Foundation Crack Injection in Holliston, MA

Licensed foundation crack injection in Holliston

Need foundation crack injection in Holliston, MA? Concrete Solutions LLC is a licensed, insured contractor serving Holliston, Medway, Millis, and the rest of Middlesex County. We've handled concrete, masonry, and waterproofing across MetroWest and Norfolk County since 1995, with free written estimates, fair pricing, and a workmanship guarantee.

Foundation crack injection is the fastest, least invasive way to permanently seal a cracked poured-concrete foundation wall. Instead of excavating the outside of the home, we inject a resin directly into the crack from the interior, filling it through the full thickness of the wall. The right resin depends on the crack: rigid epoxy for structural, dry cracks that need the wall's strength restored, and flexible polyurethane for active leaks where the crack still moves with seasonal or hydrostatic pressure.

Method & materials

How we approach foundation crack injection

Low-viscosity structural epoxy for dry, hairline-to-1/4" cracks that need the wall's load-bearing strength restored, cures rigid and stronger than the concrete around it.
Expanding hydrophobic polyurethane for active water leaks, it reacts with moisture, foams to fill irregular voids, and stays flexible so it moves with the crack instead of re-cracking.
Surface ports set every 6-8 inches with a paste-over cap so resin is injected under pressure through the full wall thickness, not just the visible face.
For structural cracks caused by ongoing movement, carbon-fiber strapping can be added so the wall is stabilized, not just sealed.

What goes wrong when it's done cheap

  • Caulk or hydraulic cement smeared on the surface only bridges the face; water tracks behind it and the crack keeps leaking within a season.
  • Using rigid epoxy on an actively moving or wet crack, it can't bond to damp concrete and cracks again at the next freeze-thaw cycle.
  • Injecting only the visible portion instead of the full wall depth, leaving an unsealed path on the exterior side.

Do I need a permit for foundation crack injection in Holliston?
It depends on scope. Some foundation crack injection work is a straightforward repair that doesn't need a permit; larger or structural scopes can. When a permit is needed, we pull it with the Holliston Building Department on your behalf.
Epoxy or polyurethane, which does my crack need?
If the crack is dry and structural, we use rigid epoxy to restore the wall's strength. If it actively leaks or still moves with the seasons, we use flexible polyurethane that seals under pressure and flexes instead of re-cracking. We decide on-site based on whether the crack is wet and whether it's still moving.
Do you have to dig up my yard to fix a foundation crack?
No. Crack injection is done entirely from inside the basement, we inject resin through the full thickness of the wall from the interior. Excavation is only needed for a different class of problem, like replacing a failed wall section or full exterior waterproofing.
Is an injected crack permanent, or will it come back?
The resin cures inside the crack and bonds to the concrete, so the crack itself is sealed for good. What matters is treating the cause, if the crack is from ongoing wall movement, we add carbon-fiber reinforcement so it doesn't reopen next to the repair.
