![]() But, from winter-to-summer-to-winter-to-summer, it might open-and-close by 1/16” more-or-less. So, the crack might be 1/16” one year, and 1/8” five years later. ![]() But, from winter-to-summer-to-winter-to-summer, it is also opening-and-closing-and-opening-and-closing, due to the seasonal ground movement. So, eventually a crack starts, and over many years it slowly widens. However, the ground swelling-and-shrinkage happens seasonally. Let’s say that we have a reasonably stable building, and the settling factor happened over many years. The crack is going to continue to open-and-close, and usually widens, on-the-average, as time goes by.įurthermore, the crack movement usually exceeds the elastic limits of whatever-was-used to fill the crack, even if it was not cement. Patching the crack did nothing to stabilize the foundation, or change the seasonal swelling-and-shrinkage of the ground. These have underlying them one common denominator: the building is still moving. There are two reasons: The cement patch can’t stretch, and or the caulk did not stick. Render crack repair is often done with various caulks or cement, and usually the crack opens up again. Why Do Repairs To Rendered / Stucco Walls Fail?

Render crack repair is then required to keep the building watertight, this article shows you how. When the building moves, then one part of the foundation goes a bit up, down or sideways relative to another part, and then the render cracks. The rendered walls don’t stretch, not worth-a-hoot. Why Does Render (Stucco) Crack When Used On WallsĬracks appear in rendered walls of buildings because the ground actually moves, and the building actually moves, and with time and the wet/dry/wet/dry annual seasonal patterns, the ground swells-and-shrinks and the building settles somewhat unpredictably over the decades.
