This involves drilling holes in an unstable PCC slab or section and injecting an asphaltic or cementitious material to fill any underlying voids. Typically, this method is only an option for isolated instances of instability. It does not work well as a general roadway treatment. Make the flexible structure strong enough to resist cracking.

Grinding For soft and ductile stainless steels, it is strongly recommended that the use of very coarse grinding foil/papers and high pressures are avoided, as these can result in deep deformation. As a general rule, the finest possible grit, consistent with the sample area and surface roughness, should be used for plane grinding.
