I just bought a 2003 1900 sq ft ranch home. The basement is huge. This house is barely 8 years old. The basement is poured concrete. There are no cracks anywhere in the walls (They look great). I dont know how basement walls today are actually poured, but it looks like they are done in around 20-24" sections almost because there are vertical lines running every 24 inches or so (didn't measure).
Anyways, I am planning to start remodeling the basement soon and was wondering if it would be worth dry-loc waterproofing the entire basement.
It's probably going to cost around 500 bucks to do, so I would rather not do it if it's unnecessary. I plan to live in this house for many, many years. Should I invest and do that anyways?
Waterproofing is best done from the outside, by having gutters/downspouts that gets water at least 6' away from the walls. And grading that does the same thing. Those two things will cure 90% of basement water problems.
Poured concrete is not done in sections, it is a monolithic pour(continuous). What you are seeing are lines left by the forms.
