Building a brick garage is an investment in the safety of your car and the durability of the structure. Unlike metal hangars or sandwich panel structures, brick garage Provides excellent thermal insulation and corrosion protection. However, the construction process requires careful preparation, accurate calculations and compliance with building codes.
Before purchasing materials, it is necessary to develop a detailed design that takes into account the dimensions of the car, the presence of an inspection hole and the need for insulation. Red ceramic brick is a traditional choice due to its strength, but aerated concrete blocks or sand-lime bricks can also be used depending on the climate zone.
In this article we will analyze all the stages of creating a permanent garage, starting with choosing a location on the site and ending with installing the gate. You will learn how to properly mix the mortar, what type of foundation to choose for heaving soils, and how to avoid common mistakes when laying walls. A competent approach will allow you to build a structure that will last for decades without major repairs.
Site selection and structure design
Determining the location for a future building is a critically important stage that affects the ease of use and legal purity of the building. According to current standards, the garage must be located no closer than 1 meter from the border of the neighboring plot, and the distance to the windows of a residential building must be at least 6 meters. Violation of these rules may result in legal proceedings and demands for demolition of the structure.
When designing, it is necessary to take into account not only the area of the parking space, but also the space for maneuver, installation of shelving and a workbench. The standard size of a garage for one car is usually 4x6 meters, but for comfortable maintenance of the car it is better to increase the width to 5 meters. You should also immediately resolve the issue of electricity supply and availability inspection hole, since laying them after the construction of the walls will be impossible or extremely costly.
Design also includes choosing the type of roof. Most often, brick garages use a pitched roof with a slope towards the backyard, which simplifies drainage and reduces wind load. A gable roof is more aesthetically pleasing and allows you to organize an attic space for storing seasonal items, but requires a more complex rafter system. The slope of the slope must be at least 15 degrees for efficient removal of snow and water.
Calculation of materials and preparation of foundation
A brick garage has significant weight, so it requires a reliable foundation. For single-story structures, the optimal choice is strip foundation, which distributes the load along the entire perimeter of the walls. The depth of the tape should be below the freezing depth of the soil, which in central Russia is about 1.2–1.5 meters. The use of shallow foundations is possible only on non-heaving soils and subject to high-quality insulation of the perimeter.
To calculate the amount of brick, you need to know the thickness of the walls. Typically, garages are built with one and a half or two bricks (380 mm or 510 mm). A standard single brick has dimensions of 250x120x65 mm. When calculating, you should add about 10% for breaking and trimming, and also take into account that approximately 400 bricks and 0.25 cubic meters of mortar are consumed per 1 cubic meter of masonry.
☑️ Preparation for pouring the foundation
It is better to order ready-made concrete for the foundation, especially if the volume is large, since the continuity of pouring is critical for the solidity of the structure. If you prepare the solution yourself, use M400 or M500 cement in a 1:3 ratio with sand. The tape is reinforced with rods with a diameter of 10–12 mm, tied into a frame.
| Material | Unit of measurement | Consumption per 1 m³ of masonry | Note |
|---|---|---|---|
| Red solid brick | pcs. | 394 | Including 10 mm seams |
| Cement-sand mortar | m³ | 0.25 | Brand M75-M100 |
| Cement M400 | kg | 75 | In the solution |
| Construction sand | m³ | 0.22 | Coarse grain |
Wall masonry technology and reinforcement
Laying the walls begins only after the foundation has completely dried and waterproofing has been laid, which is usually used as roofing material or bitumen mastic. It is recommended to lay out the first row of bricks dry to check the size fit and distribute the cut elements. The solution is applied in a layer of about 2 cm, after which the brick is pressed and settled with a trowel, forming a seam 10 mm thick.
To ensure the strength of the structure, it is necessary to carry out masonry reinforcement. A wire mesh with a diameter of 3–5 mm is laid in every 4th or 5th row. This prevents the appearance of cracks during shrinkage and increases the resistance of the walls to loads. Pay special attention to corners and partitions - here the reinforcement should be reinforced.
Secrets of smooth masonry
To obtain perfectly even seams, use a template made from a reinforcement bar with a diameter of 10 mm, laid on the previous row. After laying the brick and removing excess mortar, the template is removed, leaving a neat groove for the next layer.
The height of the garage walls is usually 2.5–3 meters. When building walls, it is important to constantly monitor the verticality of the corners using a plumb line and the horizontality of the rows using a building level. If you plan to install sectional doors or a gate in the wall, it is necessary to lay metal embedded parts in advance or install reinforced frames during the laying process.
Floor and roof construction
Garage floors are often made of concrete slabs or cast-in-place concrete, but for self-construction a more affordable option is to use wooden beams or metal I-beams. The pitch of the beams depends on their cross-section and load, usually it is 0.8–1.0 meters. The space between the beams is covered with boards, on top of which a vapor barrier and insulation are laid.
The roof of the garage must reliably protect from precipitation. For a single-pitch structure, the rafters are laid with a slope created by different heights of opposite walls or special racks. A sheathing is mounted on top of the rafters, on which the roofing material is laid: corrugated sheets, slate or soft tiles. Corrugated sheet is the most popular choice due to its ease of installation and durability.
⚠️ Attention: When installing the roof, be sure to use a windproof film and provide a ventilation gap between the insulation and the roofing. Lack of ventilation will lead to the accumulation of condensation, wet insulation and rotting of wooden structures.
An important element is the drainage system. Even for a small garage, it is worthwhile to provide organized drainage so that water does not erode the foundation and create puddles at the entrance. The gutters are attached to the eaves, and the pipes drain the water into a drainage ditch or storage tank for technical use.
Gate installation and glazing
Gate installation is the final stage of box construction. Swinging metal gates, which are easy to manufacture and reliable in operation, are ideal for a brick garage. However, modern overhead sectional doors provide better thermal insulation and ease of use, although they require more complex installation and a smooth opening.
The gate frame must be rigidly fixed in the opening using anchor bolts or welded to the embedded parts. The gaps between the frame and the brickwork are carefully foamed with mounting foam and sealed with cement mortar. After installing the sashes, check the ease of movement and tightness of the seals.
Lubricate the gate hinges with graphite lubricant immediately after installation - this will prevent creaking and jamming of the mechanism in winter, ensuring smooth operation for many years.
If the project includes a window, its installation is also carried out during the construction of the walls or after the construction of the box. For a garage, a small window for natural light is sufficient, since the main function is performed by electric light. It is better to choose energy-saving double-glazed windows to minimize heat loss.
Interior decoration and communications
The interior of the garage requires protection from dust and moisture. The most common method of finishing walls is plastering with cement-sand mortar followed by whitewashing or painting. This creates a durable, washable coating that is resistant to mechanical damage. An alternative is cladding with tiles or PVC panels, but this is a more expensive option.
The floor in the garage experiences high loads, so a regular screed can quickly collapse. Recommended to use reinforced concrete screed at least 10 cm thick with the addition of fiber or metal mesh. To improve its performance properties, the surface can be coated with a topping or polymer composition, which will make the floor dust-free and resistant to fuel spills.
Electrification of the garage must be carried out in compliance with all fire safety standards. The wiring is laid in non-flammable corrugated pipes, sockets and switches are selected with a protection class of at least IP44. It is better to use combined lighting: general overhead light and local illumination of the work area.
What brand of concrete is best to use for a garage floor?
For the floor in a garage where a car is supposed to be parked, concrete grade M250 or M300 would be optimal. These grades provide sufficient compressive strength and wear resistance. If you plan to park a heavy SUV or use the garage as a workshop with heavy equipment, it is better to choose the M350 brand.
Is it necessary to insulate a brick garage from the inside?
Insulation is necessary if you plan to spend time in the garage in winter or want to prevent condensation from forming on the walls and car. Brick holds heat well, but without an additional layer of insulation (mineral wool, expanded polystyrene), the garage will cool down very quickly. Insulation also protects against the “thermos effect” in summer.
Is it possible to build a garage from used bricks?
You can use used bricks, but only after thoroughly cleaning the old mortar and checking for integrity. This material is suitable for internal partitions or outbuildings. For load-bearing walls and foundations, new brick is preferable, as it guarantees the declared strength and frost resistance.
High-quality foundation waterproofing and proper ventilation are key factors in the long service life of a brick garage, preventing dampness and structural destruction.
Building a DIY brick garage is a challenging but doable project for someone with basic construction skills. Compliance with technology, the use of quality materials and attention to detail will allow you to create a reliable shelter for your car. Do not rush to complete construction in one season - it is better to take breaks to gain strength in the mortar and concrete to ensure the durability of the structure.
