Common Culprits Behind Concrete Foundation Cracks

1. Soil Movement & Settlement

Over time, the soil beneath your foundation shifts. This can create uneven pressure on the walls of your foundation and lead to cracks. Soil movement is due to several issues:

• Soil Types: Some areas have expansive soils that expand and contract when wet and dry. This creates constant pressure on the foundation and can lead to weaknesses.
• Erosion: Improper drainage can wear away the soil around your foundation and cause your home to settle unevenly.
• Poor Compaction: If the soil is adequately compacted during construction, it will be strong and move over time.

2. Water Damage

Water is the archnemesis of concrete foundations. As a homeowner, you will experience a constant battle to keep water from damaging your home. Familiar sources of water damage around your foundation include poor drainage, plumbing leaks, and flooding.

• Poor Drainage: Bad water systems allow water to pool around your home's foundation, leading to increased hydrostatic pressure.
• Plumbing Leaks: A leaky pipe near the foundation can weaken the concrete and cause cracks.
• Flooding: Although uncommon, natural disasters and heavy rainfall can cause cracks in the foundation from water intrusion and subsequent damage.

3. Temperature Swings

Temperature fluctuations can cause the concrete to expand and contract as seasons change. If not managed, this natural movement can weaken the concrete and cause cracks.

4. Tree Roots and Plant Life

Tree roots are firm and resilient. If trees are planted near your foundation, their roots can grow into the concrete and create cracks. This is because roots absorb water from the soil, leading to shrinkage and increased soil settling.

How to Fix a Foundation Crack?

If you notice a crack in your foundation, it's crucial to act swiftly to prevent further damage. Delaying the repair process can lead to more significant issues, potentially compromising the safety and stability of your home.

Our professional team will inspect your property and assess the extent of the damage. We will identify the underlying causes and recommend rebuilding a solid foundation.

Foundation Repair Solutions

Based on the inspection, several proven and effective foundation repair solutions may be recommended, including:

• Crack Injection: This method involves injecting a specialized epoxy or polyurethane material into the cracks. This material then expands and hardens, sealing the cracks and preventing water infiltration.
• Underpinning: This technique involves strengthening the foundation by extending it to more stable soil layers.
• Drainage Improvements: Improving the drainage system around your home can help prevent water from accumulating around the foundation.

Preventative Measures

Preventative measures can help avoid future foundation cracks, such as:

• Proper Landscaping: Ensure trees and shrubs are planted safely from the foundation to prevent root interference.
• Regular Maintenance: Inspect and maintain your home's drainage systems to prevent water damage.
• Soil Management: Managing the moisture content of the soil around your foundation by ensuring it's not too dry or too wet can help prevent soil movement and settlement.
