3 Main Causes of Concrete Sinking

Concrete has a variety of uses that range from buildings, driveways, patios, parking areas, and verandahs. Concrete serves as a perfect idea to create a solid ground that remains dry, is resistant to harsh weather conditions, and can accommodate the weight. The compressive ability of concrete makes it most suitable for the various uses it is put in. However, there are times that concrete sinks either a few weeks after construction or after a few months or probably years.

When concrete sinks, the ground looks cracked, there are portholes, the ground becomes uneven, and the place seems clumsy. Concrete leveling is the best solution to concrete sinking because it is cost-effective and serves as expected. For you to understand why concrete sinking happens, here are the three leading causes of concrete sinking.

 Infective compaction during construction

The soil is compacted to harden it before constructing concrete slabs on driveways, porches, patios, steps, sidewalks, and other construction requirements that require concrete slabs. Concrete has high compressive strength and is suitable for building slabs that are frequently walked on or subjected to weight. On the other hand, however, concrete has low tensile strength, which is why it is reinforced with steel or iron in some cases.

It is not always necessary to reinforce the concrete in driveways, sidewalks, patios, and steps because these places are not subjected to excess weight. Instead, the soil is compacted for concrete to have a solid place to lie on. Poor compacting traps air holes and spaces within the earth, and when concrete is placed on that soil, air holes are formed within the ground, and since the soil is weak, a space is left beneath the concrete. Because concrete has low tensile strength, it collapses into the formed holes in the soft ground, causing it to crack and sink. Concrete repair and maintenance are necessary when such happens, and concrete leveling works best in these circumstances.

Seeping of water in the soil

The soil beneath the concrete is what keeps level and prevents it from sinking. This is because concrete cannot withstand much weight without reinforcement. In the case of most driveways, patios, steps, porches, and other areas that not much weight is exerted on, the soil beneath the concrete acts as the reinforcement. The compacted soil helps concrete maintain a firm position. However, when water seeps into the ground below, it softens and compromises its ability to hold the concrete. As a result, concrete breaks and sinks when weight is subjected to it. Commercial services/construction professionals can, however, handle that easily.

 The flow of water at the edges of the concrete slab

Water is quite good at eroding soil, and you need to be sure that if rain or drainage water passes next to your driveway or any other place, you have a concrete slab installed on the ground. The soil will get eroded. When the soil is eroded, empty spaces will be left at the edges of the concrete slab, and with time the holes and trenches created will be bigger. As a result, the soil below will be weak, and the holes and trenches created will make the soil underneath your concrete slab lose. If this has been one of the causes of concrete sinking in your home, then concrete leveling is the ultimate solution.
