How do you determine for yourself whether your foundation crack is serious or nothing to worry about? Here are some things to look for when determining whether your foundation cracks are serious:. Size: The wider the crack, the more dramatic the foundation settlement or shift. Number: The more cracks that occur in your foundation, the weaker your foundation may be. Location: Stair-step cracks and vertical cracks that appear in the southern corners of your home typically indicate foundation movement.
If you notice the following concerns around your home, especially if in conjunction with foundation cracks, you should call a contractor to review your home for foundation failure:.
Though each type of foundation crack has unique causes, here is a summary of the most common causes of foundation cracks:. Repairing foundation cracks is often a more extensive process than just sealing cracks with an epoxy injection, as this only addresses the cosmetic and leaking concerns.
Cracks that occur due to soil pressure, hydrostatic pressure, or settlement need a foundation repair method that fixes the problem at its source. This sometimes requires installing piers, anchors, nails, or piles to stabilize the foundation and soil—preventing foundation failure from recurring. We always aim for maximum closure when we stabilize your foundation, but caulking or remortaring is an option for providing added strength and peace of mind. Though there are many DIY instructions online for how to fix foundation cracks by yourself, we recommend having a foundation repair specialist first look at your home for structural damage before you attempt home repairs.

Yes, I think the cracks are structural and will be a problem in the future. Lee Sam Lee Sam The answers above indicate to me that you back out of the purchase on the grounds that the quality of the foundation is substandard and prone to failure.
Lee Sam, you surely know what recourse is available, but if the slab is supposed to have rebar in certain places and it has only mesh, how can the builder hold a customer to a purchase agreement? They may have installed it. It would be good to have a photo during the concrete pour. Could it be possible they do the mesh first and put the rebars at the time of pouring?

JimStewart The slab could be fiber reinforced, or no reinforcement but it still must be installed with good building practices. We install slabs without mesh or any reinforcement but we recognize good practices by decreasing the spacing of control joints, protect the vapor barrier, etc.
After looking again I would agree that the spacing is two far for the blocking of the mesh but it can be pulled up but is difficult. Ed Beal, so would rebar be required in the thickened edges and in the internal beams of a slab foundation which is otherwise 4" thick? Mesh on the bottom of the slab is the worst place. When the slab begins to cure, it shrinks. The very top will shrink the most because it has the least resistance, while the very bottom will shrink the least because the mesh is there.
This is what creates cracks on the surface. The key is providing the proper amount of steel. Show 5 more comments. First I will say there are 2 types of concrete, type one has cracks and type 2 will crack later. Ed Beal Ed Beal 1. Here are some pictures: Can anyone tell me if this is something I should be concerned about, or is it standard to find these kinds of small cracks in freshly laid concrete? Are any of these cause for concern: Missing chunks of concrete: Fastener not secured to anything: Footprints in shower recess concrete: Edit - Here's a shot of what was in place immediately before the slab went down:.
Improve this question. Looks like a rather sloppy pour. Are there expansion joints in the slab? Also there's no lagging around the pipe where it penetrates the slab bad form! Did they used steel riobar? Did they use rio chairs to hold the steel at the correct depth in the concrete? They did use steel riobar, yes. And I'm not positive but I believe they did use chairs to hold the steel in place.
What they did was before pouring the actual slab they excavated a network of trenches and filled that with concrete, and then had steel bars protruding vertically out from that at regular intervals I'll add a picture of this. My assumption is that they used those vertical bars to secure the riobar in place, though I wasn't onsite at the time to see if that's what they actually did.
DA01 - Sloppy as in "ugly but still functional", or sloppy to the point where the structural integrity has been compromised? I agree that the pour looks bad, but to answer your title question: it depends. Cracking in concrete surfaces can be perfectly normal depending on the type of concrete and climate. Here in Northern Nevada, for example we have two types of concrete: concrete that is cracked, and concrete that is going to crack.

As Worth say, notify the contractor in writing as a future record , and request he excavate the soil in the vicinity of the crack and determine: 1 the depth and extent of the crack; 2 the condition of the soil beneath the foundation in this area to see if it has been properly backfilled and compacted.
