Wannan yana haifar da 'saitin', inda tsayin kyauta $H_{free}$ ya ragu. Danniya a tsayayyen tsayi $\sigma_s = \frac{3 π E t (H_{free}-t_{solid})}{4 N^2 D_m^2}$ yakamata a kwatanta shi da ƙarfin amfanin gona. Idan $\sigma_s > \sigma_y$, ruwan bazara ba zai dawo zuwa ga asalinsa ba. A wasu matakai na masana'antu, ana yin 'presetting': ana matsa ruwan bazara zuwa tsayi mai tsayi don 'cire' saitin farko da daidaita nauyin.
