Interlocking concrete pavers have anti-slip properties and good shaping performance under various environmental conditions. These pavers are cost-effective, durable, easy to install, and do not require highly complex technical procedures. They are a type of non-fired brick that is prioritized for development due to their environmental benefits.

With these advantages, interlocking concrete pavers are increasingly produced to meet the growing demand of construction projects. Manufacturers are gradually aligning their production with national standards, and TCVN 6476:1999 is the national standard applicable to interlocking concrete pavers.

What are Interlocking Concrete Pavers?

Interlocking concrete pavers belong to the category of non-fired bricks. They are widely used for paving sidewalks, streets, yards, and public squares. The raw materials used in the production of these pavers include construction aggregates, cement, fly ash, coal slag, sand, crushed stone, and industrial waste.

These pavers are manufactured in various sizes, shapes, and compressive strength grades.

Interlocking pavers have many functional advantages and can be used in a wide range of applications. Investment in production lines and manufacturing processes is relatively simple. The production process does not require firing, unlike traditional clay bricks.

As a result, production efficiency can be optimized while contributing to a more environmentally friendly construction material and reducing environmental pollution. Their competitive price and flexible manufacturing capacity make them increasingly popular for production expansion across many provinces and cities.

Types of Interlocking Concrete Pavers

Due to the ease of production investment, interlocking concrete pavers are available in many types. Some common products include:

• Rectangular interlocking concrete pavers

• I-shaped interlocking concrete pavers

• Hexagonal interlocking concrete pavers

• Zigzag interlocking concrete pavers

• Worm-shaped interlocking concrete pavers

• Grass planting interlocking concrete pavers
