All possible sizes of borders

The finer points are crucial in construction project planning. Borders, sometimes referred to as curbs or edging, are important for demarcating areas and giving any outdoor space a polished appearance. From garden paths to expansive commercial projects, borders are available in different sizes, each meeting distinct functional and aesthetic requirements.

Small borders are usually 4 inches high and are frequently used in gardens and residential settings. These are ideal for creating a tidy border around landscaped areas, dividing flower beds, and preventing grass from growing into pathways. They are versatile in design and easy to install due to their small size.

Medium-sized borders, about 6 to 8 inches high, are typical of larger landscaping designs. Larger garden areas, driveways, and walkways can benefit from their increased stability and durability. Many homeowners and landscape designers choose this size because it strikes a balance between practicality and aesthetic appeal.

Larger projects, like public areas or commercial buildings, may have borders that are significantly higher—up to 12 inches, in some cases. For heavy-duty applications, such as parking lots, roads, and locations with lots of foot traffic, these wider borders are necessary. They can sustain considerable wear and tear without losing their structural integrity thanks to their substantial size.

Making informed decisions for your unique project requirements is made easier when you are aware of the different border sizes that are available. Whether you’re designing a large commercial space or improving a small garden, the practicality and aesthetics of your project can be greatly affected by the size of the border you choose.

Border Type	Dimensions (mm)
Standard	1000 x 150 x 50
Heavy Duty	1000 x 200 x 75
Garden	600 x 100 x 50
Pathway	450 x 150 x 50

GOST requirements for the dimensions of curb stones

The 1991 publication GOST 6665 is the fundamental guide that establishes the dimensions of stones. Its range of use encompasses:

• stone;
• concrete;
• reinforced concrete;
• garden products for inner-city roads and intercity highways.

It offers the following primary features:

1. length: 0.5;1.0;3.0 and 6.0 m;
2. width from 300 to 450 mm;
3. height from 150 to 180 mm.

Concrete stones up to three meters in length can be obtained by vibration pressing and vibration casting, in addition to natural stone products:

• granite;
• gabbro;
• travertine;
• quartzite.

Items longer than three meters are composed of reinforced concrete, which has internal reinforcement from class A-4 non-stressed reinforcement.

GOST states that curbs can be made in six different ways based on shape:

1. ordinary rectilinear;
2. rectilinear with expansion;
3. rectilinear with contour width;
4. straight with a gutter;
5. curb;
6. radial or curved.

For road stones, these products are composed of concrete classes B22.5 and B30, and for highway stones, B>30. In this instance, granite or reinforced concrete products are required. These indicators will determine their weight, which for stone and concrete is between 60 and 1400 kg.

There are no set mandatory regulatory requirements for the sizes of curbs made of plastic, rubber, or metal. The manufacturers voluntarily certify these modifications, which are created in accordance with factory specifications.

These stones are not your typical products. These products can frequently be customized to fit the specific sizes of each customer; this is particularly true for metal goods.

It should be remembered that curbs and borders have the same standard dimensions and are composed of concrete, reinforced concrete, or natural stones; their installation methods vary, though.

On one side, the curb is installed at the sidewalk’s level, and on the other, it is raised above the road to a standard height. On both sides, the curb is positioned at a specific height above the road and the sidewalk.

Depending on the purpose

Curb product sizes vary depending on the installation location. The strongest ones are placed on major thoroughfares where a lot of trucks pass by; they also need to be stronger than B 35, resistant to freezing temperatures (F300), and have a longer lifespan than 20 years.

These jobs are best suited for 1 to 3 m length concrete products, 3 to 6 m length reinforced concrete, and 0.5 to 1 m length granite stones.

The primary curb dimensions listed in GOST 6665, which was released in 1991:

• concrete 1000 x 300 x 180 mm, 120 kg;
• concrete 1000 x 450 x 150 mm, 140 kg;
• concrete 1000 x 450 x 180 mm, 190 kg;
• reinforced concrete from 3 to 6 m with a section of 300 x 180 mm, from 384 to 648 kg;
• Reinforced concrete from 3 to 6 m with a section of 450 x 180 mm, from 518 to 1170 kg;
• granite GP 2 1000x180x400 mm, 195 kg;
• granite GP 2 2000x180x400 mm, 390 kg;
• granite GP 3 1000x200x600 mm, 324 kg;
• granite GP 3 2000x200x600 mm, 650 kg.

Granite and vibro-pressed, vibro-cast reinforced concrete are the most common materials used for road curbs in high-stress areas. Lower strength requirements from B 22.5 and frost resistance from F200 apply to them. In 90% of cases, these changes are implemented in populated areas and urban improvement systems.

Most typical lengths of travel:

• concrete – 1000 x 300 x 150 mm, 100 kg;
• concrete – 1000 x 300 x 180 mm, 120 kg;
• granite GP 1 – 1000x180x300 mm, 122 kg.

The most resilient granite and concrete vibropressed stones in compliance with GOST 6665 are used to make garden borders. These materials can be produced in lengths of 500 mm and 1000 mm, heights up to 200 mm, thickness up to 80 mm, and weights between 18 and 36 kg.

Depending on the material of the curb

For these products, the most widely used material is:

• concrete;
• reinforced concrete;
• granite is used less often.

These materials are used to make curbstones in:

1. construction of road surfaces and sidewalks to separate the roadway from pedestrian paths;
2. green areas and public transport stops.

Apart from their primary function, reinforced concrete, granite, and concrete stones contribute to the road’s visual appeal and help with surface upkeep and functionality. They are very easily maintained and can be changed if needed without causing harm to the curb structures in other areas of the road.

Due to the high demand for garden-style curbs in private housing construction, polymer-sand, plastic, rubber, and metal can be used to produce them in unstressed areas.

Utilizing cutting-edge technology, polymer sand products are made from leftover food plastic and sand. Measuring 500x200x80 mm, they fit perfectly on standard garden concrete pavers and walkways with tile or stone surfaces.

Strips of plastic and metal measuring 3 to 10 m in length, 100 mm in height, and 2 mm in width for steel and 5 mm for rubber and plastic are produced.

How to determine which one is right?

The final purpose of the road surface determines the size of the curbs and how they are modified; the construction product must be such that it prevents the paving material from being destroyed and fits in with the improvement area’s landscape design:

• For highways and city roads choose highway and road curbstone made of concrete, reinforced concrete and natural granite of gray color.
• When arranging park areas use regular gray road curbstone with standard sections of 300×150 mm or a narrower size of 200×80 mm. Sometimes curbs with a gutter are installed here so that it is possible to work with a lawn mower. The length of the products is 1 m; for curved sections, stones with a length of 0 are used.5 m.
• For weak soil special curbs with a wide base are installed to prevent soil and main road surface subsidence.
• For landscaping of private housing construction 500x200x80 mm curbs made of concrete, obtained by vibration pressing, vibration casting or polymer sand stones are most often used.

They can match the color scheme of the house objects and pathways, and they can be any color. Thinner and narrower products made of plastic, rubber, and metal are used for the garden’s green areas and vegetable garden. These products serve as a decorative barrier between these areas rather than bearing a heavy mechanical load.

Principal curb sizes for various functional zones:

1. Intercity roads and highways: main concrete, reinforced concrete, granite: 3000x300x180mm; 1000x300x180mm; 6000x300x180mm; 3000x450x180mm; 6000x450x180mm; 1000x450x180mm; 3000x450x150mm; 6000x450x150mm; 1000x450x150mm, gray color.
2. City roads – road concrete, reinforced concrete, granite: 1000x300x180; 1000x300x150; 3000x300x150; 500x300x150 mm, gray, sometimes colored;
3. Sidewalks – concrete and polymer sand stones: 500x200x80; 500x150x60; 500x150x40 mm, gray and colored.
4. Gardens and parks – concrete, polymer sand stones, plastic and rubber; length from 0.5 m for concrete and polymer sand stones; up to 2 for stainless steel fences; up to 10 m for rubber and plastic; cross-section from 150×80 mm for concrete and polymer-sand stones; up to 2 X 100 mm for steel; different colors.

You must select high-quality products when deciding on border size and modification. To achieve this, only purchase them from reputable vendors who have quality certifications. These documents have to list the product’s attributes, manufacturing process, measurements, and GOST compliance.

It’s crucial to keep an eye on the certificate’s issue date to make sure it hasn’t expired. If such a document does not exist, the products are probably of low quality and will not be able to fulfill their intended purpose because they are not resistant to mechanical or atmospheric influences, such as moisture and frost.

Only the roadway construction project, during the design calculations of all loads on it and taking into account the terrain, climatic, and geological characteristics of the territory, determines the modification of curbstones for the road surface of highways, city, and inner-city roads. These indicators are established in the landscape project for private construction.

The following considerations must be made when selecting curb sizes if the developer intends to enhance a portion of the neighborhood on his own:

1. Know the height of the underlying layers that will be used to strengthen concrete, reinforced concrete, granite and polymer sand stones, usually from 30 to 50 mm.
2. Consider the depth in the ground from 50 mm.
3. Consider the thickness of the coating from 50 mm.
4. Consider the protrusion above the coating from 60 mm.
5. The length is selected based on the straightness of the section, for straight ones from 1000 to 6000 mm, and for curved ones – 500 mm.
6. The width is selected according to the load: for highways no less than 180 mm, for city roads no less than 150 mm, for curbs and garden tiles no less than 60 mm.

The integrity of the blind area and underlying layers will be better and longer preserved if the curb stone is installed deeper.

An illustration of how to calculate a fence for a 100 m straight road section is as follows:

1. Determine the length: 100×2=200 m.
2. Take into account a margin of at least 10%: 200×1.1=220 m.
3. Choose a road stone: 1000x300x150 mm.
4. Determine the required amount: 220:1.0=220 pieces.

An illustration of how to calculate a curb for a 5 m curved section and a 60 and 35 m straight road section with a curved L-shaped shape is as follows:

1. Determine the length of the direct section (60+35) x2 = 190 m., with a margin and rounding of 190×1.1 = 210 pieces.
2. Determine the length of the curved area with a margin and rounding to an even number 10×1.1 = 12 m.
3. Select a curb for a straight section of 1000x200x80 mm and calculate the required quantity – 190: 1 = 190 pieces.
4. Select a curb for a curved section of 500x200x80 mm and calculate the required amount – 12: 0.5 = 24 pieces.

Larger, more durable borders for driveways and roadways are available, as well as smaller, more ornamental edges for garden paths. Borders are available in a range of sizes to suit various design and functional needs. Knowing the sizes that are available to you will help you choose the ideal border for your project, ensuring both structural integrity and visual appeal. We examine the entire range of border sizes in this post, offering guidance to help you choose wisely for your concrete projects.

Why is it important to choose the right length, width, height of the blocks?

The right curb size selection affects the overall road surface’s longevity.

Sometimes, in an effort to cut costs, developers will specify a thin, narrow curb that lacks reserve in terms of strength, length, or resistance to frost.

Even if a surface for a road made of such stone is constructed, it will probably fall apart after the first cold season.

Furthermore, weak curbs are extremely difficult to install because they are severely damaged during delivery to the site and during the sidewalk or path installation process.

The road work will need to be entirely redone due to a poorly chosen curb, which will put a heavy financial strain on any developer.

Any building or landscaping project requires an understanding of the different sizes of concrete borders. If you’re working on a small garden or a large public space, knowing your options will help you make the best decisions in terms of aesthetics and functionality. There is a large variety of border sizes available, and each is made to fit a particular set of requirements and tastes.

Because standard border sizes are so versatile and simple to install, they are frequently used in most projects. These usually have a height of a few inches to a foot, which allows for sufficient division and area definition without taking up too much room. Custom sizes can be made to meet specific design or structural requirements for more specialized needs.

Small borders are a subtle but useful addition to landscape design; they are frequently used for garden beds and pathways. For edging driveways and walkways, medium-sized borders work best because they provide greater stability and aesthetic impact. In areas that require durability and prominence, such as parks and commercial properties, large borders work well for defining boundaries.

Concrete borders can be made to look better overall and function better by choosing the right size. Every size has a specific function that guarantees your borders will function well over time in addition to looking great. Choose the border size that best reflects your design concept while taking into account the unique needs of your space.
