Decision support tool
Repair, level, resurface or replace?
Ten questions about what you can actually see from where you are standing. You get a reasoned result, the reasoning behind it, the options your answers rule out, and what to ask a contractor.
It works without any contact details, and it will tell you when the honest answer is that somebody needs to look at the site.
How this tool decides
It runs two passes over your answers, in a fixed order, and the rules are the same every time.
First, escalation. Certain combinations mean the useful next step is somebody standing on the concrete — movement that has got worse recently alongside real displacement, water running toward the house alongside settlement, soil visibly washing out. These override every other consideration, because recommending a surface treatment over ground that is still moving would be actively unhelpful. Every escalation rule needs at least two independent observations to agree, so no single answer can trigger one on its own.
Then, scoring — with disqualification first. Some options are ruled out by physics rather than preference. Foam cannot lift concrete that has broken into several pieces. An overlay cannot correct a slab that has dropped. Where an answer rules an option out, it is out regardless of how many other answers pointed toward it, and the result tells you which and why. What remains is scored across multiple inputs, and ties break toward the least invasive option, because you can always escalate after an estimate and cannot un-demolish.
Where your answers do not line up with any option cleanly, it says so rather than picking the highest of several weak scores.
What it cannot do
It cannot see your site, and the things that usually decide a concrete question are not visible from above: what the base is made of, how it was compacted, where water actually runs underground, what reinforcement is in the slab and where it sits.
It is not an engineering determination, not a structural inspection and not a safety assessment. It cannot tell you whether anything is safe to walk or drive on, and nothing it says should be read that way. If something about your concrete worries you, have it looked at regardless of what this page says.
About this tool
Do I have to give my email to see the result?
No. The tool runs entirely in your browser and shows the result immediately. Asking for contact details before showing a result would make this a lead form pretending to be a tool. If you want local help afterwards, that is a separate, optional step.
What happens to my answers?
They stay in your browser. If you choose to request local help after seeing the result, only which tool you used, its version and the result category are sent with that request — not your individual answers.
Why did it tell me to get an on-site evaluation instead of giving an answer?
Either your answers triggered one of the escalation rules — combinations that indicate ongoing movement or a water problem — or they pointed in genuinely contradictory directions. Both are real results. A confident answer built on contradictory inputs would be worth less than an honest one.
Will a contractor agree with the result?
Sometimes not, and that is fine. They can see things you cannot. The value of the result is that it tells you what to ask and what your answers rule out, so you can tell the difference between a contractor explaining something and a contractor selling something.
