Reasons Why Concrete Patios Sink Over Time
There are several reasons why concrete begins to sink over time. The main reason is because concrete is heavy. Concrete begins to sink when the soil under the concrete can no longer support it’s weight. Areas that are not supported by soil may start to crack causing the concrete to sink if the concrete is partially supported by soil and other areas are not.
Main Reasons Why Outdoor Concrete Begins to Crack and Sink
Depending on the type of soil, will determine the load capacity. Soil begins to settle and compact when the capacity of the soil is exceeded. Naturally, soil can compact and settle on its own over time, sometimes as little as under a year. Soil will shrink substantially if it becomes dry or contains large amounts of a clay because clay can become elastic. Soils rich in clay can contract and expand with moisture. Clay loses strength and becomes elastic from being in contact with water causing the concrete to sink. The types of moisture that can cause this type of damage are leaks from plumbing, snow melting, or heavy rain. Soil may become washed away which may be supporting concrete if water begins to move underneath the concrete causing voids, or empty spaces underneath the concrete. Concrete will begin to sink and crack in several spots if the soil is compacted underneath the concrete. Soil may not be able to provide adequate support of concrete under concrete steps, driveways, or patios. This causes concrete to begin to sink overtime with nothing underneath to support it. Poor drainage causes instability in soil allowing concrete to settle by creating saturated areas in the soil. Improper compaction of soil can also cause damage in concrete. Most homes are built on soils that are backfilled. Backfill will compact slowly and evenly if the soil is not compacted properly allowing the concrete to begin to settle. Tree roots and large shrubs intake over 30 gallons of water daily. Concrete scan settle if water loss happens in the soil causing the soil to contract near the concrete.
