What "specialized" actually means for foundation crack repair at our company — not a marketing word, a set of specific practices.
We don't inject resin into a crack that's still actively widening — that's a band-aid, not a fix, and we'll tell you so directly.
Trucks carry both epoxy and polyurethane injection systems so the crew can match the resin to the crack type on the first visit.
No hourly billing surprises — if a crack turns out longer or more complex once opened up, we discuss it with you before proceeding, not after the invoice arrives.
Epoxy resin, which cures rigid and restores structural bond strength, is reserved for stable, non-water cracks needing load-bearing repair.
Each service below is scoped specifically to foundation crack repair, not a generic waterproofing menu with the name swapped in.
For cracks actively passing water, polyurethane injection resin is pumped in under pressure, where it expands to fill the full depth and width of the crack, including hairline branches a surface patch would miss.
This method is reserved for cracks confirmed as non-active — injecting epoxy into a still-moving crack just cracks the epoxy itself.
Stair-step cracking in block or brick foundation walls typically signals soil pressure or settlement issues beyond what injection alone resolves.
This is a specialized repair beyond simple crack injection, and we walk you through the engineering rationale before recommending it.
We evaluate downspout extensions, soil slope, and window well drainage as part of a complete crack repair, not an afterthought.
Here's what happens between your call and a resolved foundation crack.
Photos texted ahead of the visit help the technician arrive with a working hypothesis on crack classification.
Most Hillsboro, IL crack evaluations are scheduled within a few days for non-emergency cases, faster for active leaks.
You'll see the classification explained in plain terms — why this crack is a polyurethane candidate versus needing a structural referral.
If evaluation during the visit reveals the crack needs engineering review instead of injection, we'll tell you plainly rather than injecting a crack that shouldn't be injected.
