Why Foundation Cracks Are a Problem
Foundation cracks are more than just cosmetic issues. Even small cracks in your basement walls or floor can allow water and radon gas to enter your home. Maine's freeze-thaw cycles can cause these cracks to grow over time, leading to more serious structural problems.
At Fidelis Mitigation Solutions, we use professional-grade epoxy injection systems to permanently seal foundation cracks and prevent future problems.
Common Types of Foundation Cracks
- Vertical Cracks: Often caused by concrete shrinkage during curing, these are the most common type
- Horizontal Cracks: Usually caused by soil pressure and can indicate structural concerns
- Diagonal Cracks: Often found near corners and openings, typically caused by settling
- Floor Cracks: Allow moisture and radon to seep up from the soil beneath your home
Our Epoxy Injection Process
We use a low-pressure epoxy injection method that completely fills cracks from the inside out:
Crack Assessment
We examine the crack to determine its cause, depth, and the best repair approach.
Surface Preparation
The crack is cleaned and injection ports are installed along its length.
Epoxy Injection
Low-pressure epoxy is injected through the ports, filling the entire crack from front to back.
Curing & Finishing
The epoxy cures to form a bond stronger than the original concrete. Ports are removed for a clean finish.
Benefits of Epoxy Crack Sealing
- Permanently seals cracks against water infiltration
- Blocks radon gas entry points
- Restores structural integrity to your foundation
- Creates a bond stronger than the original concrete
- Non-invasive repair with no excavation needed
Epoxy vs. Other Repair Methods
While there are several ways to address foundation cracks, epoxy injection offers distinct advantages:
- Epoxy: Structural repair that fills the entire crack and restores strength
- Polyurethane: Flexible sealant better suited for actively leaking cracks
- Surface patching: Temporary cosmetic fix that doesn't address the full crack depth
Our technicians will assess your specific situation and recommend the best approach for your foundation.
