Cupping vs Buckling

Cupping is a result of slow moisture attrition from underneath. Buckling indicates a fast, massive amount of moisture attrition. With Buckling part of the floor has actually lost contact with the substrate. Cupping is when the edges are higher than the center of the board. Comparisons, cupping vs buckling reveal both caused by moisture and not necessarily poor installation.

More about Cupping

Noticeable cupping that shows up over the span of a few days is likely because of underlying water damage. It may point to a serious problem, such as leakage. Floors that cup because of too much water vapor in the air will warp more gradually. Those culprits are more difficult to discover since there are no immediate changes.  So again, cupping vs buckling comparisons provide answers to the type of water issues.

Buckling, the opposite of cupping

Excessive moisture also creates buckling in solid wood floors, engineered wood, and laminate. Regarding the nature of the damage, buckling is the opposite of cupping. It bows the other way, forming grooves and peaks. Many time buckling occurs over concrete slabs with hidden extra moisture.

Helping to prevent all moisture issues

Make sure there isn’t any standing water in the crawlspace or basement under your house caused by plumbing leaks or drainage problems. Be sure the ground slopes away from your house, and rainwater is diverted away from the foundation. If problems with high humidity in the crawlspace or basement under your house persist, consider closing up all vents and installing a dehumidifier under the house or conditioning the space under the house.
