So, what can you do about it? If caught on time, we can carry out stem wall repair quickly and aggressively. This is what you want to avoid - once things have reached this level, you have a potential life threat on your Auburn foundation and stem walls. Where the soil doesn’t shift significantly, slabs can also be used. Concrete slab structures can usually be repaired by sealing (waterproofing) and mud jacking (leveling). However, at some point, rusting will have extended enough that it will break the concrete completely. Repairing concrete structures is priced at 350 to 20,000 in most cases. The water will in turn conduct electricity, and the tiny - imperceptible - current formed within will progressively degrade both the rebar and the outside of your concrete.Ĭracks tend to be small at first, which makes them look like something that you can ignore until next spring. These pores, in turn, are a good place for tiny amounts of water to collect– either because of a construction flaw or because of general humidity. Sturdy as concrete is, it remains a porous material. There are a couple of traditional repair options used in these cases including: Patching the cracks Epoxy injection/coating Standard Rebar Replacement Rebar Replacement with Epoxy Coating Waterproof Coatings Unfortunately, all of these methods have issues. The rebar is likely to continue rusting, just hidden from view. Many inexperienced contractors are willing to offer an epoxy seal as a quick fix - but this will rarely fix the problem. Unfortunately, the way oxidation works, it can be very hard to stop once the process has started. Slowly but surely, as the rebar continues to disintegrate, cracks will continue until the concrete splits completely. The immediate cause for damage to your stem walls may vary depending on your property’s location, but the root cause does tend to be the same - rebar oxidation.
