3 Reasons Your Concrete Cracks and Sinks

Soil Dehydration: Soil naturally undergoes compaction and settling, particularly under pressure. The soil type is pivotal—clay or silt-based soils are susceptible to contraction as they dehydrate, akin to a sponge. When soil loses moisture, concrete may settle, leading to the formation of fissures and uneven surfaces.

Erosion: Water plays a significant role in the development of cracks or subsidence in concrete. As water permeates through the concrete, it can erode the underlying soil, causing erosion. In the absence of adequate support, the concrete slab may sink. Imagine standing on a shoreline while waves lap at your feet—gradually, the ground beneath you is washed away, causing you to sink.

Compression & Subsidence: The pressure exerted on soil results in its compression, often due to inadequate soil compaction prior to concrete placement. Similar to compressing a ball, soil condenses when subjected to force. Prolonged pressure can create uneven support for concrete, leading to subsidence.
