Foundation Crack Repair 

—————————————————————

Introduction

Ottawa’s harsh climate, characterized by freezing winters, stresses residential and commercial foundations significantly. This stress can lead to cracks that, if left unaddressed, may compromise the structural integrity of your property. Immediate attention is crucial when water begins to enter through basement floors or walls. Our masons are experts in foundation crack repair services and are able to ensure that your home remains safe, secure, and stable.

Why Foundation Cracks Occur

Foundation cracks can result from various factors. Understanding these causes helps prevent and address the issues effectively.

• Freeze-Thaw Cycles
  • Soil Expansion and Contraction: Water in the soil freezes and expands, exerting pressure on the foundation.
  • Repeated Stress: Continuous freeze-thaw cycles weaken the foundation over time.
• Settling and Shifting
  • Natural Settling: Over time, buildings naturally settle, which can create minor to significant cracks.
  • Poor Soil Compaction: Inadequate soil preparation before construction leads to uneven settling.
  • Tree Root Growth: Roots can disrupt soil stability, causing the foundation to shift.
• Hydrostatic Pressure
  • Water-Saturated Soil: Excess water around the foundation increases pressure against walls.
  • Inadequate Drainage: Poor drainage systems allow water to accumulate near the foundation.
• Construction Flaws
  • Improper Reinforcement: Lack of adequate reinforcement during construction makes foundations more susceptible to cracking.
  • Use of Substandard Materials: Inferior materials can fail under stress, leading to cracks.
• External Factors
  • Seismic Activity: Although rare in Ottawa, any ground movement can impact the foundation.
  • Vibrations from Nearby Construction: Heavy machinery and construction activities can induce stress on existing foundations.

Types of Foundation Cracks

Different types of cracks indicate various underlying issues. Identifying the type helps determine the appropriate repair method.

• Vertical Cracks
  • Description: Straight, vertical lines appear on foundation walls.
  • Causes: Settling or shrinking of concrete, minor soil movement.
  • Implications: Generally less severe but require monitoring and repair to prevent escalation.
• Horizontal Cracks
  • Description: Cracks that run parallel to the ground.
  • Causes: Significant hydrostatic pressure from water-saturated soil or expansive clay.
  • Implications: More severe as they indicate greater structural stress and potential for water intrusion.
• Diagonal Cracks
  • Description: Slanted cracks that can run in any direction.
  • Causes: Differential settling is when one part of the foundation settles more than another.
  • Implications: This can indicate uneven foundation support and the potential for further structural issues.
• Step Cracks
  • Description: Stair-step pattern cracks are typically found in block or brick foundations.
  • Causes: Natural settling along the mortar joints.
  • Implications: Common in older homes; requires assessment to ensure stability.
• Hairline Cracks
  • Description: Very thin horizontal or vertical cracks, barely visible from a distance.
  • Causes: Minor settling or temperature changes.
  • Implications: Often cosmetic but should be monitored for any progression.

Our Crack Repair Process

Our comprehensive foundation crack repair process ensures effective and long-lasting solutions.

1. Inspection
   • Thorough Assessment: Detailed examination of the foundation to identify all existing cracks and their causes.
   • Moisture Detection: Using advanced tools to detect moisture ingress and assess waterproofing needs.
   • Soil Analysis: Evaluating soil conditions around the foundation to determine underlying issues.
2. Crack Cleaning and Preparation
   • Debris Removal: Clearing out dirt, debris, and old repair materials from the cracks.
   • Surface Preparation: Ensuring the crack surfaces are clean and dry for optimal repair material adhesion.
   • Drying Process: Using dehumidifiers and fans to eliminate moisture from the affected areas.
3. Epoxy or Polyurethane Injection
   • Material Selection: Choosing the appropriate injection material based on crack type and severity.
   • Sealing the Crack: Injecting epoxy or polyurethane to seal the crack and prevent water ingress.
   • Curing Time: Properly allowing the injected materials to cure ensures a durable seal.
4. Reinforcement
   • Structural Support: Installing reinforcements such as steel bars or carbon fiber strips to strengthen the foundation.
   • Preventative Measures: Applying additional support to areas prone to future cracking.
   • Final Inspection: Ensuring that the reinforced areas meet structural integrity standards.
5. Additional Services
   • Sealing Wall Cracks and Pipe Penetrations: Ensuring all potential entry points for water are sealed.
   • Fixing Leaky Floor Cracks: Addressing cracks that allow water to seep through floors.
   • Stopping Flooding Through Windows: Implementing solutions to prevent water intrusion around window areas.

Signs You Need Foundation Crack Repair

Recognizing the warning signs early can prevent extensive damage and costly repairs to foundation problems.

• Visible Cracks in Basement Walls or Floors
  • Size and Pattern: Noticeable cracks that are widening or changing over time.
  • Location: Cracks near doors, windows, or where pipes penetrate the foundation.
• Water Leakage Through Cracks
  • Dampness: Persistent moisture or water stains around cracks.
  • Mold Growth: The presence of mould or mildew indicates ongoing moisture issues.
• Doors and Windows That Stick or Won’t Close Properly
  • Alignment Issues: Difficulty in opening or closing doors and windows due to foundation movement.
  • Frame Damage: Warped or misaligned frames caused by shifting foundations.
• Uneven Floors
  • Sloping or Sagging: Floors no longer level create an uneven walking surface.
  • Gaps and Bumps: Gaps between flooring and walls or noticeable bumps indicating structural shifts.
• Exterior Signs
  • Cracked Exterior Walls: Visible cracks on your home’s exterior walls often indicate a structural problem with a foundation.
  • Gaps Around Siding: Spaces between the siding and foundation allow pests and moisture to enter.
