How to build a garage with your own hands from cinder blocks?

Hands-on garage building can be a satisfying and economical endeavor. Constructing a garage with cinder blocks offers strength and durability that will last for many years. Even individuals with no prior construction experience can handle this process with the help of this guide.

Make sure you have everything planned out before you start. Take local building codes and regulations into consideration when choosing the location and size of your garage. Collect all required supplies, such as mortar, cinder blocks, and tools like a trowel, level, and measuring tape. You’ll save time and minimize possible problems during construction if you prepare properly.

When constructing your garage, the foundation is an important stage. The stability of the entire structure is guaranteed by a level and firm foundation. Take your time and get it done correctly whether you go with footings or a concrete slab. Once the foundation is in place, you can begin installing the cinder blocks, paying close attention to the layout to produce walls that are level and straight.

Consider small details like making sure the blocks are level and oriented correctly when constructing the walls. Consistency in mortar is essential for strong joints. Take your time; careful work and patience will produce a garage that is both aesthetically pleasing and more durable. Don’t forget to include door and window openings in your design.

The roof is installed after the walls are completed. You can choose between a more complicated pitched roof and a basic flat roof, depending on your preferences and level of skill. To protect against weather elements, make sure the roof is properly sealed and firmly fastened to the walls. The functionality of the garage will be improved by adding insulation and appropriate ventilation.

Installing the door, windows, and any other extra features you had in mind will complete your garage. This is your opportunity to make the area your own. These finishing touches, which could include workbenches, extra storage, or lighting, will make your garage useful and cozy.

Step Description
1. Planning Decide on the size and design of your garage. Get necessary permits.
2. Foundation Excavate the area and pour a concrete slab foundation.
3. Laying Cinder Blocks Start at the corners and build up the walls, using mortar to hold the blocks together.
4. Doors and Windows Leave openings for doors and windows as you build the walls.
5. Roof Install roof trusses and cover them with roofing material.
6. Finishing Install doors, windows, and any electrical wiring. Apply exterior and interior finishes.

Construction of a garage from cinder blocks

The following varieties of cinder blocks can be used to build a garage on your own:

  • solid. They have increased strength, are used to build a foundation. Disadvantage – a reduced degree of thermal insulation and increased weight;
  • hollow. They are distinguished by their low weight, increased thermal insulation characteristics. Allow you to easily erect the walls of the building. They are inferior in safety margin to solid products.

Although there are many different types of slag, blast furnace slag is the one with all the necessary properties for construction.

Properties of the material:

  1. Specific gravity 0.75–1.45 t/m3. Allows you to easily carry and quickly lay the blocks.
  2. Thermal conductivity 0.25–0.7 W/m3. Ensure a comfortable room temperature.
  3. Dimensions – 18.8 x 19.9 x 39.9 cm. Allow for quick construction.

Take note! The material’s low cost, larger dimensions, and decreased requirement for cement mortar all contribute to lowering the projected cost of construction.

After discussing the material’s characteristics, let’s talk about where to begin construction work:

  • conduct geodetic studies of the soil at the work site;
  • determine the distance to electrical communications and water supply lines;
  • decide what kind of garage is better to build – a two-story, an enlarged 4 by 8 or a room for 2 cars;
  • design the garage taking into account all the features;
  • decide which method to use to lay the blocks, determine the amount of material, study the step-by-step instructions;
  • calculate the estimated cost of work, taking into account all expense items and features of a building consisting of one or two floors.

Before constructing a garage, the necessary steps must be finished, a building permit must be obtained, and the necessary number of blocks must be purchased.

Now let’s think about building a garage. The following categories of work are included in the overall set of activities:

  • Preparation of the construction site. The developed plan is transferred to the site using a cord, tape measure and wooden pegs. The marking is preceded by the removal of vegetation and site planning.
  • Construction of the foundation. A strip foundation can be used for a garage building. To do this, you need to remove the soil to the depth specified by the project, plan the foundation, align the pit walls, install the formwork with reinforcement, pour concrete to the base level.
  • Arrangement of effective waterproofing. It is important to reliably protect cinder block walls from moisture absorption. Using rolled roofing felt laid in two layers on the foundation of the building, a waterproofing layer is formed.
  • Erection of walls. Standard masonry with half-length overlap of blocks is used. In this case, the construction of the walls of the room begins with the corner parts of the building along a pre-stretched cord. Horizontal control is performed with a building level.
  • Installation of pre-primed gates and doors, if the doors are provided for by the project requirements. Installation of the gate frame simultaneously with the construction of the walls allows you to reliably fix the structure in the cinder concrete masonry using embedded elements.

Low thermal conductivity and light weight are characteristics of cinder blocks with high friction, while lower friction cinder blocks are weaker.

  • Device of the ceiling structure and installation of roofing material. A reinforced concrete slab located under the slope of the garage can be used as a roof of the garage room or a lightweight gable roof is made with slate, tiles or corrugated board.
  • Filling the floor and blind. Paul concreting is carried out on a gravel-sand pillow with a concrete solution of the brand M200. The thickness of the screed layer of 100 mm, poured continuously, will ensure the integrity of the base that perceives the mass of the car. A blind area with a thickness of 50 mm is performed with a slope that ensures water drainage.
  • Connection of engineering communications. The energy supply supply to the garage room will increase the degree of comfort and will allow you to connect lighting, and it is also necessary for repair and maintenance electric equipment. The supply of waterways is also useful.
  • Finish and reliable insulation. The traditional type of decoration is cement plaster and white whitewashing. To ensure a comfortable thermal regime, you can use foam sheets or fiberglass, followed by the installation of plasterboard sheets inside the room.
  • Ventilation system device. Ensuring air circulation will ensure a comfortable level of humidity, remove carbon monoxide gases outside the garage. The best solution is to install a supply ventilation system.

Crucial! Remember that cinder blocks can become damp from excessive humidity. Dry soils are required for construction, and the blocks need to be carefully shielded from moisture intrusion.

How much cinder block is needed for a garage – calculation method

It is simple to determine on your own how much material a garage needs to be built. To complete the computation, get ready:

  • a piece of paper;
  • a pen or pencil;
  • a calculator.

Let’s figure out how much material is needed to construct a garage that is six by six meters and 2.4 meters high:

  1. Determine the perimeter of the building: (6 + 6) x 2 = 24 meters.
  2. Calculate the surface area of ​​the walls, multiply the resulting value by the height of the building: 24 x 2.4 = 57.6 m2.
  3. Calculate the area of ​​the walls without the entrance gate: 57.6 – (2.2×3) = 51 m2.
  4. Determine the area of ​​the side surface of the block for the edge laying option: 0.399×0.188=0.075 m2.
  5. Calculate the number of blocks per square meter of the building area: 1:0.075=13.3 and round the value to 14.
  6. Multiply the area of ​​the walls by the number of products per square meter: 51×14=714 blocks.

Take note! It is advisable to buy more material in order to account for potential flaws and damage to the products’ integrity during laying and transportation.

Constructing a garage by hand using cinder blocks is a doable and satisfying project that blends durability and functionality. This tutorial will take you through all the necessary steps, from building the walls and installing the roof to laying a strong foundation. By using simple tools, planning ahead, and a little perseverance, you can build a durable structure that fulfills your requirements and increases the value of your home. Whether you’re a novice or a seasoned do-it-yourselfer, this simple method guarantees you can finish the project successfully and experience the joy of building your own garage.

Development of a cinder block garage project

The foundation for carrying out construction activities is the critical stage of work, which is designing a room for storing a vehicle. The design stage can be approached in a variety of ways:

  • develop a project yourself. This is a budget solution that does not require any financial costs;
  • use the services of professional designers. On a contractual basis, professionals can develop the necessary drawings and detail individual units;
  • adapt a standard project. Using a ready-made plan and standard drawing, you can independently choose the layout of the future building.

To select your own design option, it is advised that you look at drawings or pictures of completed garages before beginning construction.

The following decisions must be made during the design phase:

  • purpose of the garage. Depending on whether it will only be used to store the vehicle or to carry out repairs, the dimensions change;
  • the need to arrange an inspection pit. The depth of the pit should ensure the ability to comfortably carry out repair work;
  • the feasibility of placing a cellar for storing food and canning. Combining two functional rooms within a common structure is very convenient.

Take note! Most passenger cars can be parked in a garage that is 3 by 6 meters with a room height of 2.5 to 2.8 meters.

With the vehicle’s dimensions in hand, figuring out the room’s measurements to accommodate comfortable movement and the positioning of the required racks and shelves is simple:

  • 1.4–1.6 m should be added to the length of the car;
  • add 1.8–2.2 m to the width of the car.

Constructing a garage by hand using cinder blocks is a satisfying and doable project. You can build a sturdy and useful space for your cars and storage needs by carefully planning and following the instructions. The first steps in the process involve choosing the ideal site and making sure the foundation is strong, both of which are essential to the stability of your building.

Next, accuracy and perseverance are needed when assembling the walls using cinder blocks. Straight and even walls can be maintained with the use of string lines and a level. Take your time, as it will yield the best results, and don’t rush this step. As you construct the walls, don’t forget to leave gaps for windows and doors. For added strength, reinforce the walls with rebar and fill the cores with concrete.

The last major task is to install the roof after the walls are up. You may choose for a more intricate pitched roof or a straightforward flat roof, depending on your design. Regardless of the option you select, make sure it is firmly fixed to the walls and offers sufficient weather protection. Enhancing the garage’s insulation and ventilation will further improve its year-round comfort and functionality.

Lastly, adding finishing details to your garage can increase its usability and aesthetic appeal. These include painting, adding doors and windows, and installing electrical wiring. The satisfaction of finishing a garage with your own hands makes the effort and attention to detail required for this project worthwhile. You can build a long-lasting addition to your home with some careful planning, the appropriate supplies, and a little perseverance.
