Foundation Sealing

I am building an addition to our house which includes a basement and some crawl spaces. Has anyone used that concrete waterproofing black tar like stuff they sell at Home Depot ? It comes in a 5 gallon bucket. I was wondering if it is the same stuff or equivalent to what the hot tar guy sprays on ? Is it any good ? Is it easy to put on ? What are the pros an cons of doing it yourself ?

The con is that it is a "con job" to call it a waterproofer. At best you can call it a damp proofer that may become ineffective in a few years. Tar guys do not waterproof. They spray black stuff.

To get a dry basement, get rid of the water around the foundation instead of trying the impossible and "seal" the basement. If you get rid of the water around and under your basement, it become very manageable to have a very dry basement.

Drain tile at or below the footing level and rock backfill behind the foundation wall will collect the water so you can get rid of it.

You can cheaply parge the exterior of the wall or coat it with something like Thoroseal while it is exposed.
