If you own a suburbanreal estate, then surely at least once thought about how to increase living space. There is not always the financial capacity and strength to acquire a new house or build it anew, the output could be an increase in the area of an existing building. For any such construction, the most important step is to create a quality foundation for the extension.
If you pondered the question of howto make a foundation for an extension to the house, then you should listen to the opinion of experts who advise to form the basis of the same construction as the foundation of the main building. This is due to the fact that different foundations can interact with the soil in their own way, which can cause different shrinkage. Therefore, do not save and build reliable identical foundations. Before you make the foundation for an extension to the house, you need to choose one of the three existing ways to connect the grounds. The first involves the formation of a monolithic foundation, which will be connected by metal thick reinforcement. The second method involves the construction of independent foundations, between which the expansion joint will be located. The third technology is a pile-screw foundation. Before pouring the base, it is necessary to take into account what the weight of the extension will be and what characteristics the soil has.
A solid foundation is great for building,which has been in operation for several years, and due to the uniform soil did not shrink. Otherwise, it is recommended to make a separate foundation, connecting it with the main one with the help of an expansion joint. Regardless of which method of creating the foundation was chosen, it should be deepened just as much as the foundation of the main house was deepened. Sometimes the foundation is slightly higher, given the shrinkage.
If you have a problem, how to doFoundation for the extension to the house, you can create a foundation on the hard reinforcement, which is suitable for an established house. Shrinkage of the latter at the time of the start of construction work must be completed. This design is not suitable for heaving soils.
Первоначально необходимо измерить глубину и dimensions of the old base, only after you can begin to prepare the trench. Its depth should not be greater than the depth of the foundation. In the old base holes are made with a diameter slightly larger compared with the diameter of the reinforcement. The depth of the holes should be determined by the following formula: for this, the diameter of the reinforcement should be multiplied by 35. If the base width is not enough for the hole, then the reinforcement should be hammered, for this, a longitudinal section is made at the end, and then wedging inserts are installed. This method of fixing the reinforcement is quite reliable.
If you are thinking about how to make a foundationfor an extension to the house from a brick, then the method described above perfectly will approach. To do this, calculate the number of rods. For a closed loop, a new construction most often requires about 20 elements per square meter of the foundation. Components are cut with an angle grinder or with an emery machine. If we are talking about an open loop, then the number of reinforcing bars can be determined individually, depending on the width of the future foundation. In the drilled holes should be installed rods, but before that at their ends are welded washers.
Quite often homeworkers are interested inhow to make a foundation for an extension to the house. An increase in the room will allow this. By the way of the above, it should be noted that further actions include the creation of formwork, which fit the fittings. The resulting space is filled with concrete. Then the solution is left until it is completely cured, after which the master can begin construction work.
Hard docking is used whenthe extension is united by a common roof with the main building, as well as in the presence of strip footings. This method of joining the bases is also used when the building is installed on a columnar foundation, and the attachment is carried out on the basement. This indicates that this element must have the necessary height and width. Rigid joining of two structural elements can be used in the presence of a shallow-depth strip-type basement, when it is included in one monolithic type system.
Перед тем как сделать фундамент для пристройки к the house from a bar, it is necessary to take into account that the construction of the separate basis is the most popular and simple way. In this case, the foundation will be located close enough to the main building, and a deformation joint should be installed between the structures. The function of the layer is to protect the structure from deformation and the formation of cracks during shrinkage. For the formation of a seam it is necessary to apply a moisture-resistant heat-insulating material, tow or roofing felt. Given that the design will still shrink, the foundation should be laid above the finished.
Если вы задумались о том, как сделать фундамент for an extension to the house, the photo is recommended to consider in advance. They will allow you to understand what technology is best to carry out the work. The gap between the new and the old base during the formation of a separate foundation should be 5 centimeters. Before concreting, boards covered with a waterproofing layer are applied to the finished foundation. In the future, these elements will play the role of a expansion joint. In the presence of a small extension in one floor there will be enough a seam, the thickness of which is 2 centimeters. Filling the resulting space can be done with insulating material, which often acts as a penoplex or foam. And you can close the gap with a sealant that is resistant to weathering. Outside, everything can be masked with a decorative overlay.
The foundation for the extension to the house from the blocks can be created using this technology, since it is the most acceptable.
If an extension is supposed to be formed fromlightweight materials like wood, the best option would be an inexpensive foundation on the pillars. If the dimensions are limited to 7x3 meters, it is enough to prepare 6 support pillars. It will be necessary to drill a hole in the soil, going deeper below the level of soil freezing. A sand cushion is laid on the bottom, fiberglass reinforcement is installed, and then the formwork of the required size is placed. The resulting hollow space should be poured concrete, and if necessary, increase the height of the supports you need to make a laying of red brick.
When professional builders think abouthow to make a foundation for an extension to the house, they most often resort to the method of forming the foundation on screw piles. This is because this design is the cheapest and easiest for non-heavy structures. As one minus appears susceptibility to corrosion, but this can be eliminated by the method of anti-corrosion treatment. Installation work will be carried out as soon as possible, after the completion of work it is permissible to proceed to further construction. For a small object, the supports can be screwed in independently, which will make it cheaper to work.
Before you make the foundation for an extension todo-it-yourself housework, you have to ask how the concrete is kneaded properly. The success of further work will depend on its quality. The darker the color of the cement, the more reliable and stronger the mixture will be. If you have not encountered the mixing process yet, then you should remember about the correct sequence of laying the components into the concrete mixer. Initially, the water goes, then crushed stone, sand and cement are laid further. Consistency must be observed in order to achieve a uniform composition. While all the components are mixed, the concrete mixer must be turned on, but during the rest of the motor of the equipment, you can measure the ingredients and bring them to the next batches.
If you have a question about how to dothe foundation for an extension to the house of the blocks, then you can use the above recommendations. They require the use of appropriate mechanical equipment for mixing the solution. This eliminates the formation of a seam between the cast layers.
