Poured walls - crack and water
I am hoping to get an honest opinion because trusting our builder is not even an option at this point. We moved in the home January 2013 the walls were poured in Sept. 2012. We happened to notice a crack this Monday after a large rain event. The builder waterproofed the house with a rubber material (or so it looked). The builder is saying they think it just needs a concrete sealer. This would make sense to me if the house was 20 years old or even 10. But it hasn't even been two years since we moved in. Any helpful advice would be fantastic.
