🔄 Our Proven Concrete Crack Injection Process

Koomen Contracting uses a precise, effective workflow to ensure long-lasting protection:

1. On-Site Crack Assessment
   We inspect all visible cracks and leak points to determine cause, depth, and best sealing method.
2. Preparation & Port Installation
   Injection ports are installed along the crack path and the surface is sealed for resin containment.
3. High-Pressure Resin Injection
   Polyurethane resin is injected under pressure to penetrate the full crack depth and expand for a watertight seal.
4. Curing & Clean-Up
   The resin cures in minutes, forming a flexible, durable seal. We then remove ports and clean the workspace.
5. Final Walkthrough & Maintenance Tips
   We review results with you and provide optional waterproofing or drainage recommendations if needed.
