We are updating our serie of Concrete and Cement Walls. This mean that initially this thread was for volume 3 and you are now seeing Volume 5 and Volume 6 ... You are not mistaken and we are not either.
If you have volume 3, go check out the appropriate thread about it : it was updated
If you like our serie of Concrete and Cement, check it out, those are two new volumes !
