Laying the foundation for a frame house with your own hands: which is better? Review + Video Frame houses are lightweight structures that suit any type of foundation. There are two options for ways: to order analysis and design from a professional who will take soil samples, perform the necessary analysis, and then develop a house project taking into account individual parameters.

This will ensure that your support structure will faithfully serve for many years. The second way is easier and much more common - the experience of neighbors and their own knowledge. And we will try to help you choose the best type of foundation for a frame house, if you still chose the second way.

How to decide on the type of foundation

So, the choice of a foundation for any house, including a frame one, is very responsible step.

Laying the foundation for a frame house with your own hands: which is better? Review + Video For heavier buildings, for example, brick, it can be 30% of the total construction budget. But if you are building a light frame house, then the price of the foundation will be significantly lower.

Before deciding on the type of foundation, try to consider the following factors :

  1. Characteristics of the soil at the building site.
  2. The need for a basement.

  3. The total weight of the house - it should be calculated from the area of ​​the house and the material from which it will be built.
  4. The proximity of groundwater.
  5. Level of soil freezing.

Laying the foundation for a frame house with your own hands: which is better? Review + Video First of all, decide on the type of soil on the building site. To do this, dig a hole one and a half meters deep and study the cut of the soil: stony-sand, gravel without clay and coarse sand will be the best option.

They do not retain moisture, and they are not susceptible to frost heaving. Fine-grained and dusty sands are usually called heaving soils; this is not the best place for building a foundation. Soils with a high clay content, especially those with close groundwater, swell when freezing.

Now that we have figured out the type of soil with which we will be dealing, we can select the type of foundation.

It should be remembered: that the foundation should last as long as the house, therefore there is no need to make a reinforced concrete foundation for wooden and frame buildings.

Laying the foundation for a frame house with your own hands: which is better? Review + Video If the groundwater on your site is high, then there is no need to arrange basements. Even if you waterproof the foundation, there will still be high humidity there all the time. If you are planning to build your frame house on floating or loose soil, it will be better if you build a monolithic foundation. A shallow foundation will save money, and different types of foundations on sand cushions will also be inexpensive.

In light of the above, we can conclude that any of the low-budget and easy-to-use foundations can be suitable for the light construction of a frame house.

Types of foundations and stages of their construction

Now let's dwell in more detail on the construction of foundations for a frame house and consider the stages of construction.

Strip and strip-pile foundation

The most popular strip foundation . It has a low price and this type of foundation is easy to build. Some try to strengthen it with piles, in which case, it is called with a strip-pile foundation.

Laying the foundation for a frame house with your own hands: which is better? Review + Video Do-it-yourself strip foundation for a frame house requires scrupulousness and precise execution, since the slightest inaccuracy entails serious effects.

Such a foundation is usually made when the developer's plans include the presence of an insulated underground or basement. A shallow foundation fits perfectly on non-porous soils. But if you have a deep level of freezing, then either the trench will have to be made deeper, or reinforcement with piles twisted below the freezing level.

Laying the foundation for a frame house with your own hands: which is better? Review + Video First, markings are applied to the site corresponding to the facade and load-bearing walls - in the necessary places, poles are driven in, and a rope is pulled between them ..

. A second row of ropes is drawn to indicate the width of the walls.

According to this marking, we dig a trench 50-60 cm deep. If you reinforce it with piles, then more wells are drilled 20 cm below the freezing level. After that, pour a sand pillow and spill it properly with water.

The next step is erection of the formwork . First, we lay a waterproofing roll material on the side walls of the trench. On top of it, a formwork is made of cut boards 5 cm thick. All boards are placed vertically and must rise half a meter above the ground.

, in diameter. We connect with each other with knitting wire or welding. Get ready - this lesson will take you a long time, you can use an automatic pistol to speed up the process. Thanks to him, connections are spent 1-2 seconds.

After all, pour concrete.

For mortar, use cement at least M-500 with sand in a 1x3 ratio. Many people prepare the mixture on their own, but we advise you to buy a ready-made one. Pour the solution at a time, and use a special vibrator for compaction. We remove the formwork for 5-6 days.

Pile-screw foundation for a frame house

Laying the foundation for a frame house with your own hands: which is better? Review + Video The best option.

It is good on loose and unstable soils, in difficult terrain areas and areas with high groundwater levels. It has a lot of advantages : the foundation is installed without special equipment, it is mounted in just a day, high bearing capacity, resistant to soil freezing and the effects of groundwater, a lot of sizes and types, which makes it possible to choose the best option, low price, possibility carry out construction at any time of the year, it is convenient for the repair of an existing foundation.

Laying the foundation for a frame house with your own hands: which is better? Review + Video At the moment the market is full of various modifications of screw piles. The most important thing is that they have an even design and the correct shape of the blades.

Do-it-yourself installation of the pile-screw foundation takes place in two ways: manually or by contacting special equipment.

The second method is usually used when dealing with large diameter piles. For a light frame house, you can install them without assistance, but even in this case, you will need another 2-3 pairs of strong male hands. Thanks to the special design, the piles can be screwed manually, which allows you to more accurately set the horizontal level.

Laying the foundation for a frame house with your own hands: which is better? Review + Video Use steel screw piles with an anti-corrosion coating for your foundation at least 2.5 m, they do not enter the ground less than one and a half meters.

Before proceeding with the installation, you should mark the pile fields of the foundation and twist the piles along them. After twisting, the pile must be trimmed to the desired height and the trimming points must be filled with concrete. On top of the trunk we mount the head of the screw pile, on which, subsequently, we will mount the strapping. When the pile is roughened, the soil not only does not loosen, but, moreover, it is compacted by blades, which is a guarantee of the high bearing capacity of screw piles.

Column foundation for a frame house

Laying the foundation for a frame house with your own hands: which is better? Review + Video Represents a set of concrete pillars standing separately.

They are scattered around the perimeter of the house and at the joints of the walls inside it. Their lower part is usually called base , and the upper part - head . Watch the plane of the heads - it should be perfectly flat.

In most cases, they reach a height of 50-60 centimeters above the ground. Some of the pillars under the ground have a circular cross-section, and the above-ground ones are usually square.

Laying the foundation for a frame house with your own hands: which is better? Review + Video Wells for this type of foundation can be drilled with an ordinary garden drill. The diameter of the wells is calculated by the weight of the building and the additional safety factor. The pile should be supported on solid soil layers below the freezing level.

The depth of the well is approximately 2 m. The above-ground part is made of reinforced concrete, brick, wood.

But right away it is worth making a reservation that the service life of wooden piles is very short, even if they are treated with antiseptics and waterproofing.

Brick pillars are very time consuming - much better reinforced concrete. The pillars can not only have a regular cylindrical shape, but also expand at the base.

Monolithic (slab) foundation

It is a solid reinforced concrete slab that runs over the entire area of ​​the house. Among all types of foundations, this one has the highest bearing indicators, thanks to which it can provide high stability of the house on heaving soils.

The thickness of the monolith is from 10 cm, and at its base is a sand and gravel cushion, on top of which we put a layer of waterproofing.

Laying the foundation for a frame house with your own hands: which is better? Review + Video Above is a reinforcing frame made of two reinforcing meshes.The reinforcement in the slab should be ribbed with a diameter of 12-16 mm. , which will give the necessary adhesion to concrete. There should be a distance of 20 to 30 cm between the rods.

In addition, the slab requires a lot of concrete mortar, and will cost you more than any other type of foundation.

It is not necessary to make the slab smooth, you can add stiffeners, their location should be at the bottom of the slab and directed downward.

Due to the stiffeners, the slab will be prevented from deformation and movement in the horizontal plane.

Laying the foundation for a frame house with your own hands: which is better? Review + Video If your frame house will be without basements, then it is better to make a monolithic foundation shallow. First, remove the top fertile soil layer and lay geotextile instead.

Next, cover with a sandy pillow, compact with a vibrating plate and pour over with water. Now we need to put another layer of geotextile on top, pour gravel on top and tamp it again.
Laying the foundation for a frame house with your own hands: which is better? Review + Video Once everything is done, you need to assemble the formwork around the perimeter of the slab, and put the connected reinforcement inside. We pour concrete, remember that it must be of high quality. During pouring, we compact the mortar with a special vibrator on concrete to remove all air from our structure.

We wait 2-3 weeks for the foundation to fully harden, after which we dismantle the formwork and proceed to further construction. It is good to insulate the soil around the foundation to increase resistance to frosty baking. Building a house is a complex process and of course it is better to entrust it to the masters of their craft, a successful construction!
