140mm 390 Series (mix) Tongue-and-Groove

140 mm wide hollow blocks are a versatile choice for building the walls of residential and commercial buildings. The tongue-and-groove joint speeds up laying and ensures an even, strong masonry.

ARC140 is a 140 mm wide hollow concrete block that combines sufficient strength with good thermal insulation. The block is suitable for building both load-bearing and non-load-bearing walls in residential and commercial buildings and is especially common when building basement and plinth walls.

The tongue-and-groove end face ensures convenient, precise installation and reduces mortar consumption. The cavities inside the block allow additional reinforcement with concrete where needed, noticeably increasing the load-bearing capacity of the structure.
