    What Causes Sunken Concrete?

    The most common question we get from clients when quoting a new project is, “what causes my concrete to sink in the first place?” Most often, the problem is from one source – the soil below your concrete slab. Concrete will sink when the integrity and stability of the earth below the surface have failed.

    In most cases, one of these three problems cause underlying soil failure:

    • Poorly Compacted Soil
    • Excess Water in the Soil
    • Excess Drying of the Soil

    During the construction process for any new concrete work such as a new foundation, driveway, or steps, a builder will first have to level the area using fill soil before pouring the concrete. The new earth will not be as dense as the soil beneath it; therefore, the builder or concrete contractor must ensure to compact the ground to increase the density and stability. If the soil is not compacted correctly before concrete pouring, it will eventually settle, causing the concrete slab above it to sink and crack.

    Moisture levels in the soil below your concrete also play a crucial role in the stability of your slab. If the ground becomes excessively dry, it will shrink, potentially creating voids into which the concrete can sink. On the opposite end of the spectrum, excess moisture caused by heavy rain can soften the soil and clay beneath the concrete. Soft ground does not have the integrity required to hold heavy weights and therefore is prone to having concrete sink into it. For these reasons, it is essential to keep a close eye on your concrete slabs during the dry and wet seasons. If you see any signs of your concrete sinking or cracking, contact our team immediately. We will come out and inspect the area and provide our recommendation for how to best proceed.
