Explaining The Top Causes Behind Your Sinking Concrete

Nov 5, 2018 | Cement Leveling Houston

Over the years, you may begin to notice small cracks forming along the concrete surfaces on your Houston property. While normally minor in size and depth, these damages may be a warning sign of future problems. Many Texas homes experience some issues with uneven concrete surfaces, as long-term use and seasonal changes can wear down your slab and cause it to shift with no discernable pattern. Instead of watching this settlement grow worse, you can invest in concrete-leveling services to restore the beauty and uniformity of your slabs!

Incomplete Soil Conditioning

In many cases, the long-lasting support of your subgrade will play the biggest role in keeping concrete in place. Earthwork crews need to have a working knowledge of the materials being used in construction to ensure that every soil is properly treated before placement. Your Texas home will have one of two (or both) materials beneath the foundation:

  • Native soils, which consist of the materials available on the jobsite. Texas soils are unique in comparison to other parts of the country, which is why our personalized concrete leveling services are in such high demand!
  • Imported soils, which often include clean fill materials from a nearby source. In many cases, the pit this dirt is sourced from will provide proctor results (refer to ASTM standards) to highlight the ideal levels of moisture and compaction.

Part of “reconditioning” your soil includes excavating down to the required depth and backfilling the space after changing the moisture content of the materials available. The soils on your property will have an optimal moisture content, allowing for a certain amount of variation on either the wet or dry side before things go south.

Expansion Problems

Expansive clays need to be conditioned before being used in construction, as the Houston area is comprised much of clayey soils that have a very high shrink-swell potential. This means that leaving your clay too dry (say, 14 percent moisture when the design spec calls for a minimum of 19 percent) can create a huge swell potential. When water is introduced, these clays will begin to expand, causing the concrete above to crack and heave. Upon losing this moisture, clay will begin to shrink and contract, causing the concrete to sink.

Insufficient Compaction

Soil is used in most construction projects, and is often required to undergo earth compaction techniques to ensure that the materials are cohesive and sturdy. Failing to properly compact your dirt will allow for more pore space, creating a number of concerns. Most construction applications will require your soil to be compacted to at least 95 percent of its maximum density. By compacting materials, your crew will help to reduce water infiltration, soil degradation, and more. Failure to put in enough compaction efforts may leave your materials soft and open to future compaction and settlement, leaving concrete unsupported and primed for failure.

While the soil that sits beneath your concrete may often feel out of sight and out of mind, it’s important to remember that this material can play an important role in the long-term durability of the surface on top. Even if your soils are treated properly, long-term degradation, erosion, and settlement can all play a part in impacting the quality of your slab.
