Crack Beside Sawn Joint So, in this case, this is still a shrinkage crack the purpose of that sawn joint was to avoid this crack forming or to relieve the stresses in the concrete that caused this crack to form. So now we see some more abraded concrete – the surface layer is lost and the stones are very well exposed.
