Purpose, types, step-by-step instructions for arranging a garage blind area with your own hands

To shield your garage’s foundation from moisture and soil erosion, you must create a garage blind area. This space, which is sometimes called a "perimeter or apron," fulfills a number of vital functions. First of all, it aids in deflecting rainfall away from the garage’s base, avoiding water seeping into the foundation and gradually causing damage.

Garage blind areas come in a variety of forms, from straightforward gravel or crushed stone beds to more intricate concrete or paver installations. Aesthetic preferences, budget, and weather all play a role in the decision. Whatever style is selected, setting up a garage blind area can be accomplished successfully by following a methodical process.

Examine the dimensions and layout of the area surrounding your garage where the blind will be installed before proceeding. To make sure there is enough coverage, measure outward from the garage walls, usually measuring past the roof’s drip line. To create a smooth base, remove any plants, debris, and uneven surfaces from the area.

Next, ascertain the required materials according to the kind of blind area you have selected. You’ll need landscape fabric to keep weeds out of the gravel or crushed stone bed, as well as a layer of appropriate aggregate. If you decide to use pavers or concrete, gather the equipment you’ll need, including a wheelbarrow, shovel, level, and masonry or concrete mix. To ensure durability, make sure all materials are of the highest caliber.

After everything is ready, begin by erecting the forms or edge restraints around the blind area’s edge. Depending on the design and materials utilized, these can be constructed out of metal, plastic, or wood. Over time, the edge restraints will help keep the material contained and the blind area’s shape.

What is?

Actually, the blind area is composed of layers of materials that are resistant to moisture, angled away from the garage. The top is covered with a weather-resistant coating, which allows water to run off and into the storm drain.

In terms of the garage, there are two choices:

1. Around. This is a continuous path along the entire perimeter of the building.
2. Before entering the box. Protection is installed in a limited area in front of the threshold.

When excavating a trench around a buried blind area, the area is ready—marks are made, drainage is planned, and the walls are raised by two thirds of their eventual height. After construction is finished, installation of a limited design option can start.

Why is it needed??

Blind areas surrounding the car box’s primary functions:

1. Water drainage. After precipitation falls, it rolls down the wall and drain onto the blind area. Due to the slope and with the help of a storm drain, they are diverted from the building to a safe distance and drained into the collector. The base of the building does not get wet, building materials do not collapse. The foundation, plinth and walls are preserved from cracks and destruction.
2. Thermal insulation. The moisture in the soil freezes with the onset of cold weather. This process stimulates its increase in size, as a result the earth begins to move and put pressure on the walls of the building. The process takes place along the entire perimeter at the same time and the base of the structure begins to shift, cracks and warps. This phenomenon is called soil heaving. The blind area, regardless of the degree of depth, becomes an obstacle to freezing. The base remains intact, the basements and basement retain heat better. Saves resources on heating your home.
3. A protective strip from the roots of trees and shrubs prevents the appearance of microorganisms that can damage the foundation building materials.
4. Completed aesthetic appearance of the building.

If the blind area is situated in front of the garage, there are additional advantages:

• helps to maintain a flat surface at swing gates, the soil does not swell or deform, the doors always open easily and do not get stuck;
• a convenient entry into the box is formed, an easy lift helps to cross the threshold without harm to the car.

Establishing a capable drainage system is essential to preserving complete functionality.

Varieties

You must determine the depth of the blind area’s penetration into the ground before beginning construction. Experts concentrate on how deep to lay the foundation:

1. Superficial. Protects weaker than others; a trench is dug 20-30 cm deep into the ground.
2. In-depth. Suitable for garages with foundations and basements. The standard thickness option is half the soil freezing level. A trench in central Russia is dug at 40-50 cm.

The amount of groundwater passage has an impact on the blind area’s height as well. Rarely is the trench dug deeper than 40 cm when constructing an independent garage; this is because the level is rarely reached.

Around the building

The level of protection and surface type in these designs vary. Potential choices:

1. Rigid, monolithic. The final coating consists of concrete, asphalt, or is additionally covered with facing materials (paving slabs or paving stones). Reliable, multi-layer construction, depth up to 50 cm. It retains heat as much as possible, suitable if the garage has a repair pit, ground floor or basement. Externally it looks like a path, the width should be 20 cm greater than the level of the roof overhang. If desired, you can use it to create a ground parking space or a recreation area if you increase the coverage area. Pros: warmth, reliable protection from moisture, durability. Cons: labor-intensive installation process, high consumption of materials.
2. Soft, bulk. The coating here is made of crushed stone, gravel or granite chips. The option of laying a lawn is possible, but before entering the box it is better to use solid material. Such a blind area is deepened by a maximum of 30 cm and consists of fewer layers. Advantages: easy to do it yourself, budget-friendly. Disadvantages: the car can slip, maintenance is required, a thin layer for northern regions.

In any event, to prevent a puddle from forming at the base of the blind area, a slope away from the garage wall is required.

Before the entrance, gate

In this instance, the structure is arranged in front of the garage door because there are other rooms that it is walled in front of.

1. Monolithic rigid structure. Built on the same principle as around a garage. The main thing is to maintain the slope from the entry threshold. The width of the blind area here depends on the convenience of the owner. The optimal size is considered to be up to 1-1.5 meters; you can extend it to the length of the car or make a spacious area in front of the entrance with several parking spaces. Paving slabs and paving stones are used for covering. It is not recommended to leave “bare” concrete, since under the weight of vehicles it will quickly become cracked and collapse.
2. Soft design. Such a blind area is deepened by 20-30 cm, the top layer is gravel, crushed stone. For a more stable coating, you can use a thin layer of cement and cobblestones, it is heavier and it will be easier for a car to drive over it.

To allow the car to easily climb up and take its place, the highest point of the blind area in front of the garage should be level with the box’s threshold. A slope is used to provide free movement for swing gates.

Consumables and tools for construction

Tools required to create a blind area:

• shovel;
• vibrator (not necessary, but desirable);
• pegs, cord;
• boards for formwork and partitions;
• building level;
• rule;
• Master OK;
• putty knife;
• container for mixture or concrete mixer;
• metal scissors, knife.

Resources:

• sand;
• clay;
• crushed stone;
• concrete mixture;
• water;
• paving slabs/paving stones;
• waterproofing material (for example, roofing felt);
• geotextiles;
• mesh made of reinforcement (10*10);
• chemicals for impregnating soil from microorganisms;
• thermal insulation material (optional).

The kind of future blind area determines the different tools and materials needed.

How to do it yourself?

Setting up a blind area in front of the garage: Sequencing

1. Dig a rectangular hole close to the threshold of the garage. Decide on the width in advance, minimum 1 m, usually more, so that the car can easily park next to the gate. Depth 40 cm.
2. Next, the “pie” is assembled according to the same principle as around the garage. Layer of clay, wet sand, waterproofing, crushed stone. All with a slope away from entering the box.
3. Formwork, reinforced mesh and dividing boards are installed. The boards are placed in a square, the side of the sector is 50-70 cm. The first layer of screed is poured in stages, into each cell, leveled at an angle. Afterwards you need to wait until it dries completely.
4. The final layer is made thinner, and paving slabs are laid out step by step.

The blind area’s ends should be flush with the box’s threshold, and its beginnings should be nearly flush with the ground. Sand is sprinkled on elastic material that is positioned between the protective layer and the garage entrance, leaving a gap of two to three centimeters. To drain water at an angle toward the collector, gutters are installed around the perimeter.

Paving slabs, curb stones, and concrete are used to reinforce the sides. Concrete has a 30-year lifespan if ironing, reinforcement, and technology are used properly. Their lifespan is extended to 50 years by paving slabs.

Setting up a blind zone around the garage through sequencing:

1. Dig a trench. Depth 40 cm, width approximately 1 m (depending on the level of the roof overhang) and soil quality. If the soil is loose, heaving, then at least 1 m.
2. Treat the bottom with a chemical composition against microorganisms. Lay a layer of clay 10 cm wide, compact it thoroughly (it is advisable to use a vibrator, but not necessary). From the moment of laying the first layer of the “pie” of the blind area, it is necessary to maintain a slope from the wall with the calculation of 2-3 cm per 1 m of covering width.
3. Lay a thin layer of wet sand up to 10 cm thick on top.
4. Lay roofing material or moisture-proof film in overlapping layers. The waterproofing should extend approximately 20 cm onto the foundation wall, additionally protecting it from moisture.
5. Fill in a layer of crushed stone, height 15-20 cm, level.
6. Assemble formwork around the perimeter of the blind area, height 5 cm. Between the foundation wall and the blind area it is necessary to leave a distance of 2-3 for potential shrinkage of structures. Afterwards, insulation or roofing felt is placed in the opening and covered with sand.
7. Reinforced mesh is laid at the bottom of the trench. On top of it, across the trench, dividing boards in 2-meter increments will create the seams necessary for uniform distribution of concrete.
8. Prepare the concrete in portions, pour a 10 cm layer into each compartment individually, level it according to the rule, maintaining the slope from the foundation wall.
9. After leaving to dry, periodically moisten with water to prevent cracking.
10. Place the finishing layer on the completely dry and primed first layer, fill it and at the same time level it with the rule, maintaining the slope.
11. Iron the surface using cement. Cover with film, leave to dry completely, moisten with water periodically.

In the event that you choose to tile the blind area, you should do so prior to the last concrete layer drying; otherwise, the layer will be thinner.

Possible mistakes

What might not work well:

• the size is narrower than the roof overhang – the blind area will not function correctly, you need to initially calculate the width correctly;
• there is no storm drainage system, there is no drainage – installation of the drainage system can be done after laying the blind area, the storm drainage system can be partially laid on top of the covering, the rest along the perimeter;
• stagnant water appears, which means that the required slope has not been maintained, dismantling and re-installation is necessary, otherwise there is no point in the design;
• the concrete is covered with cracks – this happens if the concrete laying technology is not followed (there were no distribution joints, the layer did not have time to dry, the material was not wetted, etc.).), the service life of such a blind area is reduced.

Every step needs to be watched closely, particularly if inexperienced builders are working to create the blind area. If not, the outcome will be catastrophic and the foundation will collapse much more quickly.
