But to function properly, slip dowels must be aligned perpendicular to the construction joint and parallel with each other and the slab surface; if they aren't, the slab may exhibit spalling, cracking, and reduced load-carrying capacity. The first houses was built in Västertorp, Sweden, and Bygging became pioneers around the world with slip forming technique, from 1980 with the name Bygging-Uddemann. Slip forming relies on the quick-setting properties of concrete, and requires a balance between quick-setting capacity and workability. The blade cuts a joint into the hardened concrete as soon as the surface will not be torn, abraided or damaged by the cutting action. The width of a concrete slab control joint is the same as the control joint insert (1/4' to 1/2" in width) or of the vee-trowel (about 3/8" wide), or of the saw blade used to make the cut after the concrete has hardened - typically about 1/8".
