Neil · Answer

A class bricks will have clean smooth faces , all bricks will be similar size and shape.class b bricks faces can be not as smooth .length and shape can vary.

Lukasz · Answer

Class A Engineering bricks will offer a compressive strength of 125N/mm² or more, and will absorb less than 4.5% of water. A Class B brick however will offer compressive strength of more than 75N/mm², and will boast water absorption of less than 7%.

Chris · Answer

Class a is load bearing of 125n/mm2 and class b is 75n/mm2 so class a is much stronger normally used underground and class b normally above ground but I wouldn't use class b because they seem to blow and crack in the winter

Tony · Answer

A class engineering bricks are rated as stronger at 125kn and less water absorbent by3%

Kieran · Answer

Class a engineer bricks absorb 4 or 5% less of moisture and class b engineers absorb less than 7 or 8% of moisture class a and b also have different compression strength levels

.joseph · Answer

Class a engineering are a solid form of brick class b have holes in
