Effective Techniques for Foundation Crack Repair in Long Island

Spotting a foundation crack in your Long Island home can be alarming. However, with the right techniques, these issues can be effectively repaired to restore structural integrity and avoid further damage. 

Let’s explore some of the best methods for foundation crack repair in Long Island:

  • Epoxy Injection: This popular technique is ideal for non-structural cracks. Epoxy resin is injected under pressure, filling the crack completely and creating a watertight seal while strengthening the foundation.
  • Polyurethane Injection:  For actively leaking cracks, flexible polyurethane foam is injected. The foam expands to fill voids and provides a waterproof barrier, preventing further water intrusion into your home.
  • Steel Piers: In cases of significant settlement or shifting, steel piers are driven deep into stable soil layers to provide support and potentially lift the foundation back into position.
  • Carbon Fiber Reinforcement:  Carbon fiber strips offer a less invasive solution for strengthening foundation walls, minimizing further cracking and adding stability.

The Importance of Professional Assessment

The most effective repair technique depends on the type of crack, its severity, and the underlying cause.  That’s why a professional foundation assessment is crucial. Our Long Island team’s expertise ensures the correct approach is used, providing long-lasting solutions.
