Using the proper concrete composition in a blind area is essential for safeguarding the foundation of your home. In addition to improving the aesthetics of your home, a well-constructed blind area keeps water from penetrating the foundation, which could cause major structural problems. Correct concrete mixing, which ensures the proper proportions of materials for maximum strength and durability, is essential to a successful blind area.
Using buckets to measure the ingredients is one of the easiest ways to mix concrete. This technique guarantees a robust and long-lasting mixture by enabling accurate and consistent proportioning. Concrete usually consists of four main ingredients: cement, sand, gravel, and water. To attain the ideal ratio of strength to workability, precise measurement is crucial.
One part cement, three parts sand, and three parts gravel is the recommended ratio for a standard concrete mix for a blind area. The mixture is gradually thinned out until the desired consistency is reached. For do-it-yourselfers in particular, the process is made simpler by using buckets as measuring tools because they do not require scales or intricate calculations.
Making the concrete mix by hand can be a satisfying endeavor. You save money on labor expenses in addition to gaining a deeper understanding of the components and procedure. It is possible to build a dependable blind area that will safeguard the foundation of your house for many years with a few basic tools and some perseverance. By adhering to these recommendations and using the appropriate ratios, you can make sure that your concrete mixture is robust and long-lasting, offering superior resistance to water damage.

Design Features
The covering that completely encloses the building is known as the blind area. possesses a defined, continuous width. At the very end of the building process, when the foundation’s cladding has already been completed, this structure is built.
- Protective function – when a large amount of precipitation falls, it gets into a special drain for drainage, preventing contact of the foundation with water. If there is no blind area, water can eventually destroy the base of the entire house.
- Prevention of swelling of the soil layer – the foundation structure will not be damaged if the freezing of the soil is minimal.
- Thermal insulation ability helps to retain the heat of the house, preventing the soil from freezing in the cold season.
- Decorative role improves the appearance of the house, making it complete and finished.
To ensure longevity and efficacy in shielding your foundation from water damage, the ideal concrete mix must be created for a blind area. You can confidently prepare the mix yourself if you know the proper ratios of cement, sand, gravel, and water, measured in convenient buckets. This tutorial will take you through the easy steps and provide helpful advice to help you achieve the perfect composition, so that your do-it-yourself project is successful and easy.
Requirements for the blind area
Its ideal width is one meter, and it should extend 200 mm from the house. This gives you the ability to use the blind area surrounding the house as a pedestrian path.
The foundation as a whole will be protected if the entire perimeter of the structure is continuously covered. The thickness, which averages 7 cm, is chosen based on the operational load. The concrete layer can reach 16 cm when the load is increased.
Building the blind area at a slight slope with an angle of at least 1-2º is advised to ensure that water drains from the house during periods of heavy precipitation.
The foundation base will be better shielded from too much moisture the wider the structure.
A significant part of the blind area consists of expansion joints. composed of EPS sections or vinyl tape with a thickness ranging from 5 to 12 mm. situated where the foundation and blind area structure converge.
Components and proportions
Only by closely adhering to all proportions will a good concrete solution for the blind area be obtained.
The traditional approach that aids in accurately estimating the concrete proportions for the blind area is as follows:
- Sand and cement are placed in the mixer in a ratio of 1:3.
- Water is added, when mixing it should produce a mass of uniform consistency, having the appearance of thick sour cream.
- While mixing, add at least 3 parts of fine crushed stone or gravel.
- 300 kg of cement;
- 1120 kg of crushed stone with a fraction of 5-10 mm;
- sand sifted and washed from excess impurities and soil in the amount of 800 kg;
- water in the amount of 180 l.
When combining concrete mortar, each new ingredient should only be added once the preceding ingredients have completely dissolved.
When making concrete by hand, all the ingredients are combined in a big container, like a bathtub or trough. The solution is first blended with a hoe; it is preferable to blend with a bayonet shovel once crushed stone or gravel has been added.
The blind area will be high-quality and long-lasting if high-quality concrete mortar components are used, proper mixing techniques are used, and strict proportions are followed.
Concrete for a private house blind area with your own hands
After winter, a low-quality blind area becomes apparent; it merely breaks up and splits into tiny fragments, sometimes entirely. Most frequently, the cause is a result of using subpar cement to create the concrete and improper mixing techniques.
- For this, take the material of the M200 grade, it is possible and higher, because.. the higher the grade, the higher the quality of the entire structure will be.
- Sand is taken purified, without admixture of clay, limestone, silt. Sand in buckets brought from a quarry or river is better suited for this.
- Crushed stone or gravel should be of a small fraction (from 5 to 20 mm).
- The more water, the lower the strength of the concrete structure.
- When selecting the composition of concrete for the blind area, the proportions must be as follows: 1 part cement, 4 parts crushed stone, 2 parts sand, water 0.5 parts.
Quality of components
The quality attributes of the cement will have a major impact on the service life. Both too much moisture and different kinds of particles—especially solid ones—should be absent from the cement. Only reliable vendors should be used to purchase building supplies. e
When purchasing cement, it is essential to consider its expiration date because the first three months following production are when it is at its best in terms of quality. The strength indicators start to decline after this time.
It is preferable to use higher-grade concrete to fill the top layer of the structure, as this will strengthen the entire thing.
Concrete marking
The strength of concrete as a result of compression is indicated by its grade. Technical characteristics regulations – GOST 912897, 747394.
Considerations such as soil properties, climate, and load must be made when selecting a specific brand. The blind area needs to fulfill the following specifications:
- grade M200;
- strength B 15;
- frost resistance F150.
The most widely used remedy The most common application for M200 is in construction; it is made from M400 cement. It can be used to pour screeds, build stairs, and build a house foundation.
It is preferable to use M250 when constructing in regions with frequent heavy precipitation and abrupt temperature swings. This grade is less prone to crack and is most resistant to extreme heat and cold.
Since vibrations can destroy too-low grades, the larger the construction site, the higher the grade should be.
Proportions for concrete M 200
The most widely used solution derived from M400 cement is M200. The most accurate component ratio must be ascertained prior to producing concrete of this grade. The amount of product needed for 1 m³ is:
- cement – 330 kg;
- gravel – 1260 kg;
- sand – 650 kg;
- water – 170-180 l.
Preparation
The finished solution for making the blind area must be of high quality, without lumps, for this all actions in the preparation must be consistent.
It is first manually prepared by pouring it into a concrete mixer or container, adding a small amount of cement and mixing everything together. Sand and crushed stone are added in the following step.
For a blind area, choosing the proper concrete mix is crucial to its longevity and durability. Strong and dependable results can be obtained by measuring the ingredients precisely and following the right proportions in buckets. The integrity of the concrete depends on accurate measurement and consistency, both of which can be achieved with this simple approach.
The right proportion of cement, sand, and gravel is essential when preparing concrete. Generally, it is advised to use a mixture of one part cement to three parts sand and three parts gravel. To get the right consistency without making the mixture too wet or too dry, slowly add water to the mixture as you mix. Maintaining consistency in the mixing process guarantees proper concrete setting and strength retention.
Self-pour concrete can be a rewarding and affordable project. You can create excellent concrete for your blind area by knowing the ratios and how to mix it. This do-it-yourself method not only saves costs but also offers you the satisfaction of finishing a long-lasting and useful piece of real estate. If you take meticulous measures and pay close attention to details, your concrete blind area will function well for many years.
