Is there a proper footing or spacer needed at the base of new build stairs to prevent cracking, and if so, how can this issue be fixed or prevented from worsening?

Hey everyone! So, we’re not exactly DIY experts over here, but we did move into a new house about 9 months ago and we’ve noticed that the crack at the bottom of our front steps seems to be growing bigger every day. Does anyone know if there should be some kind of footing or spacer at the base to keep this from happening? And if so, was it poured incorrectly in the first place? Any ideas on how we could fix this or stop it from getting worse? Thanks in advance!
You can probably thank subsidence for that sagging concrete slab. A quick fix would be to hire a company to pump filler underneath to prevent further sinking and then fill the crack. It’s a simple but effective and affordable solution. Just cover it up with a deck!
It would be wise to have an expansion joint in place there.
Seeing that kind of cracking just 9 months after installation is definitely not standard. There could be several reasons behind the cracking, but ultimately they all point to an improper pour and lack of preparation.
For a new build, it’s probable that the ground is settling. Before laying the slab, the soil might not have been compacted well or there could be a leaking gutter drain pipe underneath causing the ground to sink. I’ve personally encountered all three scenarios haha
So I’d follow ‘s advice promptly before the situation escalates because it sounds like settling ground.
Two truths in life.. we pay taxes, and concrete cracks.
Seriously, ALL concrete cracks. But hey, as long as it’s not a huge gap, there’s really nothing to fret about. Treat yourself to a Snickers or binge-watch TV and just chill. 😀
This isn’t just cracking, it’s actually sinking. That’s definitely a problem.
When it comes to a new build, how long does your warranty last? Chances are the ground wasn’t compacted correctly and there might not be any steel reinforcement in the concrete. This crack is likely to worsen over time, so I’d recommend asking the builder to come fix it before the warranty expires.
In my opinion, there should’ve been a control joint at the steps. The steps should’ve been made of different concrete pieces. Concrete tends to shift. Especially if you’re in a cold region. That’s just the way it is unless everything is properly segmented. I’d suggest getting it professionally cut at the step by a concrete expert and maybe even replace the flat section.
Alright, thanks everyone! I’ll talk to the builder to see if we can get it resolved.
Step back a bit and inspect the slope. Seems uneven in the middle.
