Epoxy Floor Crack Injection in Wilmington, NC
Epoxy crack injection repairs structural cracks in concrete by filling them under pressure with low-viscosity epoxy that cures harder than the surrounding concrete. This is not a surface seal — the epoxy penetrates the full depth of the crack and restores the slab's ability to transfer load across the break. It's the right method for cracks in structural slabs, walls, and foundations where the concrete needs to act as one piece again.

How It Works
Our Process for Epoxy Floor Crack Injection
- 1
Crack Mapping
We trace the full length and estimate depth of each crack before deciding if injection is appropriate.
- 2
Port Installation
Injection ports are surface-mounted at intervals along the crack based on the estimated depth and width.
- 3
Crack Sealing
The crack face between ports is sealed with epoxy paste to contain injection pressure inside the crack.
- 4
Epoxy Injection
Low-viscosity epoxy is injected at low pressure starting from the lowest port until epoxy appears at the next.
Wilmington Context
Why this matters in Wilmington
Foundation and slab cracks in Wilmington often originate from soil movement during heavy rainfall and storm surge events. Cracks that open and close seasonally may not be good candidates for rigid epoxy injection — we'll tell you honestly if a different approach fits better.
Straight Talk
About pricing & scope
Cost depends on total crack length, estimated depth, and how many ports the layout requires. Very tight hairline cracks sometimes need a different viscosity epoxy or a longer injection cycle, which affects material and time.
