I recently bought a home built in October 2024 in Edmonton, Alberta, and I've noticed cracks on the basement floor at about 11-12 spots where it touches the foundation walls. Given that the basement walls are insulated and covered with poly, I'm worried these cracks could indicate some foundation-related trouble. Should I consult a structural engineer about these cracks and check for compaction quality issues? What's the best way to address this situation?

Cracks appearing along foundation walls can be a bit alarming. While the builder’s perspective is valid, I think it would be wise to monitor the cracks over time. If they start widening or if you notice water pooling, that could be a red flag. Bringing in a structural engineer could help you figure out if you're dealing with any underlying issues with your foundation.
It sounds like the cracks on your basement floor might not have a direct impact on the foundation walls since the slab is usually poured separately. However, I totally understand your concern because visible cracks can still lead to water intrusion or ventilation issues. It's best to keep an eye on them and, if you're really worried, bring in a structural engineer to assess the situation further!

Thanks for the input! But I'm still curious, could those cracks actually allow water or radon to seep in? That’s my main worry.
