How Do You Face Interlocking Concrete Blocks?

How Do You Face Interlocking Concrete Blocks?

Applying facing over brickwork can serve to benefit the structure the brickwork is part of. With that being said, does every building material used to make a structure have to have facing? Or is it subject to the structure itself? Are Interlocking Concrete Blocks included in this?

In this blog, we will answer the question ‘How do you face interlocking concrete blocks?’

At PPC Concrete Products, we are here to provide solutions for your construction needs, from the person working their own part-time project, to commercial clients, and everyone in-between.

Monthly construction output had risen an estimated by an 1.6% value in June 2023, and we would like to think our accessible concrete products had a small part to play by giving our clients easy access to reliable and easy-to-use construction solutions.

Why do buildings need facings?

A facing on a building, as the name suggests, is the outermost visible layer, or the ‘face’ of the building.

Facings provide a few benefits for any building, whether that be a home, an office, and more. A facing provides an aesthetic layer over the brick or stonework that also serves to protect the brickwork from outside damage.

Let’s take a house made from bricks, for example. Some houses have regular brickwork on the outside. But, behind that are likely bigger, thicker bricks that created the structure of the home, behind those thicker bricks would be the insulation, plastering, etc. So in this case, the brickwork is the facing of the building.

Some other homes opt for a facing that looks smoother, or whatever aesthetic they’re looking for. Without a facing, a building is more exposed to the elements.  This can include water seeping inside the building and brickwork, a less effective insulation, and in some cases, a reduced level of durability should the home sustain an unexpected heavy impact.

Is it worth getting facing done on a building?

Yes. It is absolutely worth getting facing applied to a new build. Although this will add to the cost of your project, it safeguards your building and helps to prevent any more money being spent on unexpected repairs.

Additionally, the occupants of the building can be more comfortable, and safer.

What kind of structures benefit from facings?

Here are the kind of buildings that would benefit from having facings outside of the aesthetic benefit…

  • Houses
  • Blocks of flats
  • Offices
  • Venues
  • Restaurants/ food establishments
  • Shops
  • Banks
  • Schools
  • Colleges
  • Universities
  • Historical/listed buildings (that are allowed to have facings).
  • Religious buildings such as a mosque, church, or synagogue

There are more types of buildings that would benefit from having facings. As a rule of thumb, any building that is designed to be a permanent fixture, would benefit from facings.

How do you face Interlocking Concrete Blocks?

What is a flat top concrete block?

Firstly, it is important to understand that our Interlocking Concrete Blocks do not require facing, it is completely subject to your needs and preference.

Facing our Interlocking Concrete Blocks is simple. Though, the complications may occur when it comes to how you want to face them. Depending on what you want over the blocks, it can be as simple as applying a layer of paint, or adding mortar to attach your chosen cover over the blocks.

However, there is an easier option. We at PPC offer ‘rock faced blocks’. Rock faced blocks have all the same functionality as our Interlocking Concrete Blocks, with the difference of a more natural, and less industrial aesthetic.

They serve as an aesthetic alternative for anyone who wants a little more character with their Interlocking Concrete Blocks. In terms of the physical difference, they are shaped like our regular Interlocking Concrete Blocks but appear to have rocks and stones showing, rather than the smooth, flat grey side surfaces of our regular blocks.

We would not recommend facing our Interlocking Concrete Blocks if they are exclusively for a temporary structure. If your facing requires mortar, taking it off whilst removing the blocks can prove to be an exhaustive and potentially dangerous process.

What happens if Interlocking Concrete Blocks are not faced?

Because our Interlocking Concrete Blocks aren’t used to create permanent dwellings, the purpose of applying facing to a structure made by our blocks would be to either preserve the concrete, or for aesthetic purposes.

With that understanding, if your structure is in an environment where the concrete is getting chipped away, applying facing could help.

Interlocking Concrete Blocks explained

Interlocking Concrete Blocks explained

Interlocking Concrete Blocks are a building solution that can be used in a variety of situations over traditional brick and mortar builds, and builds that use other materials. Interlocking Concrete Blocks contain studs and recesses at the top and bottom of the block respectively that allow them to join together without the need for mortar to bind them.

The hold provided by the blocks is almost impossible to detach without the use of heavy machinery. Furthermore, due to the durable nature of concrete, you can use these blocks to create structurally sound, reliable and durable structures that are weatherproof, and extremely heavy.

The heaviness of the blocks, in conjunction with the interlocking feature, provides a secure level of structural integrity that is extremely difficult to topple or alter in any way once the structure has been set.

Regarding the weight of our blocks, they individually weigh 1560KG depending on the size of block you opt for. In conjunction with this, the interlocking and stacking features of our blocks provide an extremely secure structure.

Our interlocking concrete blocks have the potential to have 5 blocks stacked upon each other. Our standard-sized blocks are 60 cm in height, with 5 stacked together this would equate to 300 cm, which is exactly 9 feet (2.74 m) & 10.11 inches (ca. 26 cm) high.
