How To Fix Foundation Damage In Lappe, ON

A solid foundation is crucial for the structural integrity and safety of your home. Over time, various factors can cause foundation issues that, if left untreated, can lead to severe structural damage. At Northwest Drainage Solutions, we specialize in providing expert foundation repair services in Lappe, ON. Our experienced team is dedicated to ensuring your home remains safe and stable.

Common Causes of Foundation Problems

Soil Issues:

Soil composition plays a significant role in the health of your foundation. In Lappe, the expansion and contraction of clay soil, poor soil compaction, and soil erosion are common culprits behind foundation issues. These soil movements can lead to significant stress on your foundation, causing cracks and shifts.

Water Damage:

Excess moisture is a major enemy of foundations. Poor drainage, plumbing leaks, and heavy rainfall can all contribute to water accumulation around your foundation, weakening the structure and causing it to settle unevenly.

Structural Overload:

Adding excessive weight to your home’s foundation, whether through home additions or nearby construction, can lead to foundation overload. This stress can cause the foundation to crack and settle.

Natural Disasters:

Lappe experiences its share of natural disasters such as floods, severe storms, and even occasional earthquakes. These events can have a devastating impact on the foundation, necessitating immediate repair to prevent further damage.

Signs Your Foundation Needs Repair

Cracks in Walls and Floors:

Cracks are one of the most visible signs of foundation issues. Horizontal, vertical, or diagonal cracks in your walls and floors can indicate foundation settlement or movement.

Uneven or Sloping Floors:

If you notice your floors are no longer level, this could be a sign of foundation problems. Uneven floors can result from the foundation settling or shifting.

Sticking Doors and Windows:

Doors and windows that suddenly become difficult to open or close are often a sign of foundation movement. This issue occurs because the frames are no longer square due to the foundation shifting.

Gaps Around Window and Door Frames:

Noticeable gaps around window and door frames can indicate that your foundation is moving. These gaps can allow moisture and pests to enter your home, exacerbating the problem.

Our Foundation Repair Services

Comprehensive Foundation Inspection:

At Northwest Drainage Solutions, we begin with a thorough inspection to identify the root cause of your foundation problems. We use advanced technology to ensure an accurate assessment, which is crucial for developing an effective repair strategy.


Underpinning involves strengthening and stabilizing your foundation. We use different methods such as piering and piling to provide the necessary support. This process is essential for homes with significant foundation settlement or instability.

Slab Jacking:

Slab jacking, also known as mudjacking, is a minimally invasive method used to lift and level sunken concrete foundations. This technique involves injecting a mixture of sand, cement, and water beneath the foundation to raise it back to its original position.

Crack Injection:

For foundation cracks, we use epoxy and polyurethane injections to seal them and prevent water infiltration. This method not only stops leaks but also reinforces the structural integrity of your foundation.


To protect your foundation from moisture damage, we offer both exterior and interior waterproofing solutions. These techniques include applying waterproof coatings, installing drainage systems, and using vapor barriers to keep your foundation dry.

Cost Considerations for Foundation Repair

Factors Influencing Costs: The cost of foundation repair depends on several factors, including the extent of the damage, the repair method chosen, and the size and type of foundation. Understanding these factors can help you plan and budget for the necessary repairs.

Average Cost Ranges:

  • Crack Injection: $300 - $800 per crack
  • Slab Jacking: $1,000 - $3,000
  • Underpinning: $2,000 - $10,000 per pier
  • Waterproofing: $1,000 - $5,000

Budgeting Tips: Planning for foundation repair expenses involves setting aside funds for immediate repairs and ongoing maintenance. Explore financing options and consider the long-term savings from timely repairs to manage costs effectively.

DIY vs. Professional Foundation Repair

DIY Repairs:

Pros: DIY repairs can save money and provide a sense of accomplishment.

Cons: DIY repairs carry risks, such as improper application, lack of specialized tools, and potential for further damage. They may also lack the durability of professional repairs.

Professional Repairs:

Pros: Professional repairs offer expertise, quality materials, and guaranteed results. Professionals can identify underlying issues and provide comprehensive solutions.

Cons: Higher upfront costs compared to DIY solutions. However, the long-term benefits and durability often justify the investment.

Preventive Maintenance Tips to Protect Your Foundation

Regular Inspections:

Conduct regular inspections of your foundation to identify potential issues early. Look for cracks, uneven floors, and other signs of foundation movement. Early detection can prevent minor problems from becoming major repairs.

Proper Drainage:

Ensure your home has effective drainage systems to prevent water from pooling around your foundation. This includes maintaining gutters, downspouts, and ensuring proper grading away from your home.

Soil Management:

Maintain proper soil moisture levels around your foundation to prevent soil expansion and contraction. This can involve installing a watering system to keep the soil consistent during dry periods.

Tree and Shrub Management:

Plant trees and shrubs at a safe distance from your home to prevent their roots from interfering with your foundation. Roots can cause significant damage by absorbing moisture from the soil and creating pressure against your foundation.
