Why Does Concrete Sink?

Concrete sinks because it is heavy! Often times, concrete is poured on soils that are unable to support its weight, shortly after the concrete will sink. This is called slab settlement, and this uneven concrete frequently happens in the Houston area. This happens to driveways, sidewalks, walkways, pool decks, and even pools.

Once the underlying soils begin to move, the concrete may only be partially supported, resulting in cracks in the concrete and concrete even shifting away from other pieces.

Concrete's Worst Enemy

Water is concrete's worst enemy, in particularly moisture as a whole. It will seep below the concrete, through pores in the concrete, through missing joint filler and low soil levels adjacent to the slabs. This moisture causes small spider cracking on the surface.

Concrete is extremely durable, but it is not indestructible. The evaporation of the moisture destroys the pores and weakens the concrete. The pores also absorb dirt and chemicals that stain the surface.

Primary Causes of Sinking Concrete

Soil Shrinkage, Compaction & Settling

Soil has a natural load bearing capacity, that capacity changes based on soil type.

Soils can also settle and compact on their own, soils that are rich is clay and/or silt, as much of Southeast Texas soil is, will shrink during periods of little rain or drought.

As the soils settle and compact, areas of void below the concrete will form, often times causing the slab above to crack and settle.

Washout of Soils

Our soils that are below your concrete driveway, patio, sidewalk or other exterior concrete is extremely susceptible to Texas' ever-changing weather and climate changes. Just as compaction or shrinkage can occur during periods of drought, during heavy rains or hurricanes, that soil can wash out or erode. Once this occurs, your soil can provide little to no support for the heavy concrete that rest on top of it.

The Permanent Solution to Fix Sunken Concrete

For years, mudjacking was the go to method for Houston sinking concrete repair - but is that your best option? Mudjacking involves a slurry of dirt injected below the settled concrete. However, if the soils below the concrete are already weak or poorly compacted, the mudjacked slab will more than likely settled again. Making it a temporary repair, often times with a one year warranty.
