Reasons for the destruction of bricks on the facade: systemic wetting; risk zones; masonry advice

When choosing one or another building material, we pay attention to the manufacturer and his reputation. But in some cases, the manufacturer and his products are not so important as the external factors in which the building material will be used. Participant our portal under the nickname Negativ claims that you can choose any facing brick, you just need to use it correctly.

Yulia, FORUMHOUSE user:
"Share information or experience (good or bad - it doesn't matter) about the manufacturers of Russian ceramic facing bricks or the intricacies of masonry. We have built a 2-storey house box, but I can’t decide on the facing. Each dealer praises his own version and speaks negatively about competitors. Help, please, give valuable advice on choosing a brick! "

The brick is not to blame, but external factors

FORUMHOUSE member under the nickname Negativ:

"You can take absolutely anyone, but the brick has nothing to do with it. If the brick is not clinker and there are conditions for systemic wetting, destruction is inevitable on any brick. The only question is time. "

Important about frost resistance

What is frost resistance? This is the number of cycles of alternating freeze-thaw in conditions of complete moisture saturation. How is it tested? The brick is immersed under water for 48 hours, then it is alternately frozen / thawed until signs of destruction appear or until the declared frost resistance index is reached. Testing is expensive, so many manufacturers save money and ask for a parameter within 50–75 cycles, less often - 100. And what are 50 cycles if there can be up to 40 zero-crossing cycles in central Russia per year?

Risk areas for facing bricks

On the other hand, if the masonry is protected by eaves overhangs at the top and a plinth at the bottom, there are no leaks, the masonry can withstand decades. IN risk zone most often there are open structures: chimney heads, fence posts, houses with flat roofs, parapets, etc.

The situation is aggravated by the total laying of bricks for bars throughout the country. The brick should be laid only in a full seam. The brick should be with a thickened front wall of more than 20 mm. If peeling of bricks occurs on the facade, the problem is not in the factory in 99% of cases.
