They are more expensive per sqm than traditional bricks, but they lay faster because you need less, so the savings might come from lower labour and mortar costs..When using M140 bricks for a standalone garage. I'm guessing it's cheaper and faster to build with but the tradeoff it's not as "nice" ? Or what are the drawbacks?
They absorb moisture, so need to make sure waterproofing is done right.. shrink while curing, so hairline cracks are inevitable.. you can plaster them to get rid of the not so nice look though.. then there's also the mounting things to a wall aspect.. the majority of m140 is hollow and the wall thickness is only two or three cm on the hollow sections, so need to carefully plan any thing heavy you want to mount to the wall and the method used..
