There are three important mechanical stressors that can cause debonding over time. The first, mechanical stress is from the work done by water and capillary action. There can be microscopic areas where the bond to the concrete is tenuous. If the waters adhesion to the concrete is locally greater than the adhesion, than this could disbond the adhesive from the concrete. The second source of mechanical stress is from temperature changes of the floor. If the temperature and humidity changes significantly and regularly, then the expansion and contraction in the flooring product can cause lateral stress that will further weaken bonds. Over time, this will cause a buckle or warping in the flooring. The third mechanical stressor comes from regular use and advanced use. Advanced use comes from moving heavy equipment over weakly bonded areas. In the end, these mechanical stressors can cause debonding to occur over a long period of time.
