Cracks in poured concrete foundation walls are a common source of basement leaks. Surface patching rarely lasts because it does not seal the full depth of the crack. Homex Builders repairs foundation cracks with professional injection for homeowners across the Bronx, Manhattan, Brooklyn, Queens, Staten Island, Yonkers, Long Island and New Jersey.
We clean and port the crack, then inject epoxy or polyurethane under pressure so it fills the crack from the inside to the outside surface. Epoxy restores structural strength, while flexible polyurethane creates a watertight seal that moves with the wall.
What Our Crack Injection Includes
Our crack injection service includes:
Crack Assessment
Evaluating crack width, movement and moisture to choose the right material.
Epoxy Injection
Structural epoxy that bonds the concrete and restores strength.
Polyurethane Injection
Flexible foam that expands to seal actively leaking cracks.
Crack injection is a fast, low-disruption repair, usually completed in a few hours from inside the basement, without excavation.

Why Choose Homex Builders
Frequently Asked Questions
Yes. Injection fills the crack through the full thickness of the wall, which stops water far more reliably than surface patching.
Epoxy is used when structural strength is needed. Polyurethane is ideal for sealing leaking cracks because it stays flexible.
Most small vertical cracks are not structural. Wide, horizontal or stair-step cracks should be evaluated and may need structural repair.
Pricing depends on the size of the area, the condition of existing materials, access and the materials you choose. We provide a free on-site estimate with a clear scope and price before any work begins.
Crack injection from inside the basement typically does not require a permit. Structural foundation repairs may. We help confirm requirements.
