How fast can hit the wall, with a hammer
If it is a brick masonry wall, can use big hammer ah, not a yellow sledgehammer on learning about the Spring Festival. But the size of operation is out of control, you need a 1000 wide, non hit a 1300 can not be hit over again from the new patch laying bricks, especially the window head, it must be very wide, and then make a prefabricated cement top up, that is the beams, so as to protect card wall weight is not pressure in the window.
If it is the concrete wall, it must be hit with a diamond, but the equipment is not good enough.
Don't tamper with the load wall! If you do not want to hit the end of trouble, or hammer and chisel, and slowly get more regular.
