If you own a home in Maine, you know how harsh winters and shifting soil can cause foundation cracks. These cracks might seem small, but they can lead to serious issues like water leaks, mold growth, and even structural damage. In this guide, we’ll explain why foundation cracks happen, how they can impact your home, and the best way to fix them permanently.
Why Do Foundation Cracks Happen? Maine’s climate is tough on concrete. Here are the main reasons foundation cracks appear:
- Freeze/Thaw Cycles: Water seeps into small cracks, freezes, and expands, making cracks larger over time.
- Soil Movement: As the ground shifts due to moisture changes, foundations can settle unevenly.
- Poor Concrete Mixing: If concrete wasn’t mixed or poured correctly, weak spots can develop over time.
- Heavy Loads & Vibrations: Nearby construction, heavy vehicles, or even natural events like earthquakes can contribute to cracking.
The Risks of Ignoring Foundation Cracks A small crack today can lead to serious problems down the road. Here are some of the biggest risks:
- Water Leaks: Cracks allow moisture to seep in, causing damp basements, mold growth, and potential flooding.
- Radon Gas Intrusion: Radon, a naturally occurring gas, can enter through foundation cracks, posing health risks.
- Pest Infestations: Small cracks create openings for insects and rodents to enter your home.
- Structural Weakness: Over time, cracks can compromise the foundation’s strength, leading to costly repairs.
The Best Solution: Epoxy & Polyurethane Injection At Concrete Prescriptions, we use epoxy and polyurethane injection to seal foundation cracks permanently. Here’s how the process works:
- Crack Inspection: We assess the damage and determine the best repair approach.
- Injection Ports Installation: Small ports are placed along the crack for even material distribution.
- Surface Sealing: A temporary seal is applied to keep the injection material inside the crack.
- Injection Process: Epoxy or polyurethane is injected into the crack, filling it completely.
- Curing & Final Sealing: The material hardens, creating a waterproof and structural bond.
