The french drain and correct grading of the land is the most important part.
The tar like damp proofing really just stops moisture, not water. Search
this group using the group page of www.google.com and look up basements,
waterproofing and french drains and you will find everything you need.
Basically you need perforated drainage tile, a sock to go around it, tons of
gravel and special fabric to surround the whole thing so mud doesn't mix in
with gravel. Then you use one of the many tar like waterproofing substances
for the walls although like I said they really don't waterproof anything.

I am going to build an addition with most likely full basement
foundation made from cinder blocks. What's the best way to waterproof
the foundation. My home basement foundation is also built from cinder
blocks with no waterproofing as far as I know. I usually do not have
any leaks as long as gutters are cleaned. However I want to make
maximum effort to ensue the finished basement under addition will be
maximum waterproof. I read that many advanced waterproofing and
damproofing technique require specialized equipment and must be
performed by trained personnel. They are also quit expensive. What's
the best waterproofing method besides obvious pipe drainage that I can
safely and effectively do myself?
