How to calculate a monolithic strip foundation: online calculator

Such a concept as "foundation" , denotes a house support. This is the lower structural part that will receive and evenly distribute the load. Its strength is the key to the reliability of the structure. A well-chosen size and thickness of the base will guarantee excellent performance and durability of the building. A calculator for calculating a monolithic foundation will help you here.

## Economic side

Unjustifiably overestimated foundation weights will lead to higher prices for work, and underestimation may be fraught with unforeseen consequences. The design challenge is to find a compromise between building costs and laying a solid foundation that can take the load from the mass.

Contributions to the start-up cycle are much greater when constructing small buildings than multi-storey buildings. When building brick houses, tape bases are often used.

It turns out that the technologies are used the same as in industrial construction.

As a result, in comparison with multi-storey buildings, the cost of 1 square meter increases significantly. It will be possible to reduce it with a competent choice of technology for arranging the base and its dimensions.

## Details

### What to choose

Stone and concrete bases can be divided into massive (they lie under the building), tape and pole (free-standing poles).

Columnar

Great for houses where there is no basements. Their advantage in comparison with the rest is efficiency.

But this type of foundation cannot be considered successful for buildings with a basement and a basement. Due to the danger of being pushed sideways by the soil pressure, they cannot be used in the presence of large altitude differences.

Ribbon

This is the most popular type when building private buildings. Their width will depend on how the ground withstands the load and on the volume at the base. An important advantage of the structures is that they carry it remarkably and have an excellent bearing capacity.

In the private sector, slightly deepened tape bases are used more often.

When laying them, prefabricated blocks, rubble stone or concrete monolith are used. For buildings with no basements, it is better to build prefabricated strip bases. The presence of a large number of joints between the parts needs to be waterproofed, and this will be a waste of labor and time.

Monolithic very laborious, but they form an ideal waterproofing, which is important when laying a house with a basement.

When building individual cottages, they are very economical and will cost 1.5 times less than prefabricated ones.

For the monolith, additional seam waterproofing is not needed, the labor capacity and expenditures at the initial stage are significantly reduced. In addition, the monolith is more stable when heaving in frost and soil subsidence.With increased soil moisture, waterproofing of the recessed parts is an obvious problem that can increase the cost.

The monolithic base is almost impervious to moisture, and with the addition of special additives, the cost will be lower than with the use of a specialized type of waterproofing.

Plated

Suitable for houses if the water index is too high in the ground ... According to the dimensions of the house, a single monolith is laid, which is reinforced with a frame.

By increasing the interaction of the base and foundation, the likelihood of soil subsidence decreases.

Reinforced concrete pile

The calculator for calculating a monolithic foundation will help when working. But reinforced concrete piles are lowered into the ground by means of vibrators. The piles pass through the upper, that is, looser soils and transfer the load to the denser layers. Deep layers begin to thicken, thereby increasing the degree of bearing capacity.

Bored

In fact, we are talking about wells that are laid with concrete and reinforced with a cage of reinforcement. In this case, the formwork is land that has been drilled to a depth of 1.5 meters and a width of 0.25 meters.

There are different types of bored piles, for example, those without additional reinforcement of holes for dry soil, rammed types of piles with overpressure strengthening for flooded and weak soils, as well as rammed piles with well strengthening casing pipes for fragile soil.

Screw piles

These are screws that are large and screwed into the ground. This type is suitable for buildings on weak soil with high waters, for quicksands. With this technology, earthworks are carried out.

### Bearing capacity

The first couple of years after the end of construction, the soil under the mass of the house begins to shrink. Under the influence of downpours and floods, the base subsides, thereby causing destruction and cracking.

The bearing capacity and dimensions are determined taking into account the soil characteristics and the width of the base. For example, a columnar base with a circumference of 0.25 meters will rest on 490 square centimeters of land.If the bearing capacity is 2.5 kg / cm2 (medium density sands), then the base can carry it (including and the thickness of the columnar base for building a house) up to 1.

225 tons.

A dense clay foundation of the same size can carry a load of 490 * 6 = 2. 94 tons. The base of the tape type (with a width of 0. 4 meters and a length of 0.

28 meters) with the dimensions of the base for a country house 6 * 8 square meters requires a base of 112,000 square centimeters. With the same bearing soil capacity, the foundation can accept the following loads: 112,000 * 2 = 22.4 tons, and 112,000 * 6 = 6. 72 tons. Such data are for dimensions about 1.

5 to 2 meters deep, with a base width of 0.5 to 1 square meter. As it deepens, the bearing capacity will increase. And at higher numbers, it decreases due to the lower soil density.

Pi calculating the width and capacity of the supporting type of base for the house, it is required to take it with a surcharge.

As practice has shown, this percentage is about 30. To create a safety margin, the load is increased. If the margin is made smaller, there may be a threat of subsidence (and even more so during the initial operational period) If you increase it, the cost of construction will become more expensive.

Loads on the base can be as follows:

• Types of roofs and their widths.

• Type and dimensions of roofing materials.
• Width and specifics of the overlap.
• Weight and size of building materials.

In any case, the calculator for calculating a monolithic foundation will be very useful to you.
