We classify every crack before injecting it — structural cracks get epoxy, active leaks get flexible polyurethane, and both get a written scope before we start.
Not every Riva, MD foundation crack needs the same material or approach. A vertical settlement crack behaves differently than a stair-step block crack, and we adjust injection technique and material to match what's actually happening in the wall.
Misclassifying a crack is the most common mistake in this trade, and it's the first thing we check on every Riva, MD job.
Most crack injection appointments can be scheduled within a day or two of your call.
Pricing is based on crack length and injection material, quoted in writing before we drill any injection ports.
We carry both structural epoxy and flexible polyurethane so the crew can match material to the crack on the same visit.
Every Riva, MD Foundation Crack Repair job starts with an inspection, not a generic package — here's what that typically includes.
Epoxy-injected cracks regain much of their original structural strength, which matters for load-bearing foundation walls.
Polyurethane cures even in the presence of water, which makes it the right call for a crack that's actively letting water through.
Stair-step cracking in block foundation walls needs a different injection port pattern than a vertical crack in poured concrete, and we adjust technique accordingly.
Vertical cracks are usually settlement-related and often isolated; horizontal cracks can indicate hydrostatic pressure pushing on the wall and get flagged for further evaluation.
Fast turnaround matters during a real estate transaction, and we prioritize scheduling for time-sensitive pre-sale repairs.
Photos texted ahead of time help us prep for the visit and sometimes speed up scheduling.
A technician measures crack width, checks for wall bowing, and determines whether it's structural, cosmetic, or actively leaking.
We explain why we're recommending one material over the other so the choice isn't a black box.
Most single-crack injections are completed in a few hours, start to finish, in one visit.
"Crack in our basement wall had been leaking for a year before we finally called. Injection took less than an afternoon and it's been dry since."
— Riva Seller
"Polyurethane injection stopped an active leak the same day they showed up — didn't expect it to be that fast."
— Riva Homeowner
"Appreciated the before-and-after photos for our records in case we ever need them for a future sale."
— Riva Customer
"Stair-step crack in our block wall had us worried about the whole foundation. Turned out to be isolated and fixable with injection."
— Riva Homeowner
Active leaks get flexible polyurethane regardless of classification, since stopping water intrusion is the immediate priority.
We repair cracks of nearly any size — hairline cracks are often the easiest and cheapest to seal before they widen further.
Epoxy is better for structural bonding on a non-leaking crack; polyurethane is better for a crack that's actively weeping since it cures even with water present.
Multiple cracks or hard-to-access areas can extend the timeline, which we'll flag in the written quote.
A properly injected crack is unlikely to reopen at the same spot, and our work comes with a written warranty covering exactly that.
