Building a house only in breeze blocks is possible. But in masonry, each block of block has a very specific use... So what can be the block to bancher, with their H shape so special?
The blocks to bancher
What is a bancher block?
The boulder block is a block of block, as well as the hollow block, well known in the construction of detached house.
But all the blocks of cinderblock have their specificity, it is besides why there existshollow block, lintel block, post block… ).
The specificity of the block to bancher? Her H shape, which allows to easily insert reinforcements. Once these are inserted, we will sink the concrete directly into the cells of the block to bancher.
The walls in blocks to bancher are thus walls very solid and very resistant, like the walls in reinforced concrete.
Use of the blocks to bancher
The fact that we insert frames and especially that we flows concrete directly into the cells of the block gives it a particular use. Indeed, we reserve the block to bancher to the realization:
- Lost formwork. As for the construction of swimming pools for example. Logic: once the concrete form is finished, as the concrete has been poured into the cells, this formwork is necessarily brought to stay in place. Hence its name.
- Retaining walls and underbody. In general, walls that contain land in a small space (to preserve the roads of a landslide, to arrange a bank in dock, or strengthen a base of the foundations of an imposing building.
Bancher blocks: what price?
To build a lost formwork or a solid support wall in bancher blocks does not require a big budget, even if the price of the blocks to bancher is higher than the price of conventional blocks (hollow blocks).
For a standard sized boulder block (20 cm wide, 50 cm long and 20 cm high), it is necessary to count on average 2 € each.
Of course, if you want higher, wider or longer boulder blocks, the price will also increase...
