What Is Dense Hollow Concrete Block 7.3 N x 215mm?

215mm x Dense Hollow Block 7.3N is an adaptable construction material perfect for numerous building applications. 


With their hollow design, these hollow concrete blocks are more lightweight than solid blocks, easing the handling process and reducing the burden on floors and foundations. 


Despite their lighter weight, they do not compromise on strength, making them a suitable choice for constructing load-bearing walls, including retaining walls, external walls, and partition walls. This versatility also extends to the creation of cavity walls and party walls. 

Apart from providing a sturdy base for fixings, this 215 x hollow block offers notable fire resistance and sound insulation properties, which enhance the safety and comfort of the built environment. 

What Are Hollow Blocks?

Hollow blocks, commonly known as Concrete Masonry Units (CMUs) or cinder blocks, are a fundamental component in modern construction.


They are rectangular, larger-than-brick units made from a mixture of cement, sand, and water, then cured under optimal conditions.


What sets hollow blocks apart from other masonry units is their unique structure. They are characteristically 'hollow', with one or more cores or voids running through their centre.

This hollow configuration contributes to their lightweight nature, simplifying transportation and handling during construction.


In terms of local availability, we stock quality hollow blocks nationwide. Should you wish to arrange collection, please reach out to our friendly
customer service team via email or phone.

For all other bricks and blocks please refer to our designated bricks and blocks page. If your project requires a pack, we also supply these on our block packs page.

Hollow Block Applications

The distinctive hollow structure of hollow blocks doesn't inhibit their strength, making them an excellent choice for various construction purposes.

You'll find these blocks in the construction of both interior and exterior walls, be it load-bearing walls, partition walls, or even in the creation of cavity walls.


Let's outline some of hollow concrete blocks' most popular applications below: 

  • Load-bearing walls in residential and commercial buildings
  • Partition walls for interior spaces
  • Boundary walls for property demarcation and security
  • Foundation walls for building stability
  • Soundproof walls for noise reduction
  • Construction of columns and beams

215mm x Hollow Block Characteristics

  • Lightweight and easy to handle
  • Excellent insulation properties
  • Versatile applications in load-bearing walls, partition walls, and more
  • Effective sound insulation
  • Durable and long-lasting construction material
  • Locally available for convenient access

Hollow Blocks Vs Concrete Blocks

When it comes to choosing between hollow blocks and solid blocks, it's important to consider the specific requirements of your construction project. 


Hollow blocks, as the name suggests, have hollow cores that make them lighter and easier to handle. They offer excellent thermal and sound insulation properties, making them suitable for applications where insulation is a priority. 


On the other hand, solid blocks are denser and provide greater structural strength, making them ideal for load-bearing walls and areas that require added durability. 


Ultimately, the decision between hollow and solid blocks depends on factors such as structural needs, insulation requirements, and project specifications.
