Sinking Concrete Repair

Sinking concrete refers to the gradual downward movement or settling of concrete surfaces, such as sidewalks, driveways, patios, or foundations. It occurs when the soil beneath the concrete becomes unstable or undergoes changes that cause the concrete to sink or become uneven.

Causes of Sinking Concrete:

1

Soil Erosion: When water runoff or poor drainage erodes the soil beneath the concrete, it creates voids or empty spaces. As the soil loses its support, the concrete above it sinks into these gaps.

2

Poor Soil Compaction: Inadequate compaction during the initial construction phase can lead to settling over time. If the soil beneath the concrete was not properly compacted, it may compress or shift, causing the concrete to sink.

3

Soil Consolidation: Certain types of soil, such as clay, can undergo consolidation or shrinkage due to changes in moisture content. This consolidation can cause the concrete to sink as the soil beneath it compresses.

4

Foundation Replacement: In severe cases where the foundation damage is extensive or beyond repair, complete foundation replacement may be necessary.

Signs of Sinking Concrete

Uneven Surfaces: Sunken concrete surfaces often exhibit noticeable slopes, dips, or unevenness. This can create tripping hazards and affect the aesthetics of the area.
Cracks: Sinking concrete may result in cracks forming on the surface. These cracks can be small and hairline or larger and more significant, depending on the extent of the settlement.
Water Pooling: When concrete sinks, it can create low spots where water collects or puddles form, indicating improper drainage.
Separation: In some cases, sinking concrete can separate from adjacent structures, such as buildings or curbs, creating gaps or spaces between them.
Structural Problems: In severe cases, sinking concrete can impact the structural integrity of buildings or foundations, leading to issues such as sloping floors, sticking doors or windows, or cracks in walls.

Fix Sinking Concrete

To address sinking concrete, various repair methods can be employed, such as:

Polyurethane Foam Injection: Injecting expanding polyurethane foam beneath the concrete to fill voids, raise the slab, and provide stabilization.
Mudjacking: Injecting a slurry mixture of cement, soil, and other materials beneath the concrete to lift and level the surface.
Replacement: In cases where the damage is extensive or the concrete is beyond repair, complete replacement may be necessary.
