the manufacturer. It is important that the pressure from all house structures does not exceed the design pressure.

What is stated in the regulations?

GOST sets out the requirements according to the points:

• scope of application;
• temperature regime;
• design parameters;
• dimensions;
• level of permissible seismicity;
• installation of fittings;
• designation of the plate, its marking;
• technical features;
• reception technique;
• quality control methods;
• delivery, storage, preservation.

According to the regulatory document, foundation slabs with the designation “FL” are used for foundations and foundations of strip structures that are located below the lake. The main purpose is to expand the base by increasing the width of the foundation support.

The slabs can be used in dry soils, as well as in wet rocks, where there are no aggressive components that can affect reinforced concrete structures.

The standard specifies the operating temperature range of products, as well as the level of seismic loads perceived and tolerated without damage:

• the slabs can be used in climates where the external temperature does not fall below -400C;
• products can be subject to seismic forces up to 9 b.

The products can be used at low temperatures, but they must be previously discussed with the manufacturer when ordering production. There are other building codes for this.

Acceptance specifics

Finished products at the enterprise are accepted in batches not exceeding 200 pieces in volume. Tests are required to monitor the moisture resistance, frost resistance and water absorption of the composition. Using control data, the strength of concrete, welded joints, and dimensional accuracy are checked.

Sample control is used when checking:

• accuracy;
• crack opening width;
• surface categories.

The presence of mounting loops, embedded elements, and correct markings is checked using a visual method.

To test mounting brackets, a sample of three products is taken, which is subjected to 5 lifting cycles followed by visual inspection. In the area where the hinges are installed there should be no signs of damage to their integrity.

Design Features

The standard provides for the installation of fasteners and steel rods, taking into account the provisions of the project, on the object or structure being built.

To move the slabs, rigging devices are used, the design of which is specified by the supplier and agreed upon with the designer and the customer. The products can have special holes for loopless installation, taking into account the design features of the lifting device.

The regulatory document allows products to be equipped with hinges for installation, the installation diagram of which contains a mandatory appendix to the standard.

Depending on the weight of the product, from two to four hinges are installed (one of six possible installation options). The material requirement for each bracket is provided for by the standard under consideration.
