WebThe Interpretive information associates with a soil map also addresses shrink – swell. The map units are rated for their shrink – swell potential, generally low, moderate, high or very high. Current building code required the building plan to address the problem if the soil map for the project area shows a rating of “moderate” or higher. WebShrinkage is the main cause of cracks, when concrete hardens it evaporates the excess water and thus shrinks, so lesser the water content, lesser is the shrinkage. Cracking shrinkage in slabs is ½ inch per 100 ft. The shrinkage of concrete pulls the slab apart showing it as cracks on surface.
