Concrete Lifting & Leveling in Durham, NC

Common Causes of your Concrete Problems in Durham

Poor Soil Compaction

The soil beneath the concrete may not have been compacted enough during construction. Over time, the loose soil shifts and settles, causing the concrete to sink or crack.

Soil Erosion

Water from rain, sprinklers, or poor drainage can wash away the soil under the slab. This creates empty spaces, making the concrete sink or become uneven.

Climate Conditions

When saturated, clay soil expands, and when dry, it contracts. These constant changes in moisture levels weaken the support beneath the concrete.

Freeze-Thaw Cycles

Water in the soil freezes and expands during winter, then thaws and contracts. This movement puts pressure on the concrete, leading to cracks or lifting over time.

Tree Roots

Roots from nearby trees or shrubs can grow underneath concrete. As they grow, they push up on the slab, causing uneven surfaces or cracks.

Heavy Loads

Parking heavy vehicles or placing large items on concrete can compact the soil underneath. Weak soil cannot often support the weight, causing the slab to sink or crack.

Poor Drainage

Excessive rainwater or water pooling near concrete slabs can lead to soil washout, weakening the soil under the concrete.
