How to properly attach a garage to a house made of aerated concrete (an extension made of aerated concrete blocks to a wooden house)

One of the best ways to improve the usefulness and value of your home is to add a garage. If the garage extension uses aerated concrete blocks, as your house is built of this material, you must take certain precautions to guarantee a sturdy and safe attachment. The process of attaching a new garage to a wooden house will be covered in this guide.

Aerated concrete blocks are a common option in construction because of their low weight, excellent insulation, and simplicity of handling. However, because wood and aerated concrete have different properties, attaching them to a wooden structure requires careful planning and the right materials. You will gain an understanding of the best practices for creating a strong and seamless extension by reading this article.

It’s crucial to prepare a detailed plan and gather all required supplies before you begin. A thorough preparation will save time and avert future problems. Everything will be covered, including the building of the walls and foundation as well as making sure that the new and old structures are properly insulated and sealed.

You can make sure that your new garage blends in nicely with your current house and is both functional and attractive by adhering to these guidelines. Let’s examine the essential procedures and factors to take into account when joining an aerated concrete block garage to a wooden house.

To ensure structural integrity and seamless integration, attaching an aerated concrete block garage to a wooden house requires careful planning and execution. This procedure entails choosing the proper foundation, attaching the addition to the original wooden structure correctly, and applying the necessary sealing methods to stop moisture intrusion. These guidelines will help you build a sturdily constructed addition that adds value and functionality to your house.

Type of foundation

Selecting the appropriate foundation for the future structure is essential before adding a garage to an aerated concrete home. For various reasons, the foundation is typically built independently of the main foundation of a previously constructed home.

1. Absence of a section of the general foundation on which additional space could be placed. Rarely, when building a house, is the foundation poured for a future extension, since this is illogical: if an additional room is thought of immediately, it is included in the project and built on a common foundation, if not, then there is no point in a separate section of an empty foundation.
2. An extension to a house puts additional load on the foundation, which (provided that there was no additional room in the project and its weight was not included in the calculations) may simply not withstand it. Excess weight is a large load, distortions, subsidence, and other violations of the geometry of the structure may occur.

Building a separate foundation for the extension will be the most sensible and secure option in terms of the structure’s longevity and ability to function. Many factors are considered when choosing the type of foundation; the primary ones are listed below.

• Purpose of the premises – residential/non-residential, heated or not, what loads will affect the foundation (for example, if a storage room for inventory is planned, then small, if a garage for a large car – large).
• Area of ​​​​the additional room, height.
• Hydrogeological conditions of the site – type of soil, depth of groundwater, etc.d.
• Presence/absence of a cellar, basement under the building.
• Materials for construction and finishing, structural elements (for example, aerated concrete is lightweight and the extension will give a smaller load compared to brick, the type of roof and its weight, and other factors play a big role).

By accounting for each of these elements, you can determine the most appropriate option and determine the expected loads on the foundation with the highest degree of accuracy.

Possible types of foundation

Various foundation types allow for the possibility of adding an extension to the house. And while everything will work perfectly at first, design flaws usually become apparent when the building is put to use. For example, when the foundation shrinks, cracks start to appear all over the place, distortions start to show, etc.

It is definitely not worth cutting construction costs because of the inherent complexity of doing things correctly and the requirement to guarantee the maximum strength of the structure. Additionally, only objective considerations should go into choosing the foundation.

– appropriate for regions with elevated groundwater levels. Reliability and strength are provided by piling (or driving/screwing) the soil to the solid layers, but a basement is unavoidably absent. It is important to keep in mind that driving piles close to residential buildings can be hazardous; therefore, when selecting a pile foundation, manually screwing the piles in is the best option.

The soil type, the house owners, the territory’s capabilities, etc. are all taken into consideration when choosing a foundation. It is imperative to take into account the material used in the construction of the building. For instance, an aerated concrete extension bears significantly less load on the foundation than a wooden house, which is built of bricks. The variation in shrinkage may be significant.

For small extensions, a shallow strip foundation is typically used. Slabs are installed less frequently, but typically they form a base from pre-made reinforced concrete products placed on a sand and gravel mixture bed rather than creating monolithic slabs. There needs to be an access road to the building site close to the house because special equipment is used to lay the slabs.

Work procedure

You must thoroughly consider and prepare each action before granting an extension. It is advisable to create a project plan for the work that has to be done, get the necessary permits, and only then begin construction.

The completion of all paperwork can take some time, both in Moscow and in the regions, but building an unapproved structure without them can result in fines and other issues.

• First, carefully mark the site, mark the corners with pegs, pull cords between them. This will help to control the evenness of the trench for the foundation.
• Dig a trench, pour a sand and gravel mixture on its bottom in a layer 10-15 centimeters thick. This levels the bottom and creates drainage. Everything is carefully tamped.
• Next, the formwork is installed, its inner surface is lined with roofing felt, and the reinforcement frame is tied.

• The formwork is filled with concrete, the strip is kept until it reaches full strength (28 days).
• The formwork is dismantled, and they begin to build the walls. Aerated concrete is quite easy to work with and lightweight, it is laid on special glue in a staggered pattern (like brick). Aerated concrete is easy to process, so there should be no problems in construction. It is advisable to reinforce every 4th row by laying rods in grooves made along the wall.
• The walls are raised to the desired height, then tied with a Mauerlat, a rafter system is installed. Usually, the extension has a flat pitched roof (this makes it easier to install the rafters), the slope is directed away from the walls.

To ensure a stable and well-balanced addition, attaching an aerated concrete block garage to a wooden house requires careful planning and execution. Understanding the special qualities of each material will help you create a seamless, long-lasting join that enhances the current structure. Aerated concrete blocks are a fantastic option for an addition to a garage because they provide good fire and thermal resistance.

First things first, level a sturdy foundation in line with the house’s existing base. This action is essential to preserving structural integrity and averting further problems. Use specific connectors and techniques meant to account for the differing rates of expansion and contraction of concrete and wood to securely anchor the extension to the wooden house. This method guarantees a stable and secure attachment that is resistant to changing weather conditions.

To guarantee correct alignment and functionality, carefully consider where door and window openings should be placed when constructing the walls. To build a sturdy and long-lasting garage extension, use premium aerated concrete blocks and follow best construction practices. Remember to waterproof and insulate the intersection of the house and garage to preserve energy efficiency and avoid moisture issues.

Last but not least, adding finishing details like having the garage’s exterior match the house’s can improve the overall aesthetic appeal. Your new garage can be both a useful addition and an attractive addition to your house with careful planning and attention to detail.
