Wall Crack Repair in St. Louis: Epoxy Injection & Carbon Fiber Reinforcement
Do You Have Foundation Cracks?
Cracks in your basement wall aren’t just cosmetic—they can invite water and signal stress in your foundation. Perma Jack of St. Louis specializes in Wall Crack Repair that stops leaks and restores strength using two proven solutions: Epoxy Injection Crack Repair and carbon fiber reinforcement. No pressure, no upsells—just the right fix for your home.
Do You Need Foundation Crack Repair?
If you’re seeing any of the following, it’s time to have a pro look:
- Damp or dripping cracks after rain (Leaky Wall Crack Repair)
- Hairline cracks that are widening or spreading
- Stair-step cracks in block walls or Horizontal Foundation Cracks
- Efflorescence (white powder), musty odors, or peeling paint near cracks
- Sticking doors/windows or new drywall cracks near the basement
Catching foundation cracks early helps prevent structural movement and keeps your basement dry.
Our Repair Methods
Epoxy Injection Crack Repair
Epoxy Crack Injection is ideal for most poured concrete wall cracks that leak or need structural bonding.
What we do:
- Inspect & prep – We evaluate crack type, width, and any wall movement, then clean and place injection ports.
- Surface seal – A temporary paste keeps epoxy inside the crack path.
- Pressure inject – From the bottom up, we inject structural epoxy to fill the crack through its full depth.
- Cure & bond – As epoxy cures, it chemically bonds the concrete, restoring continuity and sealing water entry.
Carbon Fiber Reinforcement
When cracking is tied to wall movement—or when we see Horizontal Foundation Cracks—we often pair epoxy with carbon fiber reinforcement. Slim, high-strength carbon fiber straps or staples are epoxied to the wall to resist inward soil pressure and reduce the risk of future movement.
Best for:
- Horizontal or stair-step cracks indicating lateral pressure
- Areas with recurring cracks
- Strengthening targeted sections without excavation or bulky hardware
Epoxy vs. Carbon Fiber: Which Fix Is Right?
Leak only, no movement?
We will recommend Epoxy Injection Crack Repair to seal and bond the crack.
Crack with signs of movement or a horizontal crack?
Our team will add carbon fiber reinforcement (often with epoxy) for strength.
Not sure?
We’ll inspect, explain, and recommend the simplest effective repair.
FAQs About Foundation Cracks
Are foundation cracks normal?
Is epoxy injection permanent?
What about horizontal foundation cracks?
Horizontal Foundation Cracks often indicate lateral pressure and should be addressed promptly—typically with carbon fiber reinforcement and, if needed, epoxy.
Can I use a DIY kit?
Store kits rarely achieve full-depth penetration or address movement. Professional Foundation Crack Repair ensures proper prep, full injection, and reinforcement where necessary.
