Building your own garage is not just about building walls, it is an investment in the safety of your car and personal space. Brick structures are rightfully considered the “gold standard” in garage construction due to their durability, fire safety and excellent thermal insulation. Unlike metal “shells” or lightweight foam blocks, brick garage able to withstand extreme weather conditions for decades, maintaining a stable microclimate inside.
However, the decision to build a brick garage with your own hands requires careful preparation, understanding of physical processes and strict adherence to masonry technology. Mistakes at the foundation laying stage or the wrong choice of solution can lead to cracks and dampness, which will negate all efforts. In this article we will analyze all stages of construction, from choosing a location to final finishing, so that you can create a reliable shelter for your car.
Design and selection of materials
Before purchasing the first batch of building materials, it is necessary to clearly define the parameters of the future structure. The standard size of a garage for one car is usually 4x6 meters, which allows you not only to place the car, but also to organize a work area with a workbench. It is important to immediately decide on the type of brick: solid brick is ideal for load-bearing walls. ceramic brick grade M-100 or M-150, which has high compressive strength.
You should not skimp on the quality of the base material, since the load-bearing capacity of the walls directly depends on this. If you are planning insulation, you can consider using hollow bricks, which have better thermal insulation properties, but require more careful handling of the mortar.
Also at the design stage, you should calculate the amount of necessary materials with a margin of about 10% for breaking and pruning. To lay walls one brick (250 mm) thick per 1 square meter, approximately 50-55 pieces of single brick are required. Do not forget to provide a place for a viewing hole or cellar, if this is included in your plans, as this significantly affects the design of the foundation.
- 🧱 Full-bodied ceramic brick - a classic for load-bearing walls and bases.
- 🏗️ Silicate brick is cheaper, but holds moisture worse and requires mandatory waterproofing.
- 🔥 Fireproof fireclay brick - necessary only if you plan to install a heating stove.
- 💧 Clinker brick is an expensive, but very durable and beautiful cladding that does not require plaster.
The choice of brick type should be based not only on budget, but also on the geological features of the site. If groundwater comes close to the surface, using silicate options can be risky without serious water protection. At the same time, ceramic bricks are more resistant to aggressive environments and temperature changes.
Laying a strong foundation
Brick walls have significant weight, so they require a powerful and stable foundation. Most often, a strip foundation is chosen for garages, which evenly distributes the load from the walls to the ground. The depth of the trench should be below the soil freezing level in your area, which is usually from 1 to 1.5 meters.
The process begins with marking the site and digging trenches for load-bearing walls. A sand and gravel cushion is poured onto the bottom and compacted thoroughly. Then the formwork is installed and the reinforcement cage is knitted, which gives the concrete the necessary bending strength. Concrete must be poured continuously to avoid the formation of “cold joints” that weaken the structure.
⚠️ Attention: Never start laying brick walls until the foundation concrete has gained full strength. This process usually takes 28 days, but in hot weather the time frame may be shorter and in cold weather it may be longer.
After the concrete has hardened, the upper part of the foundation (basement) must be protected from moisture. For this, bitumen mastic or rolled materials such as roofing felt are used. Lack of quality horizontal waterproofing will cause the brick to begin to draw moisture from the ground, which will cause dampness in the garage and destruction of the walls.
If the site has difficult soil or high water levels, it may be necessary to install a drainage system around the foundation. This is an additional cost, but it will ensure a dry room for many years. Ignoring this step can lead to flooding of the inspection hole and the appearance of mold.
Brick wall technology
The construction of walls is the most labor-intensive and critical stage of construction. The masonry is carried out with the obligatory bandaging of the seams so that the vertical joints of the rows do not coincide. This gives the wall solidity and stability. The solution is prepared from cement and sand in a ratio of 1:3 or 1:4, depending on the brand of cement and strength requirements.
The first row of bricks is laid on the waterproofing and carefully leveled. The geometry of the entire building depends on the quality of the layout of the first row. Each subsequent row is checked not only horizontally, but also vertically to avoid blockage of the walls. For corners, a template or special corner profiles are often used.
☑️Masonry quality control
It is important to maintain the thickness of the seam, which ideally should be 10-12 mm. A joint that is too thick reduces the strength of the masonry, while a joint that is too thin makes alignment difficult. The solution should be plastic, but not too liquid, so that the brick does not “float” under its own weight.
When building a garage, combined masonry is often used: the lower part (basement) is laid out in one and a half or two bricks for strength, and the main part of the walls is laid in one brick. If the garage is heated, you can immediately lay ducts for ventilation or a chimney using fireproof materials.
| Type of masonry | Wall thickness (cm) | Brick consumption (pcs/m²) | Application |
|---|---|---|---|
| Half a brick | 12 | 51 | Internal partitions |
| In one brick | 25 | 102 | Load-bearing garage walls |
| One and a half bricks | 38 | 153 | Basement, corners, cold regions |
| Two bricks | 51 | 204 | Very high loads, harsh climate |
Remember to leave openings for windows and doors by installing temporary lintels made from angle iron or concrete beams over the openings. The lintel must rest on the masonry at least 25 cm on each side of the opening. This will prevent the brick above the gate or window from collapsing.
Installation of jumpers and installation of armored belts
Above window and door openings, as well as under the Mauerlat for the roof, a reinforced belt or lintels are often required. This is especially true for garages with large spans or weak-bearing soils. The armored belt binds the structure into a single whole and prevents cracks from occurring during shrinkage.
To make lintels, you can use ready-made reinforced concrete products or make them yourself by pouring concrete into formwork with a reinforcement cage right on site. The key is to let the concrete dry completely before removing the supports. Hurry is unacceptable here, as the load on the jumper will be colossal.
If you are building a garage in a seismically active area or on heaving soils, installing an armored belt along the top of the walls is mandatory. It will evenly distribute the load from the roof and protect the walls from deformation. Under normal conditions, a high-quality brick row with reinforcing mesh is sufficient.
Do you need an armored belt for a small garage?
If the garage is small in size (up to 4x6 m) and stands on dense ground, a full armored belt can be replaced with reinforced masonry of the upper rows using reinforcing mesh every 3-4 rows. However, for structures with spans of more than 4 meters, an armored belt is required.
Roofing and ceilings for garage
The choice of roof for a brick garage depends on the budget and desires of the owner. The most popular are pitched roofs, which are simple to implement and provide good water drainage. A gable roof allows you to organize attic space for storing things, but requires a more complex rafter system.
For flooring, reinforced concrete slabs are often used, which are laid on the walls using a crane. This is a fast and reliable option that provides excellent heat and sound insulation. If a crane is not available, you can install wooden or metal beams followed by laying insulation and roofing material.
It is important to ensure reliable waterproofing of joints between slabs or beams. For this purpose, bitumen mastics and roofing felt are used. Insulation (mineral wool, expanded polystyrene) is laid on top of the waterproofing and a screed is poured or a roofing covering (slate, corrugated sheeting, soft roofing) is installed.
- 🏠 A pitched roof is an economical option, easy to install and maintain.
- 🏔️ Gable roof - aesthetic appearance and the ability to use the attic.
- 🚗 A flat roof that is in use is rare, but it is used as a terrace and requires complex waterproofing.
- 🌲 Wooden floors are cheaper than concrete, but require treatment against fire and rodents.
When choosing roofing material, consider the angle of the slope. For soft roofs, the angle should be minimal, and for slate or tiles it should be steeper so that snow and water do not linger on the surface. Correct installation of the roof will protect brick walls from waterlogging.
Insulation and interior finishing
Brick itself has good thermal insulation properties, but it is often not enough for comfortable use of the garage in winter. Wall insulation can be done both externally and internally. External insulation is preferable, as it shifts the dew point outward, preventing freezing of the walls and the formation of condensation inside.
For interior decoration, plaster is often used, which can then be painted or tiled. Plaster not only levels the walls, but also creates an additional protective layer. In unheated garages, finishing with corrugated sheets or OSB boards over insulation is popular, which creates a “thermos” effect.
⚠️ Attention: When insulating the garage from the inside, be sure to leave a ventilation gap between the insulation and the finish. This will prevent moisture accumulation and rotting of materials.
The garage floor also requires attention. Concrete screed is the most common option. To prevent it from generating dust, it can be coated with special polymer compounds, ceramic tiles or self-leveling flooring can be laid. This will make cleaning easier and extend the life of the base.
To quickly warm up the garage in winter, use foil insulation (penofol) on the walls. It reflects heat into the room, working like a thermos, which is especially effective for short visits.
Frequently asked questions (FAQ)
Is it necessary to reinforce each row of brickwork?
It is not necessary to reinforce each row. Typically, reinforcing mesh is laid every 4-6 rows of masonry, and also always under window and door openings and in places where structures support. This increases the tensile strength of the wall.
What mortar is best to use for laying a garage?
Cement-sand mortar grade M100 or M150 is considered optimal. The proportions depend on the brand of cement, but the classic ratio is 1 part cement to 3-4 parts sand. To increase plasticity, you can add lime or special additives.
Is it possible to build a brick garage in winter?
Construction is possible at temperatures down to -10...-15°C using anti-frost additives in the solution and heating water for mixing. However, the brick must be dry and not covered with snow or ice. It is ideal to carry out work in the warm season.
How long does it take for a brick wall to dry before finishing?
The brickwork must stand and “dry” for at least one season (preferably overwinter) so that natural shrinkage occurs and moisture evaporates from the mortar. Only after this is it recommended to apply plaster or insulation to avoid cracks.
