How to Fix Foundation Cracks

Maintaining a secure and stable home is a task that demands ongoing attention, especially when it comes to the structural integrity of your foundation. The ability to effectively fix foundation cracks is crucial.

As time passes, even the most durable foundations are susceptible to the formation of cracks due to various factors. If these cracks are neglected, they could lead to severe implications for your home’s stability and safety.

What Causes Foundation Cracks?

Determining the root cause of a foundation crack can help with the best repair method. Various factors can contribute to the development of foundation cracks, which may vary from natural environmental changes to human-made construction errors.

• Soil Settlement
  Over time, the soil beneath your home may settle or compact due to the weight of your property. This settlement can unevenly distribute the weight of your building, putting excessive stress on certain parts of the foundation and resulting in cracks.
• Hydrostatic Pressure
  This occurs when water builds up in the soil surrounding your foundation. The increased pressure pushes against the foundation walls, causing them to crack or buckle.
• Temperature Fluctuations
  As seasons change, the concrete in your foundation expands and contracts in response to changes in temperature. These fluctuations can lead to cracks over time, particularly if the temperature changes are sudden or extreme.
• Construction Errors
  Sometimes, mistakes during the construction process can lead to foundation cracks. For example, if the concrete was not allowed to cure properly or if an inadequate amount of steel was used in the foundation’s construction, cracks could develop.

By understanding causes, we are better equipped to identify the right solutions to fix foundation cracks. It also enables homeowners to take preventive measures and respond promptly when cracks first appear, mitigating further damage and maintaining the safety and integrity of their homes.

Types of Foundation Cracks

Not all foundation cracks are the same. The type of crack can provide clues about its cause, potential for damage, and the best method to repair it.

One common type of foundation crack is the vertical, or hairline, crack. These cracks usually run straight up and down or slightly diagonal and are not wider than 1/8 inch. Though they may seem small, ignoring these hairline cracks can lead to severe problems, including:

• Water Leakage and Basement Flooding
  Hairline foundation cracks can allow water to enter your basement or crawl space, leading to dampness, mold growth, and potential basement flooding during heavy rainfalls or when the water table rises.
• Pest Infestation
  These cracks can serve as gateways for pests such as ants, termites, rodents, and insects to infiltrate your home. This can result in structural damage, particularly if wood-eating pests gain access.
• Decreased Energy Efficiency
  Cracks in the foundation can lead to drafts and permit the escape of conditioned air. This can significantly impact your home’s energy efficiency, leading to higher heating and cooling costs.

Fixing Cracks with Resin Injection

Resin injection is an increasingly popular method to fix foundation cracks, and for a good reason. It’s efficient, non-invasive, and offers a long-lasting solution. Below is step-by-step on how the process works:

1. Crack Preparation
   Before the resin injection, the crack is thoroughly cleaned to ensure that the resin will adhere properly. This usually involves removing any loose debris, dust, and contaminants.
2. Crack Sealing
   Small ports are installed along the length of the crack. These ports, often made of plastic or metal, are designed to allow the resin to be injected directly into the crack.
3. Resin Injection
   The resin is then injected into the crack through the ports. Once injected, the resin expands and solidifies, effectively sealing the crack. This creates a durable and watertight seal that protects your foundation from further damage.

While resin injection offers a robust solution for fixing foundation cracks, it demands the expertise and precision of seasoned professionals. Our team at Crackmasters is equipped with these skills and ready to help. Don’t hesitate to reach out to us for a quote today.

The Advantages of Resin Injection

Resin injection provides several benefits over traditional repair methods. This has made it a favoured choice among homeowners and repair professionals. Some key advantages:

• Water and Moisture Resistance
  The resin forms a watertight seal once it has cured, effectively blocking water infiltration. This reduces the potential for water damage and the growth of mold and mildew within your home.
• Excellent Flexibility
  Unlike some materials used in foundation repairs, resin maintains its flexibility after curing. This means it can better accommodate minor movements and vibrations within the building structure without cracking again, making it an ideal solution for fixing foundation cracks caused by soil settlement or slight structural shifts.
• Cost-Effectiveness
  Compared to methods such as external waterproofing or total foundation replacement, resin injection is often more cost-effective. The process is quicker, requires less labor, and doesn’t necessitate significant excavation.
• Minimal Disruption
  Given that the resin injection process is conducted internally, there’s minimal disturbance to your home’s external landscape. This makes it an attractive choice for homeowners who’ve invested in landscaping or hardscaping that they’d prefer not to disturb.
• Long-Lasting Results
  Resin injections are designed to provide a durable and resilient barrier against future cracking. This means fewer worries about recurrent foundation issues and costly repeat repairs.

Understanding how to fix foundation cracks is crucial to maintaining the structural integrity and safety of your home. If you notice signs of foundation cracks, early intervention can save you from larger, more expensive repairs down the line.

It’s always best to engage professionals who have the necessary experience, skills, and equipment to correctly assess and fix foundation cracks. Reach out to Crackmasters for a home foundation assessment and secure the stability of your home for years to come.
